I look forward to using this lens more, but do wish it was faster.


Glad you got it in such a good shape.

I'm trying to see the lens half full in this case. I really love the results so I'm not going to complain about the max aperture Smile









All this coating thing got me wondering and since I happen to have two copies:

- Primagon 35 f/4.5 V, Exakta mount, serial number: 1826877
- Primagon 35 f/4.5 no-V, Praktina mount, serial number: 2516404 (I have to sell this thing finally Smile )

I decided to see if I can find any differences between these two.



In more modern lenses it's quite easy to spot the coating color and compare two lenses in this regard. In case of Primagon I've found it much more difficult to get any coloring to show up. And when it did, under very bright sunlight, it had a form of really tiny specks. So, I employed science and here is how I did make these specks bigger:


The V one:


The no-V one:



I'm no expert, have no idea if it means a thing, but what appears to be the coating coloring, differs between the lenses. In other words, there may have been some changes introduced between versions. However, both showed the same quantity of color-spots, therefore I guess same elements were coated in both cases... unless my ignorant logic is failing Smile



Also, when I tried with flash-light bounced of the white ceiling:



I have noticed that light tone seems to lean towards the blue in case of the V Primagon.



Unfortunately, during my quest for truth, I discovered THIS on the Exakta copy (the one I use):



I swear I haven't noticed it before, it only showed up under very harsh sunlight. The Praktina copy does seem to be much cleaner:





In addition, when the light comes at the right angle, about a million of small dots appear near the V lens edges and I can't really tell if these are only reflections of some internal stuff or if that's another flaw of the glass






Well, I guess that's what you get being overly curious. Now, instead of staying cheerful about the result, I'm going to be depressed because of these disgusting scratches Crying or Very sad

Yeah - feeling depressed always makes me happy too.
Look at your results - they are wonderful.
All lenses get blemishes over time and with use.
The results are what counts.
Cheer up
OH

try to unscrew the esternal part of the lens, is pretty easy and try go clean, maybe is just some kind of dirt, like my copy was...
But as Oldhand said if I were you I wouldn't be so depressed, just be happy with the results! Wink

Thanks for the cheering up. Probably I should have used more smiley faces since I wasn't entirely serious.

I love the results and that's what matters. As long as I won't notice any image deterioration, I seriously doubt I'll be opening this lens. I have two Tamrons with issues, waiting in line. Judging with my amateurish eyes, even the contrast isn't affected by this scratches. It's just that upon such discovery, you inevitably start being torn by all these mixed feelings.

It's like discovering that your son is an AF guy. Sure you still love him, sure you still see his potential, sure you won't throw him out or sell for parts, but you cease to see him as that perfect someone you thought he was. And if that wasn't enough, you still have this other kid which is clean, neat and with no scratches at all, but you find yourself completely incompatible with him since he only learned to speak this rare Praktina language. And then... before you know it, you get over all of these thing and you keep enjoying what you have Smile

So, everything is fine and I'll overcome the distaste with time and results Wink After all, it's 'only' a $100 lens we're talking about Smile

Time is passing by and I'm still in love with this one Wink

I went for a short trip to the seaside and even though I was in a bit of hurry, I managed to take a few snapshots... some of which were made through the car's window Embarassed

I love the colors, the voluminousness, the textures. It's such a capable piece of glass.
































Ps.: I drove through a very cheerful village, here is what it is called (the first one):



Although, I get the impression it is inhabited entirely by internet trolls Wink
