It's a lot sharper than my copy of this lens, makes me think mine is faulty, that shot of the flower head with ladybird is fantastic!

that's problem with Russian lenses, quality control is not always best one

which photo you like? the original or the crop?

yes, it's a nice little lens, but what i find limiting is the way aperture is set, most of the times i had to look at the lens to set aperture, while usually on other lenses i set aperture without moving my eye from the viewfinder...
also minimum focusing distance is 65cm , i like more 50mm lenses that have shorter minimum focusing distance

The aperture on mine was sticky when I got it and the other day when using it something broke and now the aperture ring just spins uselessly so it's now junk.

All 6 Helios 44s I have are good, but as you say, the quality control was patchy in the USSR.

I like both shots, the bokeh on the uncropped one is good. The crop really stands out though, so I prefer that one, very very nice work.

I don't think I'm going to bother getting another I-50, I'm going to get a Pentacon 2.4/50 pancake instead, not much larger.

well they are really cheap, so it shouldn't set you back financially to get another at some point...

Very true, they are the second most common lens to see secondhand after the Helios-44 and just as cheap.

Your pics are good enough to make me think another I-50 wouldn't be a bad thing...

Nice pics. Thanks for sharing.

The lens is very good. I didn't use it. But should like to do.

Good contrast and resolution power. Good 3D.

It seems to be very useful like a macro lens, using a short tube.

Rino.

Be interesting to compare it to the CZJ 2.8/50 Tessar...

Wich version of the tessar?

Good job to do, isn't it?

I'm impressed with its IQ !
Contrast, colours and sharpness are very good.

The one in the pic is not mine Razz

I've got my exakta alum one for ~35 euros some years ago and just won some days ago a m42 chrome-alum version of it for 45 euros... so you can buy one easily and cheaply Wink

Search the Mflenses archive for this lens .... you might be surprised about it and it's 3D capabilities Wink
