Howard, I found in making a decision about a lens you must consider

the following factors. (1) Main application .......(2) Minimum

focussing required .......(3) Weight of zoom ....... (4) Speed of

lens (rather, amount of available light).

With my selection I was strongly guided by this forum. (ref "Older

Messages - EOS lenses - Birds & Lizards). I found the biggest factor

in my case was weight, followed by "Min Focussing Distance".

Kurt and Lanier, thank you both for your response. You both

mentioned the 300/4(IS) and Lanier mentioned min focussing distance

and made me aware of the importance of this feature when

photographing lizards. [i recall being too close on several

occasions]. However, this 300/4(IS) is out of my budget, hence, not

on the "shopping list". All lenses mentioned were similar price in

Australia (taking note that some/most,that I have selected, are

second hand).

Considering this selection, after some deep thought, I do beleive, my

main reason for wanting this lens is to catch those unexpected shots

that are usually missed through set-up time. So it comes down to

convenience and that relates to WEIGHT! This means my decision is

down to the 200/2.8 and the new 70-200/4, which are both less than

800 grams. Now, with the criteria that extention tube(s) and/or

Close-up lens may be required [i've never used either], I choose to

select a prime lens as opposed to a zoom.

Truely, I have never had an f2.8 lens and I am looking forward to

having plenty of light in my view-finder. So my selection (with a lot

of help from my friends) is the (second-hand) 200/f2.8L. I still have

to check out the lens hood........Thanks again

Canon EF USM 'L' lenses. I would be pleased if I could seek your assistance, to help me decide on the purchase of one of the following lenses:....... 1) 200mm- f2.8 (second-hand),....... 2)70-200mm- f4 (new),....... 3) 300mm- f4 (second-hand)....... 4) 70-200mm- f2.8 (second-hand). My main subjects are birds and lizards. Not for use at extra-long range (I have a tripod and a 600 glass for that). The camera is Canon EOS-5 and Manfrotto monopod. The 70-200mm -f2.8 is probably the heaviest lens I would consider (around 1,310 grams). I have a 1.4 X extender that I will want to use occasionally. At this time I am favouring the 200mm-f2.8 lens. Oh! I do like to use a "fill"-flash when close enough. ............. Thank you.

i agree with the response thus far. The most significant difference

in my opinion is the weight. If you want to travel light and use a

monopod, the f4.0 L is the lens (I am just in the throws of deciding

which lens I should buy). The f4.0 "L" weighs only 710 grams as

opposed to the f2.8 "L", which weighs in at 1310 grams. However, I

note you mentioned tripod, hence, weight might not be a big factor

for you to consider.........Regards.

Subbu, have a look at -

http://bobatkins.photo.net/info/faq30/closeup2.htm

This is a pretty comprehensive paper (8 x A4 pages)of Q&A's relating

to your subject. Answers were by Chuck Westfall (Canon USA - approx

1996).

The 250D has a maximum working distance of 250 millimeters (where

working distance is the nominal distance between the front of the

lens and the subject). Hence, is much stronger than the 500D close-up

lens, which has a working distance of 500 mm

I think that the E -3 diopter can only be the "E" eye-cup dioptric

viewfinder, which short-sighted guys, like me, would use. Not

necessarily for macro work.............Regards

As a avid reader of photographic forums and FAQ's, I would be pleased if anyone from this forum could tell me why the EOS mail List archives- Helsinki are no longer being updated.

I enjoy a balance of all available information.

Regards.

I have an FD extender 2X-B. From descripions above, this fits into

the "old type" category (silver ring). However, I thought this "B"

type extender was a later innovation (approx '82). Any clues as to

when the 2X-B came onto the scene.

Jim (and others), I have searched EOS5/2A/E User Guides (both Hove

and Magic Lantern) and cannot find any info regarding the above "over-

ride" - Have I got it right? <The AF assist (aux light emitter) on

the A2 camera, was designed to over-ride any AF assist (aux light

emitter) from the flash, namely, 430/530EZ>

My suggestion to J Viray was going to be - Add a hot-shoe adaptor to

lift the flash emitter a few centimeters and solve the problem

physically. However, this would be useless if the flash emitter is

disabled.

QUESTIONS>>>...... Is this permanent over-ride on the EOS 5 as

well?......Does this over-ride condition remain, when Eye Control AF

is "off"?......Does this over-ride condition remain when Eye contol

is "off" and focus is utilising (locked) centre position. ----

Regards.

At the risk of sounding like I'm under estimating your problem, are

you saying that when you use the 70-200L lens, that the flash in some

way finds this as an obstruction. I can appreciate that an internal

flash would, but not a 430EZ or a 540EZ. Could you expand or

simplify your problem.....Regards

T90 Eyecup- Totally agree with Terry (above posting). I was a little

premature when I said the EOS-1n was a "perfect fit". It does

appear, when viewed from below the eyecup, that one of the plastic

retaining prongs are skew and hence under stress. The corrective

action may be to fold back the eyecup rubber (which is glued into

position) and carefully file away plastics frame where it rubs on the

viewfinder shutter lever. Or alternatively, file the bulge off the

lever. About 1mm is required to relieve the situation. I will, in

the future, look a little more closely, before declaring "problem

solved!" .........Apologies,....Garnet.

Having waited a while for the answer to my question, I though I would

look through this site and others to find the address of a expert

person who knows serial numbers and models of FD cameras. He replied

today: (in brief)

"Initially, there was only one AE-P brochure issued by Canon,

although several revisions to the brochure followed, the black (and

the silver) appeared in this first issue. It must be assumed that

the black model option was there from the start. Hope this helps....

Thanks Joe. Regards to readers....Garnet

Eyecup T90 - Maybe, that little viewfinder blind lever, will cause a

problem. My objective, in ensuring the EOS-1n eyecup is a perfect

fit on the T90, is to go to the next stage of purchasing a Dioptric

Adjusting Lens (-2 dioptre), if it fits. I would presume the fit

would be the same as the eyecup mount. I hate manually focussing

with glasses. I will pursue this through another question.

Regards.....Garnet

Thanks again Kurt,"The penny has droped". I understand, well

explained. Regards Garnet.

Thank you Kurt for your prompt reply. I'll ponder your posting for a

while. Regards.....Garnet

Thank you John and Kurt for establishing that the camera program does

not recognise that an IS lens is attached. My difficulty is

comprehending how any program, that has calculated the amount of

light into the system, can adjust for two or more stops, without

utilising "exposure compensation". As I understand, the most

important feature of the IS lens is allow you to use a slow shutter

speed that would normally be prohibitive because of camera shake.

This lower Tv would allow the use of finer grain film, hence, better

images.

At this time, The way that I would achieve this, leaving DOF out

of the equation for the moment, is to load film (=< ISO100), switch

to P-mode. [incidently, IMHO, Tv and Av priority use the same program

as the P-mode, its just that one or the other is locked. The

adjusting of Tv or Av may be achieved in P-mode by moving the main

control wheel to the right or left]. I would then focus etc. and

read my Av and Tv. From the Av reading I would adjust so that it

reads approx two stops larger. I would note the Tv, which should be

slower and fire. Am I on the right track?

Do you see the day where they will have the control dial reading both

"P" and "P(IS)". Regards.....Garnet.

Terry, Ref your last posting. Indeed, the T90 was fitted with an

eyecup (Possibly in some countries only). The T90 brochure, at

http://garycoombs.com/Photography.htm, clearly shows the eyecup. Of

more interest to me, is what you did not like about the EOS-1n eyecup

fit to the T90. I found (and reported to David) that it fitted

perfectly. Was it too loose? too big physically, too small?.... and

what would you modify? Applying your finger tip to the viewfinder

blind lever is difficult and I did notice initially, that it was

extremely difficult to remove the eyecup from EOS-1n. For me it was

the perfect solution. Regards.....Garnet

David, I have been looking to buy a T90 and have examined several.

What I have noticed is that the ones that are for sale are usually

missing the eyecap. Yesterday, I actually asked the salesperson to

try the EOS-1n eyecap on the T90. As Terry suggested in the last

posting, it fits perfectly and won't fall off. Also, you can still

manage to get to the T90 small shutter blind lever. Please consider

that your T90 eyecap solution now tried. Regards.....Garnet

Using a 28-135mm IS lens with my EOS 5 (hand held), as a new user I always use "P" mode. What possible benefit could I expect to attain, other than minimal camera shake? Does the camera's program know that it is an IS lens and hence alter the "Tv" to suit? Or should I always use a slower film?

Regards Garnet.

Geoff, I don't have documentary evidence but based on a Canon history

investigation I'm doing as a hobby, I beleive the 299T must be the

dedicated Speedlite for the T80 (first auto focus Canon model) this

camera came out in 1985. My logic is (1983)T50---- dedicated 244T.

(1984)T70---- dedicated 277T. (1986) T90----dedicated 300TL. The

suffix "T" also indicates the speedlite is made for the T series

rather than the "A" or EOS family. Regards Garnet

I am confused as to what year the AE-1 Program "Black Body" appeared on the scene. My investigations reveal that the AE-1 was first introduced (silver body) in 1976. Then came the A-1 (black body) in 1978. Then, the AE-1 Program in 1981, this had a silver body. When did the AE-1 program coime out with a black body? Regards Garnet.
