I used a Peak 4x loupe for years but saw so many people raving about
the Toyo loupe that I figured why not give it a try for $30. I really
didn't like it, only because it is round. The Peak loupe was square so
that you could get right up into the corners, which is often where
your problems, particularly vignetting, will show up. With the Toyo I
couldn't see in the extreme corners. I quit using it and went back to
the Peak loupe. The Peak loupe was a little more expensive - around
$50 or so as I recall. Personally I wouldn't use anything except a
square loupe for ground glass focusing. The folding focusing hood on
my Linhof Technika is totally useless except as a ground glass
protector so I don't use it and use a dark cloth (Darkroom
Innovations) instead, so length of the loupe wasn't a consideration
for me. The Peak is short and probably would be difficult to use with
a folding focusing hood.

Although the 150 mm G Claron is optimized for 1-1 it isn't a true
macro lens and actually works very well as a general purpose lens.I
use mine mostly as a general purpose lens but occasionally as a close
up lens and it does both quite well. It also has lots of coverage,
which is nice.

I have a vignetting problem with my 90 mm F 5.6 Super Angulon lens. I
plan to get the wide angle adapter that Lee recently started selling
but haven't done so yet so I don't know how much it will help, though
others say it works great. Very aggravating to me that Lee sold a
product with known vignetting problems for quite a few years before
doing something about it.

I don't think that macro photography is one of the strengths of large
format. There are several problems. First,in order to get even to a
1-1 magnification the lenses tend to be on the long side - 150
and up. Secondly, you generally have a very long bellows
extension to get to 1-1, so it becomes difficult to see the
subject with so little light getting to the ground glass. Third,
large format in general can be cumbersome and somewhat unwieldy
when trying to focus on a flower petal that is three inches from
the lens. Fourth, because of the shallow depth of field you tend to
use very small apertures and because of this as well as
the long bellows extension, often end up with really long shutter
speeds. If you're photographing something that moves, the slightest
breeze can ruin your photograph and when you're using shutter speeds
of 15, 20, 30, or more seconds, which is by no means unusual, the
likelihood that a breeze will occur sometime during the exposure is
pretty great. None of these problems is insurmountable and I'm sure
some people do a lot of macro work with large format but personally I
wouldn't get into large format with the idea of doing macro work with
it. You might use large format for landscapes, and maybe portraits,
but stick with your medium or 35 mm formats for the macro work. Just
my opinion. Brian

Andrea - I don't know what experience, if any, the other people
who responded to your inquiry have had with Tachiharas but mine has
been an excellent camera and a terrific value for the money. Its well
made, sufficiently sturdy for any weather in which I'm likely to be
able to photograph, very attractive finish, decent movements and, best
of all, very light for an 8x10. The only drawback for some people is
that with the double extension model the bellows is on the short side.
Tachihara makes a triple extension model but I've never seen it and I
assume it is somewhat bulkier and heavier than the double extension
version. FWIW, each year a magazine here in the U.S. called "Photo
Techniques" publishes a list of what they consider to be the 25 best
cameras presently made. The Tachihara was included in this year's
list. I mention this, not to suggest that you should buy the camera
because it was inlcuded in somebody's list, but because somebody who
is supposed to know something about cameras thinks it is a pretty good
camera and you certainly don't need to apologize for being interested
in it. I became intersted in it after taking a John Sexton workshop
and seeing the one used by a terrific photographer who at the time
was John's principal assistant. I would take the previous responses
with several large grains of salt - one of the responders posts to
this group fairly often and seems to be more interested in trying to
be clever than in providing objective and accurate information. I
don't know the size of Sinar's lens boards so I can't answer that
question.

Bosscreens are sold by Bromwell Marketing. The owner, Ted Bromwell, is
a very nice guy and very helpful. You can get contact information from
Bromwell's advertisements in "Shutterbug." I bought mine about three
years ago and it cost around $150. It was the most expensive of the
options I was considering but I thought it was well worth the price.
Technically it isn't an enhancer in that it doesn't brighten the light
but it is considerably better than a plain ground glass and is much
easier to focus when using a loupe than is a fresnel lens. I live in
Florida and used it during the summer, taking no precautions against
excessive heat that I wouldn't take with any camera equipment, and had
no problems. I certainly don't think you'd need to keep it in an ice
chest unless you plan to drive to Death Valley in August and park for
a few days with the camera in the car or something similar to that. If
you normally take reasonable precautions against overheating film and
equipment, I think those normal precautions should be sufficient for
the Bosscreen.

I use and generally like the Lee system. I too have had problems with
vignetting when using a 90mm lens and a "normal" adapter. I guess I'll
have to get the wide angle adapter, which Lee didn't make when I bougt
my stuff several years ago. If you consider a polarizer filter to be
mandatory (as I do), you should be aware of the fact that the Lee
polarizer cost about $150 when I bought mine several years ago and
maybe more now. At the time I bought mine Lee was the only company
that made a 4x4 polarizer so if you wanted to use a polarizer with the
Lee system you had to buy theirs. Maybe Cokin or somebody else makes a
less expensive 4x4 polarizer today, I've had no need to check.

Multi-coated lenses usually will reflect two different colors when
placed at an angle to a light source and moved around, a purplish
color and a greenish color. In the lenses I own that I know are
multi-coated, these two colors can be clearly seen as the lens is
moved around at an angle to a light source. I thought, but am not
certain, that if you see only a purplish color the lens is single
coated and if you see no color at all the lens is uncoated. However, I
don't own any lenses that are uncoated or single coated so I cannot be
sure of this. Perhaps someone else can confirm this or correct me.

I use the Fuji 400 mm telephoto lens and it's excellent. I've read in
magazines and on the net that Fuji in general is the equal of the
other three makers. As someone else mentioned, Fuji pulled its US
distributorship some years ago so the lenses, while available (from
The F Stops Here and Midwest Photo Exchange and probably other
places), aren't as accessable as the other brands. It took about a
month to get mine (from The F Stops Here) and I think that's about
normal.

The November, 1989 issue of "View Camera" magazine included a very
brief, and not terribly useful, article entitled "Buying the Used
Linhof Technika." Copies can be ordered from the magazine but, apart
from listing the specs for Technikas III through Master, the article
isn't very good for information about the differences among the
different Technika models, the article in Tuan's Large Format Home
Page is much better). Anyhow, here are the specs for the Technika V as
given in the article: Bellows extension: 400 mm; Camera back
extension: 35 mm; angles of drop bed: 15 and 30 degrees; max front
rise 45 mm; max front fall 6 mm; front shift (each way) 25 mm; lens
board tilt 15 degrees forward, 15 degrees backward; lens board swing
(each way) 15 degrees; back swing (each of four ways) 15 degrees. If
you compare these to the Master specs you'll see a few differences but
the only one of any significance, IMHO, is the lens board back and
front tilts (30 degrees with the Master, 15 degrees with the Tech V).
Hope this is the info you were looking for. Brian

I remember reading an article several years ago, I believe in the
now-defunct "Camera and Darkroom" magazine or perhaps in "Photo
Techniques" (under its old name), in which the author performed tests
on the requisite wash times after using various clearing agents. If I
remember correctly he found that 15 minutes was adequate after using
Heico on fiber base paper. Just to be safe I use 20 to 30 minutes. Two
minutes is way too short.

I've read numerous complaints at various net sites about film spacing
problems with the P67/ The weak link in the P67 seems to be the film
advance/shutter cocking mechanism. In some cases irregular film
spacing has been a prelude to complete failure of the system. In my
case I've had the camera for roughly four years now and it has seen
limited use - perhaps 150 rolls maximum have gone through it. In that
time the film advance has failed twice. When it happened the second
time I posted a question in rec.photo to other P67 users, asking if
they had encountered the same problem. Many people hadn't but enough
had to make it clear that mine wasn't an isolated problem. Since
Pentax repaired it the second time it hasn't failed but I'm getting
some irregular spacing now.

As others have noted, you stretch the cloth over the rear standard
only. I believe that Darkroom Innovations makes two versions of the
cloth, one for field cameras and one for studio cameras. Assuming
you have a field camera and the field version of the Darkroom
Innovations cloth, when you stretch the elastic over the standard
the openings on the left and right sides of the cloth should allow you
to reach the controls (such as the control for back tilt) on the left
and right sides of the back standard. If you're having trouble
operating these controls you might want to check with Darkroom
Innovations and make sure you have the correct version of the cloth
for your camera. As a matter of interest, the cloth was designed by
Phil Davis' wife and I agree with the others who have posted here -
it's a vast improvement over the traditional dark cloth.
-
I own the Fuji 400 F9 telephoto lens. I haven't found it to be
significantly more difficlt to use than a normal lens. I think that
the things you read about the nodal point being in front of the lens
and the effect of this in operating a camera with the lens sometimes
make it seem to be more of a problem than it is in practice. Certainly
tilting it doesn't degrade the image.
-
I've never used the Tele Arton but I do own a Fuji 400 telephoto.
Before buying it I was concerned about some of the problems with
telephoto lenses alluded to in the previous message but in practice I
haven't found it to be significantly more difficult to focus or
otherwise use than a normal lens. My camera has base tilts so I was
used to re-focusing a good bit. If yours has axis tilts maybe the
telephoto lens would take some getting used to but I don't think you'd
have any major problem with it.
-
I have the Condit system and it does work very well. However, it was
fairly expensive. As I recall, the punch and frame were in the $400
range. The punch I ordered can be used with anything from 35mm to
5x7. The punch for 4x5 alone was a little less but not much. Having
now used it a good bit I realize that aligning the mask with the
negative isn't all that difficult a task and there are other, far less
expensive, ways of doing it. So I think if I had it to do over again I
probably wouldn't spend the money for the Condit system, excellent as
it is.
-
I agree that you need a decent dark cloth for openers, and the one
sold by Darkroom Innovations is excellent. Next I would try the
fresnel lens just because of its price. See how you like it - if
things still look too dim you could try the Bosscreen but you need to
realize that the Bosscreen strictly speaking isn't a "bright screen."
What it does is spread the light out evenly around the ground glass (a
non-technical description), thus allowing you to see and compose
somewhat better than with just a ground glass. I had the Bosscreen on
my Technikardan and it was a big improvement over the plain ground
glass that came with the camera. For me, the plain ground glass was
useless - I had to keep moving my head around to find the bright
spot and I couldn't view the entire scene at once and so couldn't
compose anything.l The Bosscreen is also better than a fresnel lens
when using a loupe because the loupe enlarges the circles in the
fresnel lens, thus making it a little more difficult to focus. Again,
though, if the fresnel lens is only $30, and the Bosscreen is around
$150, why not start with the fresnel lens?

No one mentioned the 75mm shift lens. Apart from its shift
capabilities, which can be useful with trees or other vertical
subjects, it'slens when used as a straight medium wide angle lens
(about the equivalent of a 35mm lens in the 35mm format). I carry the
Pentax 45mm lens and it's also very good but lately I've been using
the 75mm more. The stop down metering isn't a problem once you get
used to it, which takes only a few shots. The only disadvntage (apart
from price) is that it's large and heavy so I leave it out if I'm
going on a long hike but for a half day or so of hiking it's fine.

This question is ancient history by www standards but for the benefit
of others who may have the same or similar problems, I'll post this
response.
<p>
The film advance system in the P67 is its Achilles heel. I don't know
why but complaints about irregular spacing, overlapping picture
frames, and outright failures are very common if you read the
different medium format sources on the web. Actually, if all you have
is irregular spacing between frames that's the best case scenario. The
next best is to have two pictures overlap - at least the other 8 or
18 are o.k. The worst case is complete failure of the film
advance/shutter cocking mechanism stops as you try to make the second
photograph on your once a year trip to Utah. That's what happened to
me. It was the second time that had happened in the three years I
owned the camera. The first time occurred a few months after the
warranty expired and the camera was repaired by a local repairman. It
worked fine for about a year after that repair, until my Utah
experience. After the second failure I sent it to Pentax for repair.
They charged around $250 as I recall but it has worked fine in the
year or so since then, although I do get some irregular spacing
between frames. I might add that I rarely use the camera (I do mostly
large format work) and I bought it new. I also am extremely careful to
advance the film slowly and evenly. Hopefully whatever causes this
problem with these cameras will be cured in the new P67II.

I've owned (to the tune of about $300 used as I recall) the Linhof
folding focusing hood and it was useless. The sides were made of
fabric and so you couldn't press your head firmly against it to keep
out the light. I've seen a friend's Calumet reflex viewing hood and it
was nice but it was too bulky for me and if you don't mind the upside
down inverted image you probably wouldn't want to pay the price
of a reflex hood anyhow. Based on my Linhof experience, I'd suggest
that you try out whatever you are thinking of before buying it. I
also second the Darkroom Innovations "darkcloth" recommendation.
That's what I use and I like it. It's a little more trouble to put
on the camera than a conventional darkcloth but once it's on it's a
delight. It's also much more compact and light weight than a
conventional dark cloth.

I'll second some of the favorable comments about the Tachihara. I've
been using mine for about two years now and I think it's an excellent
camera. It is well constructed and quite solid. I've never had any
stability problems. The finish is attractive, it's easy and quick to
set up and take down, and best of all it's light. The weight savings
with the camera, plus the ability to use a lighter tripod and head,
really makes a difference when you're walking. The idea that B&H
doesn't carry it because it doesn't meet their standards is, IMHO, BS.
I like B&H and buy many things from them but I doubt that they test
every product they carry. The only drawback to the camera is the
relatively short bellows extension - 13 inches. I got around this by
buying a 400mm Fuji telephoto lens which works fine but was somewhat
epensive. If you want to do 1-1 macro work you can use the 150mm G
Claron lens. It's a good lens but I agree with those who have said
that using a 4x5 camera for macro work is perhaps not the best idea -
I bought the G Claron for that purpose but found that the additional
time and trouble involved aren't justified by any significant increase
in quality as compared with medium format macro work (at least for me
- others may disagree). I would recommend the Tachihara without
reservation. Even if you later decide that you want a Wisner or other
similar camera for some reason, you can always keep the Tachihara and
use it for camping trips or long hikes. It weighs about half of what
the Wisner Traditional and Technicals weigh. Finally, I agree with
those who recommend buying it new. If you read "Shutterbug" you see
that used prices are all over the place - Del's and I believe KEH
recently were advertising used Tachiharas for a higher price than
Adorama's new price advertised in the same issue!

I'm far from being any kind of an optics expert but I do know that
there is no ANSI or other industry-wide standard for determining when
a lens is an "APO" lens and when it isn't. A lens is an APO lens if
the manufacturer decides to call it an APO lens. Therefore, as someone
else has pointed out, the "APO" designation, by itself, means very
little.
-
I don't know if you're seriously considering a purchase of the older
version of the 55mm lens or not but if you are be sure to at
least physically look at it first, or buy it with a right to return
for any reason if you don't like it. I say this because it is a
really, really big and heavy lens (as you might suspect from the 100mm
lens diameter). I had always heard good things about this lens and
considered buying one until I saw one at a camera show. For me, it
was just too big and heavy to be practical in the field. You might
very well feel differently, as others do, but at least look at it
before you buy (or make sure it can be returned).

Gary - Re the comments you've heard about the TTL meter - wrong,
wrong, double quadruple wrong. I use the TTL meter extensively and
have been amazed at how accurate it is considering the fact that it's
not matrix metering, it's not even center weighted metering, it's just
a good old primitive match needle system. Nevertheless, to my
surprise it works very well. When I first bought it I tried taking two
photographs of the same subject, one with the exposure based on the
TTL meter and the other with the exposure based on my Pentax Digital
Spot Meter. I seldom saw a signifcant improvement with the hand held
meter and I now use it only when I know I'll be able to shoot a whole
roll in the same light and can develop the roll to zone system
standards. Otherwise (which is most of the time) I use the TTL meter.
I would guess that the person who is telling you how bad it is has
never used it.

A friend of mine was recently going through the same dilemmas that
your are. He solved it by purchasing a $175 round trip ticket to
Atlanta.In advance of his arrival he called a dealer there who sold
all of the camera brands he was considering (Quality Camera), asking
that they all be set out on tripods for his checking upon his arrival,
spent the day checking them out, bought one, and flew home with it
that night. I don't know where you're located but airline tickets are
pretty cheap these days and most major cities have at least one dealer
that carries many of the various large format brands.The price of an
airline ticket may seem expensive but in the long run it may not be so
expensive. I bought my first large format camera (a Linhof
Technikardan) in much the same way you're doing it (word of mouth,
reading, checking specs, etc.). I didn't like the Technikardan, sold
it at about a $300 loss, bought my second camera (a Tachihara), liked
it a lot but became enamored of the great solidity (?) and engineering
of a friend's Technika, sold the Tachihara at a $150 loss, and bought
the Technika. So I'm out of pocket $450 not to mention the cost of the
Linhof accessories I sold when I sold the Technikardan and now need to
buy back for the Technika. It would have been a lot cheaper just to
have bought an airline ticket. Think about it.
