Thank you! I live for the morning light here. It's always wonderful.

This is one of those same buildings seven years ago, with another copy of the Jupiter 8. This one's glass is super scratched up, but I'm not complaining for the price. It's a mood lens.



These buildings have an open floor plan. Even completed, you can still see the sun shining through them if you're positioned right. Hmm, I guess I need to get a picture of that next.

I'm sorry now that I've passed on scratched lenses on ebay. So many lenses sold as is for parts with hardly anything wrong with them. Never knew a scratched lens could perform so well!

I think most people greatly overestimate how much lens flaws will affect an image. When I say "super scratched up," I mean the whole front element is covered in scratches, like someone tried to "clean" it with sandpaper. A single scratch, even a deep one, you will not ever notice. It takes a lot of scratches, or dust, or fungus, to scatter the light enough to reduce contrast. And that is the only consequence, reduced contrast. Sharpness is not affected.

My scratched Jupiter 8 blooms around any bright lights in the frame, regardless of aperture. It's kind of a cool effect, just not one I want all the time, which is why I splurged on another $25 J-8 which was not so scratched up. Even the better copy does this a little (it is 60 years old, after all), it just doesn't beat you over the head with it. These are with the scratched one.







I did have a lens once (a Cosina) with two of the cemented elements delaminating. Not only did contrast suffer, but any bloom had a purplish color cast compared to the rest of the picture. It just looked bad no matter what I did. So I try to avoid anything with apparent delamination.

That bloom is attractive in these strong sun scenes- what was the camera it was attached to?

Those older pictures are with a Sony A7r, and more recent pictures are with an A9 I bought (used) early this year. Unfortunately, as a rangefinder lens, the Jupiter 8 can only be adapted to cameras with short flange-to-sensor distances. The ability to use old rangefinder lenses was one reason I got into mirrorless years ago.

After a play with one, I've picked up and just cleaned a little Industar 50 2. Quite like and look forward to exploring more.

That is an incredibly pleasing gear combo. Makes me wish my new K3iii was a fun g-shock colour.

I like the movement the last two images capture- the repeating flowers creates an path to my eye through them.

Another Helios 44, an early silver version. My copy was apparently made for export, engraved with the words "Made in USSR" in plain English. Still, the seller I bought it from eight years ago was in Ukraine.
