Yesterday I received a new lens - a very old and cheap 135mm Canon LTM mount lens. At first, my intention was to simply try this focal lens in a cost effective way, sell it and buy an Elmarit. Yesterday, I did a couple of shots, which pleased me quite a bit, but I still had second thoughts. I spend most of the time at my apartment, so I had no chance to shoot it at 1/1000sec and closed down to see how well it would perform.
Today I spend an hour walking with this lens for lunch. When I came back home I was surprised just how sharp the lens actually is. It is at the edge of its sharpness when shooting with Leica M Monochrom 246. It feels that a few more megapixels of the resolution would not resolve any more detail, as I can see slightest hint of blur, almost invisible. Rendering of this lens is very pleasing. It is on a low contrast but produces very pleasant values, which work beautifully with my adjustments in LR. I'd say that I like the source negatives more than from my Zeiss collection. Zeiss has a ton of sharpness at its reserve of course - probably good enough for a 100MP sensor.
The bottom line is I paid $75 for this lens including shipping and Paypal fees. Having said that, I feel like I have stolen a $1000 lens from the Leica Store.
