Pentacon's colors are there.

Good resolution power. Nice contrast for me.

Enjoy!!!

I read mixed things about this lens.
It seems you have a good copy. Smile

I have to test it again...

I got rid of my copy very quick : unsharp, weird "doubled" bokeh. I'm surprised ! (in a good way)

nice images, very sharp and beautiful colors the first one especially. Lovely circular abstraction when the lens is wide open on the rose image, outstanding.

Nice samples! It is clear that you have a good one.
I have two. The first one had an issue with the adapter, I thought at first, no sharp pictures at infinity. So more testing with other adapter and close focus pictures. Colors OK, contrast soso, and never a sharp pic. On a market I couldn't stay away from another one for 3. And that one is a really good lens!
Both look in identical condition. I need the little price tag, still sitting on the last one, to know which one is the good. So you need some luck in purchasing that lens.

This quality control issue is really.. an issue! I loved this pics, even though you didn't mentioned any post-processing other than conversion but having in mind that I may be betting my money on a bad copy in some auction.. bah.

The Pentacon 29/2.8 is not a bad lens as reputation.
I got mine recently. The lens was in bad shape, scratch, dirt and lose base. After cleaning and tighten all screws i can find, still cant do anything about minor scratches, the lens turns out pretty good, better than several 28/2.8 i have.

Unfortunately I've had a couple of copies pass through my hands and neither performed very well, but after looking at these and reading the above comments I'll track another one down to see if that's any better than the previous ones I've owned. Thanks for sharing Very Happy

Your's look like a nice copy. I find my on the soft side.

After cleaning, tighten all screws, incl front element, the lens turns out to be a completely different.

It has a different blur rending on closer out-of-focus area. For longer distance (3+ meters) wide open and one click down is not as sharp as those sharpest, still a bit soft, and I found it difficult to have correct focus at near infinity. Blur rending from wide open to f8 is insignificant.

Posted some sample images on my picasa.
