Summicron 35 Version

Good afternood everybody and please be gentle with me because I have a very silly question: I've just acquired a mint Summicron 35 and I still haven't a definite vision if it's a fourth or a third version!
I konw both are great performers so I didn't care too much when I bought it but now it's really important to know what I have in my hands: here are some facts:
-S/N: 34401xx
-black, of course
-E39 filters
-focussing lever
-supplied with 12524 shade
-"leitz made in canada" engraved opposite of the DOF scale

Thanks in advance for the help

For Enrico De Rogatis, Sartorius's "Identifying Leica Lenses" says the 35mm/f2 Summicron [black]-with serial numbers between 2,970,000 to approximately 3,731,200 -- is the Fourth Version and "is considered one of the best high-speed wide-angle lenses in the world."-- bob cole

Hello,
I have one more question, because I have the same doubt. Are all the Fourth Version, from Canada? or do we find from Made in Germany too.? and if it is, what are the differences.?
Thanks.

I have a V4 35 Cron made in Germany. There are no differences in optical the formula between the German and Canadian versions. One note to using this lens: When mount or removing the lens always use the base of the lens and don't twist by grabbing onto the lens shade. Over time you can loosen the lens doing it this way (as legend has it).

In response to Laurent De Palma's question whether all the 4th Version 35mm Summicrons were made in Canada, Sartorius says that a March 1997 Leica p&hlet quoted Leica as saying that the 4th version was made in Canada for "many years."
Jim Arnold says that he has one made in Germany but Leica does not mention Germany, possibly suggesting that only small amounts were made in Germany. --bob cole

Thanks to all of you.
I was first using a 35mm/1.4 asph. And now with my 4th Version 35mm Summicrons, I have better immages.
But the only problem that I have, it is not on the opical feature, but the rear cap don't stay on the lens. And maybe it is what Jim mentioned on his answer. How to solve it.? I use the 14269 rear cap. Do we need to use one other version of rear cap.?
Thanks
Laurent

For Laurent De Palma, all of the rear caps for Leica M lenses that I am familiar with are made of black plastic.They tend to loosen in time and don't fit well. Just try another one from a different M lens and it may fit better. If you don't have extras, you can find them in your local Leica shop or on line. --bob cole

Robert is right on the mark. There is one guy on the Photo.net Leica forum that is always bashing the construction of the V4 cron. He claims they used glue instead of grub screws to hold the front element. If you use the lens shade to put the lens on or take it off you can place stress on the front element causing it to loosen.

For Brian De Palma, B&H in New York City is offering a generic rear M cap [new] for $19.50 while the Leica cap, it says, is $35. You should be able to find good, clean,used ones on this site for much less. Somebody on this site might even donate one for you.-- bob cole

I have both asph and v4 35 cron, the asph version is much heavier and solid in contronstruction, it seems Leica has added more than just a asph lens to make it feel so solid. my view that canadian made lens are not very solid in construction and had not choosen the best material, although you might think more highly of its optical quality, which is again a matter of taste.

Hi Robert,
I have three M-lenses, and I tryed all the diferent rear cap, but the problem is the same. After this I bought one new, in my local Leica shop, and nothing is better. I don't understand where is the problem, because on the other lenses the caps fit good.
Maybe it is my summ that don't want to be like the other one lenses.
Thanks
Laurent

for Laurent De Palma-- sorry I said Brian in a prior posting -- if none of your rear M caps made by Leica and marked Leica on the front fit snuggly when turned a little to the right, I don't know what to say.
The bayonet mount on all of the M lenses are supposed to be the same, so that they all mount correctly on the M camera. And the rear Leica M caps are all supposed to be the same so that -- unless worn -- they all fit any Leica M lens.
Ebay has several rear M caps for sale -- all of them generic and not made by Leica, one in Britain for sale for less that $1USD.
If convenient for you, I would take the lens with you to a Leica dealer and see if he has a back cap that will fit. Otherwise, maybe someone else on the Leica sites can suggest something. -- bob cole

Hi Laurent DiPalma,
Loose M-rear caps. Get some vinyl striping tape, which is thin, flexible and strong and put it on the flat surface of the cap facing the lens. It has solved the problem for me. Black electrical tape is too thick and doesn't adhere. Scotch "magic" tape is too thin and brittle.

for Laurent De Palma-- I believe I may have a solution to make your rear M cap fit snugly:
Looking at one of my M caps, I see that there is a plastic insert cemented inside and that the lens mount grips the insert at the bottom of the insert.
As a temporary measure only, so that you can can store the lens without getting dust inside, you might try cutting a piece of cardboard -- like the thickness of the cardboard on the bottom of a legal yellow note pad -- and seating the carboard inside of the rear cap.
If you have a compass, you could measure how round the cardboard should be and then slip the cardboard inside the cap. Then, when you place the cap over the lens mount, the cap should fit snugly.
Another temporary solution: If you are willing to experiment and maybe ruin the cap, since the cap does not fit as it is, you might try to loosen the plastic insert and re-cementing it a little farther away from the top of the cap. [at present, the insert should be flush with the top of the cap.]
Also if the insert is already a little loose, placing cardboard inside and then putting the cap over the lens might loosen it even further.
One last thought:
You might just take one lens off your camera and put the other lens on --and your problem will be solved. --bob cole
