How it all begun

Well, I got a used DSLR a few years ago. A Konica Minolta Dynax 5D. A whopping 6Mpixel sensor with built in image stabilization. I really liked it, but there was the earlier monster version of the same camera the KM Dynax 7D that I switched to after some time. Probably still the best DSLR ever to surface in terms of user interface and ergonomics. It had external buttons, switches and wheels for EVERYTHING. You didn't have to use the display menu for weeks and all buttons were placed so it could be operated without taking it away from eye level. The grip was very comfy and it felt solid, unfortunately there was a quality problem with the shutter. But Konica-Minolta exchanged it free of charge after the warranty period, that is great customer service by the way. The camera was a perfect tool to learn the craftsmanship of photography for a rookie as me. I actually got a little bit scared of all the buttons initially, but learning one at a time really boosted my know-how in photo technique. For it's age the display was awesome, large and with high resolution that could be used for critical evaluation in field, the viewfinder was way better than the CANIKON could offer in the prosumer segment. It was of course very expensive as new, but really ahead of its time. At the time I got it some years later, it could be had for less than 250 Euro on the used market which was a real steal. And the low 6Mpixels was no issue at that time when the new DSLRs only could offer 8-10 Mpixels, which is not a big difference in actual resolution.

A friend of mine had a very nice full frame Canon 5D at the time and he used only fast primes with it. When trying his gear I realized what photography should feel like. No more plastic! So I got instantly bored with my flimsy kit lens and wanted primes also. Luckily I had the extraordinary viewfinder in the KM D7D that made it possible with manual focusing on the smaller APS-C format without the aid of microprisms and split matte screens. KM used a traditional pentaprism where the rest had cheaper and duller pentamirrors, so the VF was large and very bright. This quality has been kept after Sony's takeover and A700, A850 and A900 have all had market leading pentaprism viewfinders for you to enjoy.

Back to the story, My budget didn't allow the expensive fast prime lenses with autofocus and not the high end vintage manual ones either such as Leitz or Carl Zeiss. Also the Minolta AF mount in the camera didn't allow adapters for anything else than M42 lenses without corrective optics. At that time a C/Y Carl Zeiss could be had at a very low price and could easily be used on Canon cameras with an adapter. Unfortunately when I joined the manual lens arena the global interest had already exploded and it was no longer possible to make any bargains.

So I started searching the web for cheap and high performing vintage manual lenses in M42 mount that was simple to adapt to the Minolta AF mount. And after hanging around at forums such as the alternative selection of Fred Miranda, Flickr and MF lenses. I realized that the Russian lenses for the Zenit cameras was exactly what I was looking for. They were common, cheap, sharp, and had a wonderful character, especially in terms of bokeh (background blur rendering) and color reproduction. Most of the lenses were clones on the eastern Carl Zeiss designs that was made possible when USSR took charge over eastern germany after WW2.

The lenses I instantly went after was the Helios 44 (58/2) and Jupiter 9 (85/2). The Helios lens is a Zeiss Biogon clone and the Jupiter is a pre war Zeiss Sonnar clone. The Russian engineers have then let the development continue over the years and released updates and changes to the original concept.
At this time I started remembering my fathers camera gear that he had in the late 70-th. I remembered there were some shiny odd looking lenses and they were from the USSR. So I asked him what it was and I got a pleasant surprise when he went down to the basement and rumbled around in the since long forgotten camera bag. There was a beaten up Helios 44 and a nice looking Jupiter 9. Yeay dad, you have great taste!

Anecdote:
By accident, dad had backed over his camera with the car !!! So the focusing ring on the Helios was a little bit loose, but fully functional. Optically still perfect. The Zenit camera got some scratches on the body, but other than that it didn't bother over the deep tissue massage and worked flawlessly. Solid stuff indeed.

Unfortunately the lenses had M39 mounts for SLR, so I had to find a thread insert that converted the M42 adapter to allow 39mm threads without changing the infinity focusing ability. That took some months, but finally I found what I was after on the Bay for a few cents. The Jupiter lens had an iris fault and dad inserted a fixed aperture around f/4. Other that that is is almost in mint condition despite its age.

So here they are accompanied with the modern Helios-44M-4 that I no longer have in my possession.

The old lenses have really low serial numbers and there is a small chance that they are manufactured by Carl Zeiss staff in the German production line under Russian control. I have yet not checked the exact year of manufacture, but I think they are from the late 50-th or perhaps early 60-th. The odd looking symbol on the Helios says that they are from the KMZ factory. Several other factories have made the Helios lenses such as BelOMO, Valdai and MMZ see this link for logos. The Jupiter is made by LZOS.

The old Helios has a 13-blade iris and has a wonderful bokeh. Edge sharpness is perhaps its greatest weakness. Against the sun performance is also not of highest standard due to the simple coating techniques that time could offer. Center sharpness is very high and the out of focus highlights are buttery smooth. Ok, some image samples with the old lenses.

I was now on the track of real photography. As you can see, the fast vintage lenses could easily offer a shallow depth of field with nice and creamy background blur rendering, even on the smaller APS-C sensor size. Something a slow kit zoom has very difficult to offer no matter how sharp it is.
So thanks to dad, I got a new hobby.

I just had to show the Vega-12b lens and try the iPhone blog app. Quite small for being a medium format lens. I'm glad that I got it for free due to the sticky aperture, which I have mended to a usable, but not perfect state. Although it is a very cheap lens on the used market. Being a medium format lens, it could be useful as a cheap way into DIY tilt-shift assemblies on APS-C and full format DSLRs.
Vega-12b

Photo nerd facts:
In a tilt shift assembly one can play with perspective corrections, by shifting the lens position by radial translation, and also putting the focal plane in any direction by angular rotation of the optical axle.

By shifting the lens, the perspective distortion is corrected to have straight vertical lines of the buildings.

By tilting the lens, the focal plane is put vertically along the stone wall instead of the normal horizontal plane that is always had with a standard mounted lens.

There is also a fake way of producing images that looks like shifted photos by applying gradual blur in different steps along with high color saturation and contrast. This is my first try I made several years ago, it is not perfect but at least gives some illusion of being a miniature world. Fake focal plane following the road diagonally across the image.

Yesterday morning when going to work I stopped at this sight and waited a few minutes for the sunrise.

Cranes Vega-12b


On the camera sat a Vega-12b 2.8/90 that I got for free by a nice Russian fellow since the aperture had stuck wide open. I succeeded to mend it to some degree without having to perform deep lens surgery to clean the blades from oil. Now it is working but tends to stick if it is left wide open for some time.

Lens nerd facts:
The mechanism of this lens can always open the iris by turning the aperture ring. So a good recommendation is to store the lens stopped down since most Vega-12b lenses will develop sticky aperture sooner or later due to internal grease migration.
Normally they can be had for less than 30 Euro on the Bay.
The lens is actually a medium format lens for the Kiev-60 cameras that has the same mount as Pentacon six. This mount is easily adapted for any modern SLR or DSLR since the register distance (distance between film plane and lens mount) is longer on a medium format camera. Thus the ability to focus to infinity shall be kept if the adapter has the right thickness. for more information regarding Pentacon Six and Kiev-60 have a look at http://www.pentaconsix.com/RussUkrdata.htm
Hello world

This blog will focus on really low budget retro camera lenses with high IQ used with modern digital cameras.
Perhaps there will be some lenses with retrofocus design also as the blog name may suggest.

Other that that general tips and tricks and hands on DIY projects will be presented for you that also like to keep the camera budget at a nano level but still eager for high quality results. The topics will not only be related to photography although it is the main topic.

I hope you'll stay tuned for more.
