The version with goggles had a longer production run until 1973. In outdoor photography the lens really shines when used slightly stopped down. Depending on your purposes it might still be a workable combination. While it's not a great picture it does demonstrate the ability of this lens under challenging lighting conditions. Each human eye individually has anywhere from a 120° to 200° angle of view, but focuses only in the center. These lenses had 8 elements and provided excellent resolution, but contrast was middle of the road.
I love to see people breaking from the norm with their gear. So, to answer your question, I find the differences more noticeable on the M 240. However, the larger the sensor resolution, the less one will notice small 'degradation'. I would prefer to call it a difference in fingerprint or characteris- tic of image rendering. And it looks stunning with the classic paint, too.
The first version is very soft wide open. An endless production run spanning over half a century and loads of important pictures taken with this lens is enough to prove that the Summicron can rightly be consider as the 35mm Leica lens par excellence. As such, it is easier to use for most, when capturing a group shot. Most of these lenses were manufactured in Canada. I hope no one misunderstands me because I loved using my M9.
This may be the result of coma or comatic aberration. Thank you too for reading through it all. As far as I know, there is just one version of the collapsible screw mount Summicron. With the square rectangular hood on the lens, the camera is always ready to shoot. It won't replace my Summicron but it's good to see others get a chance to buy some more affordable glass for their systems if they don't want to invest in Leica glass. Very few available from new, but second-hand you have a good chance finding one of the metal hoods.
But if I come across one I'll pick it up for sure just to see if I like it. It has been a daily user since it was handed down to me over twenty years ago. The last lens is the only one I have now. Though what that means is each newer version is optically better than each previous version. Because of the reasonable depth of field even at wide open aperture, there is some room for focusing error. Photobucket sends ads instead of embedding photos from their free galleries. This is used in tele lenese lenes where blurring motion of the camera from inevitable vibrations are adjusted by the lens.
There is some play in the aperture ring but it is by no means loose, and is supposed to be normal. As to those who want to buy it now. Having fun with the Leica M9 and my daughter. Oh--and the ring came loose on me in Prague or Budapest many years ago. This third version of the Summicron still had 6 elements but slightly larger optical elements and the protruding aperture control lever was removed. Two versions - one with a convex focus tab, the other a concave tab see images below.
I'd leave that for you to decide. Expect to pay 20% more directly from a dealer. Johannes Kepler mentions Camera Obscura in 1604. In fact, the solidity makes it feel like it was made out of a solid block of metal. Depth of Field: The trees and buildings in the background is very much out of focus, and the handrail you can see behind, in the bottom of this photo is slightly out of focus. I just thought to rant a little about this lens.
For photographers who are on the move a lot the Summicron 35 is certainly one of the most effective wide angle lenses available. It shows a ton of wear and I tell everybody that but then they ask me to sell it again. Leica offered to replace it, but I preferred to keep it as is not for collector reasons. The closer you get to something, the 'more' bokeh' you get in that the focus becomes less for the background and foreground at close distances than at long distances. Look at how the car just pops out of the page.
