Contax Shutters - The Real Story

I've never read the famous patents on the Leica shutter, so often referred to; I know they had some on the rangefinder. Whatever protection they had on the horizontal, cloth, pin timed focal plane shutter didn't do much to stop Exakta from making one... or Perfex, or Detrola by the end of the 30s. And I can testify personally that they DO burn through, if you happen to have your camera lying on the car seat while driving home from work.... the camera has a nasty way of winding up lying on its back, and it's hard to control the location of shadows as you drive in different directions.

Doug, you do remember me, right? :D
 
Come on guys, you are debating about which one is better - and you chose the two BEST rangefinders from those times. This debate will have no end. It's useful for the info jammed into it, but we should keep in mind that people are different and have their preferences and are proud of their choices blah blah.

I don't have any personal experience with Leica, and will never have ($$$$) but I was able to afford a contax already. Yes, with a lens!
It's a great tool, and I appreciated it even more when i took a look inside. I'm sure a Leica is not worse at all.

I'll be happy to ... assisst you... (yeah, that's it!) in any way possible. :angel: :D

I'll keep things civil & respond to each of your points below.



Your analogy to the Elmar & Tessar is appropriate. However, you can only assert, not prove, that each company made its decision *entirely* based on avoiding patent infringement. Of course patents influenced Leitz's decision to not copy the Tessar & of course patents influenced Zeiss Ikon's decision to develop a different shutter for the Contax. What you can't do is prove that the patent was the main motivation & inspiration behind each decision. Shutters aside, you ignore the obvious fact that the Contax had a superior RF to the TM Leicas, which accounts for part of the higher manufacture cost for the Contax.


You have repeat several times about this , as I said time has proved Contax shutter design is a failur, no one copy it. Leica's 1.5x rangefinder can accurate focus up to 135mm, beyond 135 both have to use a reflex box. we do not need overkill, this is one of the reasons that made Contax fail in the market plus poorly designed shutter.


This is a wash as I've heard different things from different camera technicians, & no one out there has tested enough shutters to make any other than an educated guess.

that's easy how many samples do you need to get a conclusion? every contax made since its day? go buy a shutter tester do it yourself, it is not difficult thing to do and an accurate shutter tester is not expensive either.



I'll repeat the points I made in the previous (deleted) thread & in my previous response on this thread: (1) many, many more Leicas were made than Contaxes; & (2) the fact that the Leica shutter is simpler & requires less maintenance does not in & of itself make it a better design unless simplicity & ease of maintenance are your only criteria--the Contax was made w/the expectation that it would be maintained by skilled technicians.

You have no prove to back up your claim that Leica made more cameras than Contax in a giving peroid. Camera is just a tool, not a fancy fashion show, if it is relaiable, durable, less trouble, minimum maintenance that's what a tool designed for. if you are trying to make a point which camera is more complex, more difficult to repair, I agree with you - Contax win



Another wash. The German Air Force & Army used Leicas, but the Navy used Contaxes. From my knowledge of gov't procurement, you can't assume that such decisions are made solely on technical superiority. Moreover, outside Germany, the Contax, not the Leica, was the system of choice for most photojournalistic establishments (e.g., Time-Life) & many famed photographers (e.g., Ansel Adams, Robert Capa) notwithstanding Leica's "1st mover advantage" (greater installed base) & lower prices.

show me how many military Contax has survived the war, you forget to maintain lots of famous Leica Photographers, more than Contax user.



In the absence of statistics you can only assert, not prove, that burned shutter curtains are "very rare." Folks on this forum alone, hardly a large sample, have provided real life examples of it happening.

It is the same, you have no prove that the burned shutter curtain is common.



1st, to repeat another response from the earlier deleted thread, you ignore the simple fact that, unlike Leicas, the Contax/Canon/Nikon metal shutter curtains rarely have to be replaced. That's a bit like saying that's its better to make clothes out of paper because you can just throw them away rather than having to wash them; they may work in the doctor's office, but doesn't generally hold true for going out in the street. 2nd, it is not unreasonably expensive to get a Contax/Canon/Nikon shutter curtain replaced & while you can get away w/using an old sock or whatever to serve as a Leica shutter, the technically-correct rubberized cloth is not something you buy @ the corner hardware store.

like most repair shop I use film exchange bag materal. I can buy a bag very cheap so material wise only few cents, and you can order from micro-tools for few dollars, can Contax/Canon do that? My USA army retired M3 went throuh hell but the shutter curtain still good.

Ed Romney, a very good camera repair technician, does not recommend Contax as a good used camera to buy, is this mean anything to readers?. due to these problems even Contax cost more to buy when they was new but cheaper than Leica when they are used.

chendayuan,

could you please not use blue for the color of your posts. It is almost impossible to read your text on a black background!

Thanks!

Ok, when I win that Robot Royal which is on the block at the moment, I'll sell Kiev and Zorki as I then have the worst shutter in the world. Nobody copied Robots rotary shutter :)

look at Olympus Pen's shutter. some people miss the point about this debate, we as users do not care about the brand, we treat camera as tools. this is not a brandname holy war. I do not care Leica/Contax/Nikon/Canon/Olympus, if it is a well layout/designed tools, we will enjoy to use them.

(1) The mere fact that the Leica shutter was copied does not make it a better shutter, just that it's easier to manufacture. As to the Contax's superior RF, who's to say that it's "overkill." I find the RF on my IIIc & Tower 45's to be barely adequate, & hardly ideal, for shooting a 135mm.

(2) The Contax was hardly a "failure" in the marketplace, except to the extent that all RFs eventually "failed" in the wake of the Nikon F. The facts are clear on this one.

(3) It is a simple fact that Leicas were produced in greater quantities than Contaxes during the time when both where in competition. Period, end of story. If I had my books w/me, I could give you a citation. Google may help you pull up the production figures. I don't see why you dispute this fact as it would support your opinion that Leicas are better.

Yes, a camera is just a tool & not a "fancy fashion show," but camera "success" is not just a popularity contest, either. Many more cameras today have the Copal-style metal-bladed shutters, does that make them superior to your vaunted Leica? More SLRs are made than RFs, does that make them better? In some ways the answer is yes, in others, no.

(4) I know all of my Contax shutters (3 IIa's, 2 II's) are accurate in field use. I'm a shooter, not a camera tech. Likewise, my Leica bodies (IIIc, M2, M3, M6 TTL) have all been accurate, too, although in my experience the Leicas tend to be too slow @ 1/1000th on more occasions than the Contaxes, which are consistently "on target" @ 1/1250th (verified via slides). As I say, a wash, as almost all of the vintage bodies had to be professionally CLAed, @ similar prices BTW, to be brought up to spec. My Hexar RF & G2 beat all of them in accuracy.

(5) Not that many military Leicas survived the war, either. Miliitary & Nazi-engraved Leicas & Contaxes are both very rare & collectible. The only reason I brought up famous photographers & institutions like Time-Life using Contax is that far from being considered unreliable & troublesome, the Contax system was considered reliable & very tough in field use.

(6) Again, the fact that the Leica shutter curtain is easy & cheap to replace doesn't answer the fact that Contax/Nikon/Canon metal shutters hardly ever need to be replaced in the 1st place. I've never heard of anyone's Contax needing to have its shutter curtains replaced, only the shutter cables on the pre-war models, nor have I heard of anyone needing to replace the steel shutter curtains on a Canon P or the titanium shutter on a Nikon SP. My point is that the Contax shutter may be more difficult to fix, but I see no proof that it breaks down or needs to be adjusted more often than a Leica shutter. Your argument re: overall maintenance costs only holds true if you can prove that the Leica shutter breaks down or needs adjustment less often than a Contax shutter to the extent that it outweighs the Contax's greater durability of materials, & you can't prove that point based on anecdotal evidence. As I stated above, almost all of my vintage Leicas & Contaxes have needed CLAs to get them running properly (exceptions being the M6 TTL, which was practically new, & 1 of the Contax II's, which was purchased already CLAed by Henry Scherer).

(7) Ed Romney is hardly the final authority on matters of camera mechanics. The fact that used Contaxes are cheaper than many (not all) used Leicas is influenced by many factors having nothing to do w/the engineering of the bodies.

My bottom line & last word(s):

Whatever floats your boat. I like Leicas & Contaxes. I just don't think Leica shutters are superior; when it comes to Leicas I like the M series because, to paraphrase James Carville, "it's the RF/VF, stupid!" But I also like TM Leicas & Leica copies because they're small & chicks think they're cute.

My first post is Leica M is still the king of rangefinder, this post is the 'true' story of Contax shutter
1. you have not provided enough evidance to remove the Leica M from the King's throne
2. The "true" story about the contax shutter has no evidance to prove to be true

(7) Ed Romney is hardly the final authority on matters of camera mechanics. The fact that used Contaxes are cheaper than many (not all) used Leicas is influenced by many factors having nothing to do w/the engineering of the bodies.

1. Have you take apart any of the Leica, Nikon, Canon, COntax? Ed did, I did too, Do you have any first hand experience regarding these camera design and engineering?
2, Since Contax is famous brand what made them less expensive than Leica?
 
Chendayuan - contax is NOT a famous brand anymore. They are (the rf's) out of production for tens of years. Get out on the street and ask random persons if they ever have heard about Leica. A large procent will say yes it's an expensive camera. Now ask them about Contax. Almost noone. Not even about the new G1/2 and the medium format contax. I know this from my own non-photographer friends.
That's what makes them NOW less expensive, first of all.

I did take a contax (IIIa col.dial) apart, incl. taking the shutter module out and disassembling it from the bottom inside. A synchro-compur shutter is nothing compared to the complexity of the contax "a" type shutter. I can imagine that the production+assembly costs were much higher than for any other shutter type.

The 1/1250 vs 1/1000 fastest speed was a marketing joke. The difference is one fifth of an f-stop. It will not stop a hummingbird in its flight. Even slides can't react on that difference.
It's the same today - people whine about "only 5 frames per second instead of 7 and a half" and point it out to prove that a SLR body is worse than the other one.

Finally, - kings and queens of today only have a representative/dimpomatic importance. They are not the ones rolling the ball...

With all my respect
Pherdinand.
 
Is there any purpose to this discussion? This reads little better than the Nikon vs Canon ad infinitum arguments that can easily be found on PhotoNet for those who enjoy such things.

Hey, it's all in good fun. ;) If Chendayuan really wanted to put me in my place, he could have simply asked me why Zeiss Ikon went w/the Leica-style shutter in the Contarex (although I'm sure ZI had their own engineering reasons for doing so).
 
They were copying the highly successful, landmark Contax S design, of course!
