35mm Surprise

[elmer3.5]

Hi, as usual with a friend of mine we´re making some amateur lens tests.
Very simple ones, on the m8 at User prof. 1, lots of ambient light, same speed same aperture. All in all equivalent shots. 100% crops attached.

The lenses
35mm
Pre aspherical summilux leica
Canon ltm 35mm f1.8
ZM biogon 35mm f2

aperture
All at F4, same distance.

Please try to identify which one is the canon.
To us it was such a surprise to see how the canon stood against much modern and much expensive lenses such as the zm and above all the leica lux 35!

Cheers!

PD: any hint on how making lens tests are welcome 🙂

these jpegs look strongly compressed, better image quality will make it much easier to evaluate a lens =)

Taking a flyer --

first one on the left is Canon -- softness at the top of the frame --

On the other hand, if this was handheld, it adds additional uncertainty to what is the lens contribution and what is due to photographer movement

Yeah I concur with the above. Although just a guess..

I'd say left is canon, center is summilux and the right is the biogon.

Canon!

Canon!

Hi, thank for your interest!

The 35mm Lenses are:

Left) Pre-ashp Summilux
Center) Zeiss Biogon
Right) Canon

The Canon is even a little more angular, crop displays a smaller image compared to Leica and Zeiss lenses.
On the DNG the quality of the canon is even better.

It was a surprise to see how well this lens behaves in shrpness and in contrast!

Cheers!

I would also like to see uncropped pictures in a lens test =)

I'm with Simon, I can't tell the difference with the compression artifacts visible on the images. Save as TIFF not JPG and repost.

JPEG is not inherently a problem. It depends on the compression settings used. At higher quality settings, a JPEG can be indistinguishable from a TIFF file but use much less bandwidth.

There's a very useful analysis of JPEG quality settings here.

Tiffs!

Tiffs!

Hi, changed settings to tiff, hope it helps.

Leica

Zeiss

Canon

All of them at F4, distance 1 metre.

Cheers!

Ohh yes! 0/3!
If you look at the images again after knowing which is which.. then essentially you could say you're seeing the difference of how modern glass renders as opposed to old.

i can't see the difference between lux and biogon but can definitely identify canon with eyes wide shut
