Congratulations - the Micro Nikkor 4/200mm certainly is an interesting lens. I'm curious to hear what you'll say/write about it, including samples of course!

The Canon nFD 4/200m Macro has quite pronounced CAs, even though its two front lenses are made of LD (not ULD!) glass (especially at shorter distances). Unlike the Nikkor, the Canon also goes to 1:1, but the Nikon is smaller/lighter. Years ago I had two of them, so I sold one in pristine condition for a whopping CHF 77.-- Wink

Both the Pentax-A* 4/200mm Macro ED as well as the Minolta AF 4/200mm APO Macro have ED/AD glass, and they are extremely well corrected (I don't own them, but had the pleasure to test them).

Please excuse the low voltage L.E.D. lighting in the first couple of frames. The brown-cast is the lighting, and not the lens.



at m.f.d. here and wide open.



Shot as above.



This little fox squirrel was perched about 80 feet from the image plane. f8 and ISO 64. The tree branch was swaying in the wind, and I was lucky to get this level of sharpness. Severe crop over 150%~ probably quite close to 200%.



Quite a bit better here- I had about a second and a half to focus at about 8 feet/2 meters. The sparrows have quite hyper movements, and this is another fortunate shot. f8 and ISO 400 for the heavy shade.

I have read reviews of this lens quite a bit over the years. Many find c/a's with it at m.f.d. I will have to look into that later when I can shoot outside under some good light. The same said reviews above laud this lens as an all-around use lens, and I can see why.

The lens it's self is internal focus only. Nothing on the lens rotates, or extends/retracts with focusing actions. With the lens off the camera, there's barely perceptible movement of the rear element- I can just barely see it. That rear element is quite well recessed into the lens body. My particular copy has almost no friction to the focus ring, and takes a bit of getting used to. The depth of focus band on it is extremely narrow, and takes a bit of getting used to. My copy will focus to just slightly past infinity.
Mine is marked 1:2 at m.f.d. in orange.
It cost me 150.00 CA/D, which I consider a good price for it's condition. Other than a little surface dust/grime on the body exterior, the lens came perfect with absolutely clear glass. It is the a/i variant with the earlier "narrow" tripod foot.
It looks like my search for a nice 200 has come to a halt for a while. I'm really liking this one.

Well, those first three images - even though they are 0.6 MP only (600x1000px) are completely unsharp. I really hope your new dream lens isn't that bad ...Laugh 1

In some quick-n-dirty tests I found it's CAs to be on the lower side - not as good as a Nikkor 2.8/180mm ED or a Minolta AF 2.8/200mm APO, but abot as good as it gets with those good "ordinary" 4/200mm from its time (Minolta MC 4/200, Canon nFD 4/200, Nikkor Ai 4/200). Konica AR 4/200 has more CAs though.

Look again. I bet you have seen the inner zoom-like group moving. The rear doublet isn't moving at all. Lens section here: https://www.kenrockwell.com/nikon/images1/200mm-f4/diagram-1200.gif).

Quite remarkably the aperture is behind the last lens - in other words the sensitive aperture mechanism is completely exposed to to dust, humidity and whatever swirls around in the air ... which makes cleaning of the (deeply recessed) rear glass surface quite tricky. Not a good thing!!

Image #3 is still impressive to me- I can count individual hairs in the tail. I may have been pushing my luck more than a little with a 1/250 sec s/s, with all that motion. (Squirrels of this type rarely sit for formal Wink portraiture ) Image size for most of what I show here is 1024 x 683, or as close as I can get the crops to that pixel ratio.

Image #4 has the I/Q that I have been looking for recently.

Very interesting about the internal movements on this one. I'll get a look again under good morning light.

Your link to the K.R. site doesn't work- he has disabled hotlinking to the site for whatever reason.

I haven't seen that one before either. Petri were similar to Miranda (and a few others) in simultaneously selling a secondary lens range to their main offering, usually with a preset aperture mechanism. Over subsequent years the lenses would differ according to the latest available third party lens offerings, leading to a potentially never ending task for a dedicated collector. Because their first SLR was M42 mount, many of the earlier ones were sold in M42 mount, with a Petri adapter if needed. I have 135, 200 and 300mm lenses some of which look to have been made by Tokyo Koki (Tokina) although others I can tell were made by Sun Optical or Itoh Kogaku.


Thank goodness I'm not a dedicated collector of any particular brand! I have an eclectic collection of all sorts of lenses and only recently started looking at Petri. Their lenses seem to be good performers for very little outlay (apart from a few of their early lenses) with a few unique designs.

I guess the preset versions of their lenses were slow sellers. The lens DB quote is the only reference I can find that they ever existed. Even the Petri Wiki page doesn't mention this one: https://w-atwiki-jp.translate.goog/petri/pages/131.html?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-US&_x_tr_pto=wapp[/url]

Make sure take a look at the petri site.

Thank you Calvin.

Like 1 small

I've come across this site during my trip down the Petri rabbit hole!
I linked to their list of interchangeable lenses, most of which I've never seen or heard of.
Shame I don't use Facebook or Twitter or I'd send them a photo of this preset 35/2.8 and they could add it to the list.

Thanks for the heads up on this. Confirmed with a small flashlight at low setting.
I will have to remember to return the aperture to wide open, in an effort to keep the blades clean, and limit the time I have the exposed rear of the lens un-capped.

My first biotar in praktina mount, I dunno what am I gonna do with it, but it came out cheap and everything seems to be working even if it is in a bad shape


At least the camera looks pretty OK to me - after a throogh cleaning it should really shine Wink
The Biotar needs its filter ring repaired, and then it would look acceptabel as well (after cleaning of course).

The Pratina isn't well known, but it's the first ever "system SLR". Historically, that's quite important. And it did have a few additional "firsts":

* one single shutter dial from 1/1000s to 1s which could be turned in any way, and which could be turned either before or after cocking the shutter
* electrical motor drive
* mechanical (spring driven) motor drive
* 17 m film cassette for motor drive (> 400 photos)
* exchangeable viewfinder (prism, waist-level finder, high magnification finder ...)
* built-in additional direct viewfinder for 50mm lenses

My sample of the Praktina has the pentaprism finder and a Tessar 2.8/50mm (well, a "Jena T 2.8/50"). I found it in a pile of 6000 cameras destined for destruction ... later on I got a really nice Sonnar 4/135mm as well, but that's it. Maybe I should tr to get a few more Zeiss/Praktina lenses indeed!

it surprised me the bad shape of the combo but fully working order of it, of course i haven´t tested with film yet, but the sound of this camera is different than so many japanese i have tried (same special as bessamatic maybe, but in a different way) - in fact i have only got it because of the biotar preset , and it came cheap of course (these biotar in a different mount sell for high amount nowadays)

It would definitely need a cleaning, I assume it all goes from the front, this lens doesn't have many reviews neither, and I would need to adapt it to sony

Nothing special as per se (Jupiter 8M and Lomo OKS1-35-1) but the adaptation to LTM M39 is great. Both lenses are adapted using Industar 61LD helicoid. Cost me 40eur (15eur Jupiter 8M and 25eur Lomo), so it was a bit of a bargain. Unfortunately, while Jupiter is in pristine condition, Lomo has nasty scratch on the rear element

I've removed the little screw from the aluminum tube, but won't come out , it might be glued in?!
The focal is 115-120 but cannot see anything moving, so I'm not sure how is this supposed to work

I have found the Jupiter 8M to be a better performer than the Jupiter 8 in all the lenses that I have tried in each configuration.
I don't know why this is, as they are supposed to be essentially the same lens.
I wonder if anyone else has had this experience

They have different types of anti-reflective coating.

Yashica ML 5.6/300mm (the earlier non-compact version).

I already have the Yashica ML 5.6/300mm C (later compact version) - it will be interesting to see how they compare, of course. Usually the compact tele lense have quite a bit more problems than their larger counterparts ...

The two lenses can be seen e. g. at Olypedia:
https://olypedia.de/index.php?title=Datei:ML_300_5.6_alfred.e.jpg

(be aware that the lens section of the ML 5.6/300mm "non-compact" given in the Olypedia webside is wrong, and that the lens section of the ML 5.6/300mm "compact" has a coloring error in the rear element)

#1


Carl Zeiss Sonnar 30cm F/4, the lens is a late 1930's design. In good condition, but some 'T' coating loss on the front element. 77mm filter ring, 18 nicely blacked blades, stops down to F/22. I had to service the aperture, fun times.

#2


I haven't seen this variant. The early silver type are made with chromed brass, this one is alloy. The origin of the lens is of interest. Possibly a wartime, or in the immediate aftermath, lens. The serial number (Nr.834257) makes no sense, lists have this number range around 1927, 11 years before the lens is first seen, and 9 years before we have a Kine Exakta camera to fit it on.

#3


Other possible pointers toward the time period, and whether this is a production release or some kind of prototype, can be seen. The maker has gone to some trouble to inscribe 'Kine Exakta' in the same type font as seen on the actual camera. But didn't bother to give the lens a depth of focus guide like almost every lens has.

#4


The focusing mechanism is not a threaded helicoid but a cam-type double guide, also a possible pointer to the wartime, or immediate following, period. Anyway, interesting.

#1


M.F.D about 4.5m, @ F/8. I missed focus, it's a bit windy outside today.

For it's age, it sure handles color quite well.
Those winds are a bit of a personal bane for me. As soon as the lens cap comes off whatever micro/macro I'm trying, the winds gust absolutely from nowhere.

Thought I was looking at Jimmy Stewart's rig from that early Hitchcock classic... but it isn't the same camera or lens at all.

Interesting lens. It reminds me a bit of the well known "Franken-Sonnars" 1.5/5.8cm. Originally a mystery, they later on were found to be part of an aiming device of German Stuka bombers (which later was converted to LTM and sold as "real Sonnars" even though their perfomance was much lower) ... as far as I remember.

Many details on your lens point towards "non-standard", e. g. the shape of the numbers on the barrel (not like on my Sonnars 4/30cm and 2.8/180), the focusing mechanism (custom made for quick/easy focusing??), and especially the tube connecting the Sonnar lens to the Exacta mount (with the Kine Exacta inscription). Might well be a early post-war conversion from a lens produced for the military (the T coating is a hint in that direction too; it was pretty rare on cicilan lenses during wartime). Bt maybe I'm completely wrong and the real story is something else Wink

Nothing special with this batch except it was extremely cheap (all for 45eur) and in great condition

Sigma Mini Wide II 28mm f2.8 PK mount - very good condition
Porst 135mm f2.8 M42 (Enna Ennalyt) - some weird white material inside (calcium like, not on glass), usable but needs CLA
LDP 135mm f3.5 T2 with MD adapter - I've opened separate thread; cheap, unknown triplet (made by Komura?), perfect condition
Tamron 300mm F5.6 adapt-something M42 - some micro dust inside, focus rubber is loose, needs new or glue

I think this is it for this year, things got a bit out of hand with lots of good deals (100+ lenses in 12 months Smile ), but it was fun.

Hope you guys had interesting and fun year (lens-wise)
