Imprecise Lens Comparison

[Brian Moore]

Yesterday my M42 to EOS adapter arrived. (Thank you @Hamish Gill!)

It was already dark but I tried grabbing a few images using the Canon 7D and a pair of M42 lenses I have:

• 55mm f1.4 Auto Mamiya-Sekor
• 58mm f2 Helios 44-4

These are handheld and it was very dark. The only PP I did was to push the exposure up a bit in Lr.

Although I knew that AF was not possible using the adapter (and these lenses are not AF in any case) a couple of things surprised me a little. It never occurred to me that the LED display would not register the selected aperture. I should have realized that. I guess I just didn't think about it. More importantly, however, at least for a myopic fellow such as myself, focus must be achieved without the aid of a double image to align or a little fresnel patch to smooth.

Anyway, here are a couple of shots. I used a wide open aperture in both cases.

Mamiya-Sekor 55/1.4


Helios (44-4) 58/2

Interesting Brian. I have that Helios and have M42 adapters for the Nex and OM-D This lens works well. Was not sure if I'd get the adaptor Eos for the 5D M2. I think I prefer Mamiya lens shot though.
The lack of aperture recording or any acknowledgement is a pain. I used to write it down after each shot. The OM-D fortunately you can voice record to files and easily get accessed in Bridge.

The 5D does not, does the 7D? I know the 1D series do.

Thank you, Julian. Actually I don't know if the 7D has voice recording. (I don't use the thing much.) I'll check, though. Good idea.
