Hello folks well the hardest part is done and with the Ugly test , Images thread now comes the sharpness test my last test on these lenses and there are some surprising results. i will touch on them as we go along but these lenses do perform. Now in this test you can also look at the contrast, color , saturation and dynamic range of the lenses . Not what I was testing for but it does show that also so may help seeing what you like better or worse. Now the lenses the Summarits are going against are some of Leica's finest lenses and although one lens the 35 cron pre asph version IV is a old lens with a unique look to it but in technical terms of sharpness and such it gets a nice whooping here. LOL But i still love the lens but it shows you what the new technology Leica did on the Summarits does over the old glass. Pretty interesting as you will see and you will also see why the 50 Lux ASPH is considered the best 50mm on the planet and again it does not disapoint for one second. Interesting is the 90 cron APO against the new 90 Summarit and i will explain that one when I hit he 90mm but this one has me baffled a little. I checked before actually starting the test the focus on each lens made sure it was dead on in the LCD and tweaked as needed, well either the 90 summarit is the gold standard or I missed on the 90 cron and you will see that but it is odd the results.

Now test conditions so everything is clear. Shot around 8 am in the morning in Flagstaff Arizona which is about 7200 ft up and about 25 degrees out. I shot a nice old building with the 3 sets of lenses in somewhat different spots so I had detail for the corners . The 35 I am closer than the 50 and the 90 I moved over to a window as you will see. Shot on a tripod with the self timer set for 2 seconds ISO 160 for the best results. NO WB but brought into 1.3 Lightroom and processed 3 different times with full frame and also center crop and corner crop all done in LR

Now fair WARNING this is a long test and will go into the pages of data but i want to show everything i see so please forgive the long test.

Also please wait until i am finished to post want to try and keep it all together so it is easier to read . I am doing the LUF site and GetDPI site at the same time so i can keep track of what i am posting. This is a bit difficult to do so when i give the go than please go ahead and start posting. Thanks for your understanding.

Lets start with 35mm lenses the 35mm Summarit 2.5 and the 35mm Sumicron version IV pre-asph.
