MarkP Posted July 9, 2011 Share #61 Posted July 9, 2011 Advertisement (gone after registration) Dirk just emailed me back: "Try locking it into place with some more force, then it will stay in place when you turn the aperture. You'll need a Leica threaded 19mm filter. Otherwise your B+W will soon be lost. Dirk" It works. The lens now does not unlock when turning the aperture ring if initially locked in tighter when extended. Mark ps: I'll post some comparisons with the current 35 Summilux ASPH when the Perar is back.

JapanExposures Posted July 12, 2011 Share #62 Posted July 12, 2011 The vignetting at f3.5 is massive on the M9 ... This is "massive" vignetting on a Leica M9. The Perar has, like most shorter lenses, some falloff at the edges which usually goes away with coding or choosing a lens in the camera settings, or of course in post.

tdtaylor Posted July 12, 2011 Share #63 Posted July 12, 2011 Please bear with me. I coded the lens for the Summarit 2.5, and it comes up unrecognized. Note that I have always used Auto. When I went to select it manually, I see three 1.4's and two 2.0's but no Summarit. I am on the latest software. Am I missing anything (just checked it again- 5 35s, no Summarit). PS- here's the code table I was using: http://whimster-photography.com/leica_m_lens_codes/index.html Link to post Share on other sites More sharing options...
wlaidlaw Posted July 12, 2011 Share #64 Posted July 12, 2011 Terry, Reading clockwise, a 35 Summarit should read BWBWBB. The 35 Summarit does not show up on manual as no uncoded modern Summarits were ever sold, so no need to manually code. I would manually select as a pre-asph 35 11310 Summicron and I doubt if you will be a country mile out. You are not going to get enough vignetting correction whatever you do but that may be one of the charms of the lens. Wilson Link to post Share on other sites More sharing options...
UliWer Posted July 12, 2011 Share #65 Posted July 12, 2011 Today I fetched my new Perar from the customs office - first new non-Leica lens since I sold some Minolta MD lenses more than 10 years ago. The Perar seemed attractive as it goes back to the original triplet-idea. First impressions: To unscrew the tiny rear cap and the even smaller front cap takes ages and you need fingernails to get hold of them. Where to put them to avoid losses? In the wallet. I can't imagine a quick change of this lens other than leaving the glass unprotected in a bag which is much too big for this lens. How to apply the hood? The obvious way would be with the bigger opening posing forward - this does not work, the other way round works (with lots of screwing) - but won't this cause vignetting? No it doesn't. So the miniature hood against which the ridiculously small one of the Berg-Elmar looks really adult seems to be quite clever and effective. Everything is small and short with this lens. The focus throw from infinity to 0.8 m is less than a quarter turn; the distance between apertures are a few millimeters. No clicks for f-stops, the maximum seems to be anywhere at f/1.4 - though if you look at the front of the lens, there is no difference between f/3.5 and this maximum position where you can set the aperture ring. They didn't promise anything more than 1:3.5. There is a red dot of microscopic size to show you where to start mounting it in the bayonet. It works easily. The usual click and the right frames for 35mm show. I had no problems fixing the extended lens like I am used to do with Leitz collapsible lenses. No special force needed. Though it's true that the lens doesn't stay stabile in the retracted position - all collapsible Leitz/Leica lenses I know are much more "sticky" and so more stabile in their "sleeping position". Somebody mentioned "massive" vignetting. If you turn the lens detection off there is obvious vignetting and some colour shift in the corners: Welcome, dear visitor!

With the manual lens setting of the M9 I'd recommend the version IV 35mm Summicron (11310/11311) as this lens also shows considerable vignetting. Then it looks like this: (The new firmware seems to work effectively - the ugly spots are on the object I took the photos from, neither on the lens nor on the sensor...)

UliWer Posted July 12, 2011 Share #66 Posted July 12, 2011 Now some unscientific comparisons. The obvious contender is the 1:3.5/3.5cm Elmar - as it is also a triplet design - though more than eighty years older than the Perar (i used one of the last produced post-war examples which is already coated) . The other one is the 1.3.5/3.5cm Summaron, from the mid-fifties. All at f/3.5, manual lens detection: 2/35mm Summicron (pre.asph); distance approx. 1.50m: Elmar: Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! Summaron: Perar: Most obvious difference: both old Leitz lenses show much more veiling flare (I think due to traces of usage on the glass); the Perar seems to be rock solid against it.

JapanExposures Posted July 13, 2011 Share #68 Posted July 13, 2011 Great comparison. The Perar has the edge in terms of sharpness, contrast and color. Would be interesting to see crops from the edges/corners, can you post some? Link to post Share on other sites More sharing options...
wlaidlaw Posted July 13, 2011 Share #69 Posted July 13, 2011 I would love to see some comparisons between the Perar, a CV Color Skopar PII 35 and the Zeiss Compact Biogon 35, as these are the lenses I am considering choosing between and in price/size the closest competitors to the Perar. You could include the 35 Summarit but it is close to double the price of the Biogon or Perar and three times the price of the Skopar. I am currently using a Biogon 25 as my compact travel lens but it is just a tad too wide and I would like a small, not too expensive 35 instead. My chrome 35 ASPH Summilux is a bit of a lump to heave around and the other alternative, my V2 28-35-50 Tri Elmar is quite long with its inverted petal hood.

wlaidlaw Posted July 13, 2011 Share #71 Posted July 13, 2011 Jim, Is that on the Roaring Camp Railroad? One of the places on my list to visit next time I am on the West Coast USA. That is the remains of a fair sized lathe, I would assume used at one time for turning locomotive wheels. What attribute are you hoping the tune up will improve.

jimcollum Posted July 13, 2011 Share #72 Posted July 13, 2011 that's the place. It's just down the street from where i live. my email is collum@gmail.com... look me up if you make it out here (i have permission to venture thru the junk yard, and usually shoot there just after the sun rises.) there was a problem with my lens in the way it extends/retracts that Dirk is going to fix. Just a mechanical issue.. Optically, I've been very happy with the lens so far.. on the M8 & on film (this is a shot from the other morning with the M6 , Perar & Ektar 100 film Jim, Is that on the Roaring Camp Railroad?

stephan_w Posted July 14, 2011 Share #76 Posted July 14, 2011 can someone tell me how this lens compares to a Summicron asph? I got mine (Perar 2) and I'm not sure what to say.

JapanExposures Posted July 15, 2011 Share #78 Posted July 15, 2011 "The LEICA 35mm f/2 ASPH is about as close to perfect as you can get. It's always sharp, even wide open, even in the corners, at any distance." Ken Rockwell. If you like him or not, but the 35 cron Asph made since the late 1990s is widely considered "the best" 35mm lens there is. The Perar is a triplet type lens. Triplet means three single lens elements. One could say it is a very simple design with many advantages to produce, thus the proliferation in compact cameras of the past. The Cooke triplet is simplest optical design that is capable of correcting all of the seven Seidel aberrations over a wide field of view developed by H. Dennis Taylor in 1893. Where do you want to start comparing the two? Link to post Share on other sites More sharing options...
frank_dernie Posted July 21, 2011 Share #79 Posted July 21, 2011 This is "massive" vignetting on a Leica M9. The Perar has, like most shorter lenses, some falloff at the edges which usually goes away with coding or choosing a lens in the camera settings, or of course in post. PS: this lens is Astro Berlin Tachonar 35mm f1.0 LOL! That is not vignetting it is the wrong format for the lens Dirk! I think the Perar is the only lens I use on my M9 which has enough vignetting to be noticeable straight away on most shots wide open. OTOH it is correctable and the lens is in general nice to use and I am happy to have it. I usually use it at f5.6 Link to post Share on other sites More sharing options...
wlaidlaw Posted July 21, 2011 Share #80 Posted July 21, 2011 I agree with Frank on the Tachonar. Isn't this a cine lens designed to cover an 18 x 24mm frame? I have never had any success messing around with cine lenses, even on the 1.3 crop M8. They always seem so cheap and fast, there is a real temptation to buy them but my advice in general is safe yourself the disappointment. The other issue is the very fast wides sometimes are not in standard Arri or Cooke mount and have a very short back focal distance, so it can be difficult to mount them close enough to the imaging medium. It is not something I am going to waste time and money on again. Wilson Link to post Share on other sites More sharing options...
