Here start the image staken with the Biogon 28mm lens.

Thanks Raid.
The images look very good from what I can see.
Man, I really want one of that 45mm...

These are snapshots and no more. I used PS.

This is it for today.

While using a color film is good to show Zeiss glass image colors, I may use B&W film for controlled lens comparisons tomorrow. What do you think?

The 45mm lens is awesome on either a 35mm M camera or the M8 where it would be more a short tele lens. The 28mm Biogon would be close to a 35mm lens on the M8 while being a wider lens on film cameras.

What do you think?

Honestly? These images are rather too poor -- in terms of exposure, choice of subject, realization of scanning and post-processing -- to provide anything meaningful about these lenses. Highlights are washed out in several of them; shadows are blocked up in others.

Anyone who'd evaluate a lens based on these shots would be satisfied even with a 43mm-86mm Nikkor and drugstore-processed prints. I'm afraid that's what these shots look like.

Honesty is welcome. I get your point. On the other hand, these are snapshots with the lenses, and I have stated so. The lens comparison is not yet done. I will do it today. I just wanted to see what the feel was when using these two lenses. I commented about it in the earlier part of this thread. Thanks.

The posted images were taken in direct sunlight at the water. This is what some people may experience when taking photos. The elements were not controlled.

I will in the next round of lens try-outs keep larger image files for all lenses. Maybe this will be better for inspection of images.

I just finished a run of shots with:

1.Planar 45mm 2.0 G/M

2. Canon 50mm 1.4

3. Canon 50mm 1.5

4. Summicron-C 40mm 2.0


The other run was :

1. Biogon 28mm 2.8 G/M

2. Rokkor-M 28mm 2.8

3. Kobalux 28mm 3.5

I used Kodak C-41 film. I stabilized the camera on a heavy Gitzo tripod, and I used a cable release cord.

I hope to have soon results posted.

Raid, are you going to do controlled testing for bokeh and rendering at different apertures and distance? By controlled, I mean whereby all the factors are identical except for the lens? (Same view, tripod, film, focus distance, aperture, exposure, etc.)

Yes I have done such a set-up, and now I need to figure out how/where to upload them in large file sizes. Few free website let you upload files exceeding size 1MB.

I will start with photobucket.com until someone advises me of somewhere better.

Is this file too large or is it OK to see ny differences between the lenses and the apetures?

I chose the lit Christmas tree for seeing some bokeh at each chosen aperture. The paper on the left shows you which aperture and which lens was chosen. The focus point is the left edge of the first video tape on the left. I have two black lines drawn vertically there. Any focus errors are due to eyesight and not the lenses. I lef some room on the right for window to show for possible flare.


Is this lens comparison "crappy"? I don't think so.

Here are the images from the Canon 50mm 1.4 LTM. I got it a few months ago from KEH. I have used it only with a couple of rolls so far, but I am confident that it is a sharp lens.

I decided not to move the tripod a lot whenever th focal length changed a little. I just want to illustrate with other lenses how the Planar images look like. I know that the wider lenses will be more challenge by the window light, but there was no direct light entering the room. so I saw it as OK to allow more coverage.
