I made some lens tests

[Jo Geier]

HI, I started to collect some vintage and modern LF lenses as I didn't knew which kind of I actually wanted so I got a few and made a digital "test" with them.
I don't know if this against some rules of this forum because I just put my Panasonic GH2 behind my Sinar P2 and put one lens in front.
I always took one image wide open, all of one "model", my 4x5" Cham.

So, I will just post the images here with the lens name above.
No image is sharpened or softened, not photoshoped.
Maybe I added some light but no contrast.
This is NO professional test.

I like this one. I suspect much of the softness with the Ernemann projection lens is lack of flocking inside the lens, you're getting flare from the barrel?

Since aperture influences the look of the image, you might find it instructive to share that information too.

It's good that the Sinar is on a tripod, but if the digital camera with with you made these images was not, then your images may not consistent.

The fewer the variables we introduce when testing, the better.

Dear Ken,
the camera is directly mounted on the P2 so no other tripod is needed.
As mentioned in the firts post all images are taken with aperture fully open.
