Hello Lester,

is this macro lens hood a Canon product? Who builds this kind of stuff?

Thank you in advance!

Hello Xinyang

if you want Gepe slide mounts you need this kind: Mfr# 452603 ? B&H# GESM2603

http://www.bhphotovideo.com/c/product/20541-REG/Gepe_452603_22x54mm_Medium_Format_Anti_Newton.html

These mounts have an outer size of 7cm x 7cm and will fit into the PCP 80. A big drawback: You have to cut your XPan slides 4-5 mm on each side.

Hello Wolf!

The flatness problem is anything but a rumor, especially when the film lasts a little longer in the insert. I've taken two identical shots with a 2.8/45 focussed to infinity, on the tripod with mirror lock up, film type 120. On the second shot you can see a real difference in sharpness but only in the upper central part of the slide (about a third). This is exactly the part of the film which was a long time bended over the guide roller of the insert.

Since that time I'm using the vacuum insert and film type 220 whenever possible. But in my experience the usage of film type 220 instead of 120 is more effective than the usage of type 220 in the vacuum insert vs. type 220 in the standard insert.

*Three* working days for the repair of my Tele-Apotessar 4/350mm by Kyocera/Germany. I've buyed a TLA 360 flash and this lens was the only one where the autozoom reflector doesn't work correctly in combination with. Even though the guarantee has run out it was repaired for free. Those days are gone forever ...

Hello all!

Maybe this is more of interest for readers of the medium format forum ...

First, as we all know it's impossible to stop down the diaphragm of the Contax 645 lenses manually. An adaptor only makes sense on long telephoto lenses wide open. I've dismantled a Contax 645 extension tube 26 mm to make me two different kind of adaptors for my Contax 645 system:

The back part (the part which fits on the 645 body) was modified to accept M39 enlarger lenses for macro work and (via additional adaptor) my Luminar 63mm (microscope mount, additional adaptor made by Novoflex).

The front part (the part which fits on the 645 lens) was modified with the help of a lathe and with a common T2 adaptor for Canon EOS. It's abit difficult to describe all the things I've done but if anybody is interested in I'll post some pictures of my "construction".

Hello Steve,

I would also try to contact Phase One for a used P back, because they recently launched the P+ backs.

Hi!

Have a look at the "Novoflex Reverse Adapter for Canon EOS" in combination with a standard zoom lens like 28-105 or 28-135. Magnification up to approximately 3x (at 28mm) with full coupling of diaphragm and metering.

Uli

Hello Bernard,

try Isarfoto, Germany, www.isarfoto.com. Mr. Bothe ships worldwide. He sells a standard Contax 645 set with an additional waist-level finder via customer order. Talk to him perhaps it's possible to separate the waist-level finder.

"The Canon collar mount for the 100mm macro is not well designed at all. It comes in 2 pieces and they are not easy to put on the lens, the fit and feel is cheap (nothing like the L collars) and I wouldn't recommend it for those reasons alone (never mind the exhorbitant price). I hate it!"

Exactly that's the reason why you should have a look at the collars made by "Rainer Burzynski, special equipment for nature photography". He has a lot of other stuff in his program to work around the design flaws made by many camera and lens manufacturers.

Uli

Hello Brian,

maybe not a less expensive alternative but a much better one are the tripod collars made by Rainer Burzynski, Germany. Have a look at www.isarfoto.com and search for Burzynski makromount tripod collar.

Hello Michael,

I'm also using this lens since several years. Another outstanding feature of this lens is the nearest focussing distance of 1.9m. The 350 Tele-Apotessar is in practice a long focal length macro lens perfect for nature photography.

Uli

Hi Michael,

take a piece of double-sided adhesive foil and stick a small semi-ball (hemishere) on the button for the mirror lock-up. What works great are the small eyes for teddy bears where you cut off the hooks at the flat side. I wonder who has designed this impractical button of this great camera ...

Hello Milan,

I've shot several pictures which where definitely out of focus (partially in the upper third of the image) because of film bending so I bought a second magazine with the vacuum insert. Therefore I switched to 220 film. But I can't see any visible (!) difference between a 220 film in the standard magazine and a 220 in the vacuum magazine.

Regards

Uli

Hello James,

the Novoflex flash system has definitely a special adaptor for TTL light metering with the Contax. You need the generator and the ring flash. The only problem might be the large diameter of your lens front thread (72 mm). I'm using the generator in combination with the FlashArt on my 645. The generator and the flashes are really not made by Novoflex they are a third party product. I'm sure there are some other flashes out there which are using the same generator and adaptors under a different brand.

Uli

Hello Milan,

I've modified my Bellows Lens Hood GB-B1 so that I can use resin ND grads with a width of 75mm (a cut Cokin P filter).

Uli

Hello !

Have a look at www.hassi-foto.de, go to "Extrablatt" -> "Accessories" and scroll down to "Objektivhalter". Mrs. Hoeppner will send it worldwide.

In former times Gepe builds cutters for 6x7, 6x6, 6x4.5 and 4x4, the latter I have. The problem is the gepe cutters cuts both sides of the slide all at once so it's rather difficult to cut a slide with a different format than the cutter is build for.

Hi Victor,

unfortunately Zeiss has designed a lot of great lenses for different camera manufacturers which you can't buy (4.0/600 Tele-Apotessar for 35mm Contax, zoom lenses with central shutter for Hasselblad, and many more)

Uli

Hello Gary,

I've also observed film flatness issues but only when the film remains in the magazine for a couple of days between the shots. Since that time I use film type 220 whenever I can. I own one magazine with standard insert and another one with the vacuum insert. And it does make a difference! But I think the main improvement is the usage of 220 film type vs. 120, a vacuum magazin adds yet another (IMHO) smaller effect.

Uli

Hello Randy,

the 645 Pro has TTL flash control with dedicated flashes. A feature I always missed as a formerly owner of a 645 Super.
