Well, this is not correct. Zodiak-8, Arsat 55 PC, Volna-3, Vega-28, Calejnar-3, Telear-5 and Arsat 500 APO are multicoated.d Don't forget: Most of the soviet lenses have single layer coating only and tend to flare. There are only a few MC coated lenses on the market.
Unfortunately, your copy of Mir-26 was not properly assembled and adjusted. The Super-Rotator 45 was based on this lens allowing 12mm shift together with 8° tilt without vignetting on 6x4.5 frame.I owned the MIR 45mm because I needed something wider than the 50mm Flektogon. How disappointing! The distortion, contrast and sharpness in the corners were too bad. Never again.
Unlike you, I prefer shooting with a fisheye lens. Once you learn how to properly align the lens with the horizon, you can take pictures without the typical "fisheye effect."The 30mm Arsat/Zodiac fisheye... well, it is heavy, bulky, and I rarely used it. I don't like the fisheye effect at all.
True, the rear filter is the part of lens scheme. There will be no infinity without filter glas.If you want to buy one, take care that the complete filter set is included, especially the UV filter is mandatory. Without an attached rear filter, the lens is not working correctly (focus to infinity, sharpness in the corners).
Calejnar-3 is more compact/less bulky. Unlike Sonnar, it does not have chromatic aberrations in out-of-focus area.For portraits, the 150mm Kaleinar may be interesting. But there is no need if you own the 2.8/180mm CZJ Sonnar.
Any opinion about the Mir 38B 65/3.5 lens?
My Mir-38 is optically good, but mechanically poor, it's the newer design with the rubber focus ring. The helicoil is fine and smooth, but the indicated aperture is off at the open end of the range as the internal aperture cam is miss-shapen. The auto-aperture mechanism is also finicky and not adjustable. The older all metal versions may be better mechanically though. Maybe.Any opinion about the Mir 38B 65/3.5 lens?
I like the Arsat/Zodiak 30mm fisheye: it has a unique perspective that are fun for certain topics.
As far as I know, this is only true if you have the "MC" version. All lenses without "MC" have the single coating. And you will find much more of the single coated lenses at the second hand market than the "MC" lenses.Well, this is not correct. Zodiak-8, Arsat 55 PC, Volna-3, Vega-28, Calejnar-3, Telear-5 and Arsat 500 APO are multicoated.
If you cannot find or adapt a filter, you can re-adjust the infinity stop so it will focus to infinity without the rear filter. This is necessary when you convert it to a Hasselblad mount as the mirror will hit the filter. I have not noticed a change in the aberrations, but I'm sure they are there if you look close enough.I have a Zodiak 30mm fisheye lens, and as everyone says, you absolutely need a rear filter or it won't focus to infinity.

The above listed lenses all have a green reflection on at least one of the lens surfaces, indicating some form of Multi-Coating on that element (I don't have the Arsat 55 or the 500, so I don't know about those). As a general rule, blue and yellow reflections are typically simple coatings, a green reflection is only obtainable by multi coating (as are the deeper blue and orange reflections). Reflections from multi-coated elements are also less (dimmer) than on the single coated surfaces. But not all multi-coating is the same, early multi-coating does not transmit as much light as the current ones, which use more layers. I believe all the above lenses have some multi-coated elements, but nothing like current optics. They have modest T-numbers and do flair.Well, this is not correct. Zodiak-8, Arsat 55 PC, Volna-3, Vega-28, Calejnar-3, Telear-5 and Arsat 500 APO are multicoated.

This is incorrect because the only Zodiak-8 and Calejar-3 lenses were produced without an MC label. All of the other lenses I mentioned are multicoated.As far as I know, this is only true if you have the "MC" version. All lenses without "MC" have the single coating.

I have a Zodiak 30mm fisheye lens, and as everyone says, you absolutely need a rear filter or it won't focus to infinity. The optical path length in glass is different from that in air, so when you have the filter in place, the converging beam comes to a focus a little further back. The filter is about 1.5mm thick glass so the focus offset is about 0.5mm.
I assume that the lens was computed with the filter as part of the optical design (of course), so even if you could use it without the filter, there could be off-axis aberrations, although I don't know how serious they would be.

Incidentally, the multicoating on the Calejnar-3 is just a nice option, not critical at all, unlike the Zodiak-8.
I've seen ik numerous posts something about the Calejnar. I just can't seem to find those lenses online. Can you share a link?

I have and use all 3 of those lenses.
The Arsat/Zodiak 3.5/30mm fisheye is... well the only fisheye you can get in P6. It's good, not as good as the Distagon, but quite reasonable.
Do you mean the F-Distagon lens for Hasselblad cameras? I bought mine on eBay in 'very good' condition for €3,000. How much did you pay for yours?
It is a CFi version from the latest generation with the serial number 89XXXXX. Although the lens is very good corrected for chromatic aberrations on digital sensor, there is still a tiny purple fringe shift at the edges, which can be eliminated by the applying the dedicated lens profile in Phocus software from Hasselblad. In addition, the software can also automatically remove the fisheye effect.Was that a CF version? I don't own a F-Distagon for Hasselblad, but a collector/dealer friend of mine had a C version which he was willing to sell to me (I can't remember what the price was, but it was less than €3,000). I borrowed and tested it for a while, compared it to the Zodiak and Arsat 3.5/30, and decided that for the price and my usage, the Arsat was good enough at 1/10th of the price. But that was before I got more involved with IR photography, so maybe I should reconsider ...
CFi - nice! What size digital sensor are you using, I've mostly used the fisheye with film, as you loose the 180 FoV with digital. If you go out to the corner of 54x54 image, you'll probably find more aberrations with digital.It is a CFi version from the latest generation with the serial number 89XXXXX.
