M42 Adapters to A-Mount

If you followed my last blog posts on using inexpensive lenses like the Carl Zeiss Jena 35 on my A99V you might have been wondering on how to make it fit.  The way you pull this off is with a M42 to A-mount adapter. The adapters is fairly inexpensive, ranging from a flat piece of thin piece of metal with a Sony/Minolta A-mount bayonet fitting and a threaded opening for a M42 lens to .. yes the same with confirmation chip glued to them.

The benefit of using the slightly more expensive chipped versions is that the confirmation chip communicates with the camera, telling it that there is a real Sony lens attached. The camera then reads the information from the chip, and applies this knowledge when it determine how to react. The direct effect is that camera will let you use Aperture Priority automatic exposure, so you can select the aperture and the camera will select an appropriate shutter speed. The draw back is that you cannot just use any chipped adapter with any particular lens. The chips information on focal length has to correspond with the lens focal length and f/stop. That’s why I usually end up using a cheap non-chipped adapter, where I can use any M42 lens.

I got 5 different adapters, and each just slightly different in thickness. The cheaper versions has no chip but to be honest it is not the chipped I prefer. You might also be able to see that one of my adapters was a few thousands of an inch to thick. Causing the lens to move too far away from the focal plane, with the loss of infinity focus as an result. The problem got solved by sanding the adapter until it brought the lens close enough to the sensor to focus at infinity. My Chipped Lenses tells the camera that a 50mm f/1.7 lens is attached to it, only problem that its rarely the case.

The adapter attaches neatly to the camera, and is almost invisible once the lens is attached.

Your are about to step into a world of inexpensive, high quality M42 optics. Lenses for this mount has been produced for more than 70 years. There is communities on Facebook that offers clean and restoration of lenses if needed. All it takes is that you are willing to forget modern convenience, become a better photographer by mastering your camera in total manual mode and forcing yourself to think carefully about each frame.

Word of warning

Be very careful when selecting a lens, even though T mount lenses also is 42mm, is not the same, forcing it can result in damage to either the lens or the adapter.

Some lenses has a aperture pin which comes dangerously close to the mirror or connector pins in the A-Mount. On any account this pen has to be pushed down since the aperture control won’t work unless the aperture pin is pressed. For me the solution has to super glue this pin.

 

 

HVIS JEG KUN MÅTTE EJE DET ENE OBJEKTIV (Danish)

Samyang 85mm f/1.4 versus Volna-3 80mm f/2.8.

Hvis jeg KUN måtte eje det ene af disse to objektiver, så havde jeg haft et meget svært valg at træffe.

Jeg sidder og kigger kærligt på mine 2 nyeste erhvervelser, et full frame objektiv Samyang 85mm f/1.4 til Sony A-Mount kamera og et mellemformat Volna-3 80mm f/2.8 til Kiev 88 systemkamera.  Jeg skulle egentlig kun købe et Samyang objektivet af en ven, men gik derfra med begge disse dejlige juveler…

Egentlig havde jeg ikke de helt store forventninger til russeren, da mit kamera er et spejlløst Sony A6000 med en lille crop sensor, så  min forventning var nok at et objektiv til fullframe skulle fungerer fint –  Men et mellemformat objektiv på et kamera med crop sensor – det vil næppe levere kvalitet .

Forskellen på formaterne er jo enorm. Et mellemformat objektiv vinkler lyset /motivet ind i en anden vinkel og det bliver fordelt over en helt anden større flade, så derfor må der jo gå en masse information tabt. Et optik bygget til min kameras sensor størrelse har den korrekte vinkel og samler alt information indenfor den korrekte dimension, så alt logik siger mig at dette eksperiment vil gå galt.

For nogle foto entusiaster er drømmen at have et smukt perfekt sæt af ny indkøbt kamera og objektiv. –  Alt i perfekt stand, kosmetisk i tip top stand og med markedets bedste specifikationer man kan opnå.

Sådan har jeg det ikke… mine mest skattede objektiver har set bedre dage. – en bule i filterringen, malingen slidt af på kanterne og med misfarvning af glasset , dårlig eller næsten ingen coating. med flares og andre unoder som resultat.

Jeg elsker dem som et par yndlings jeans, der er fantastisk at gå i, men er på nippet til at gå helt i stykker efter mange gange vask og slidtage…

Derfor måtte jeg straks finde en DIY løsning – altså en gør det selv løsning – for at montere Kiev 88 objektivet på Sony kameraet. Så den køreklare Samyang måtte pænt stå i kø og vente på opmærksomhed.

– en lang historie gjort kort, så blev løsningen en helicoid m42 – NEX adapter, som kan varieres i længde og den korrekte afstand til sensor kan opnåes

Til manges skræk og rædsel så bruger jeg en ofte stor limpistol til at samle med – men bare roligt, intet bliver ødelagt og limen kan fjernes helt igen

Voila, med stor forsigtighed og lidt flid og erfaring, så sidder det hele sammen nu… OG SIKKE EN OVERRASKELSE … Volna optikken og Sony kameraet har et kærlighedsforhold uden lige, en vild flirt og romantik i luften, sikke et par…

Volna laver de dejligste fotos, alt gør det godt : skarpheden, farverne og baggrundssløringen , ja og især bokeh er vild, det bobler og blinker, så jeg selv bobler indeni af begejstring…

I de næste dage så zigzagger jeg imellem at lade Samyang 85 1.5 og Volna 80 2.8 danse kinddans med kameraet på tur. Hvem skal det være ? Hvem danner par ?

GISP      Hvis jeg kun måtte eje det ene, hvilket skulle det så blive ?

Heldigvis gælder samme etiske regler  ikke for objektiver, som det gør i et menneskes kærlighedsliv. Mit kamera behøver ikke leve i et monogamt forhold til ét objektiv. – Jalousi eksisterer ikke iblandt fotoudstyr. – Så begge optikker bliver i min ejendom..

Samyang er lysstærk –  skarp som en kniv på selv 1.4 –  gode farver og klar kontrast – Modlys håndteres tilfredsstillende og baggrunden sløres rigtig flot og der er pæne bokeh bobler. En rigtig fin og sikker arbejdshest.
Volna, kære Volna.. du er en forførerinde – okay, kun blænde 2.8 som maksimalt  – jo jo  – god skarphed, ikke for skarp og ikke for blød. Den rigtige balance – farverne er gode ogmættet, som en god fyldig vin, masser af gode kvaliteter, uden af være grelle eller for dunkle. Baggrunden sløres smukt og fint, så den kan matches enhver moderne optik .

Volna laver bokeh bobler, jeg elsker bokeh boblerne, og de kommer frem, uden at jeg skal knokle og arbejde hårdt med afstande og vinkler, ja, så kommer de dansende imellem træernes blade eller på refleksioner i græs og blomster ,  de popper frem i gadelamper og billygter,  i drikkeglas og blanke flader på bestik…  det er en perfekt miks af pentacons objektivers vilde bokeh bobler og tilsat en knivspids af de klare og luftige bokeh ringe fra en trioplan .  Enhver fotonørd vil glædes over denne lækre Volna – en sand gourmet ret af visuel oplevelse.

Er jeg forelsket i denne Volna. det kan I bande på! mit gamle nørd hjerte banker hektisk som en nyforelsket ungersvend

Ovenfor   Disse fotos er taget på nærgrænsen for samyang 85 1.5, som havde den dårligste nærgrænse. Begge foto er  med samme iso, hvidbalance og lukketid og på blænde 2.8, for at kunne sammenligne og vurdere om blænde 2.8 på et mellemformat optik og et fullframe optik giver identiske resultater på et kamera med crop sensor.   – Bemærk hvor kraftig kontrast imellem lyse og mørke områder er på Samyang, imens Volna mere gavmild deler ud af informationer og detaljer i de mørkere områder, en slags naturlig hdr billede i light udgave, – tak Volna..  Værsgo, drag dine egne konklusioner om sammenligningen

Nedenfor Igen er der stor forskel på skyggeområderne, jeg synes at der forskel på dybdeskarpheden på de to fotos, tiltrods for identisk opstilling og indstillinger. Volna vinder denne sammenligning efter min ydmyge mening.

Zodiak-8B on A-Mount

addling down on the same interesting stream usually leads to exciting new waters. Last week I posted a blog on my Tayir 33, a wonderful 300mm Russian lens, brought to renewed life on my Sony Alpha A99V. This week I am going wide, focusing on the Zodiak-8B, a 30mm lens which equals 16mm focal length in 35mm format.

The first glance at this beast tells you that we are dealing with an impressive piece of glass here, weighing in at 1kg of pure evil  glass and iron, and without doubt one of the best constructed lenses from the Arsenal factories.

Three lenses almost the same, but not quite

The Zodiak-8B, MC Arsat and the Carl Zeiss 30mm Distagon from Oberkochen for Hasselblad bears a remarkable resemblance, but they are very different from each others. I guess their use drives the outer design,  so it would be difficult for them to look very much apart. Comparing MC Arsat to Zodiak, then the biggest difference is to be found in the coating. Zodiak is single coated, where MC Arsat is multi coated. It seems clear that the MC Arsat in many respects, from the coating to the rear cap is an improved design. Comparing the diagrams between the Arsenal Zodiak/Arsat to the Carl Zeiss 30mm Distagon also shows a big difference in lens design, the Russians did not simply copy the West German Zeiss Design

Studying distortion and sharpness frame to frame, then it is clear to me that Carl Zeiss Distagon outperforms both Arsat and Zodiak on both parameters. The question does it outperform it sufficiently to justify the price difference as well? There is a huge difference in price between the Carl Zeiss (ranging from 2000-6000 usd) and the Arsat/Zodiak (200-400 usd). To me, I wouldn’t spend the extra cash to gain this small advantage.

Shallow DOF and beautiful Bokeh

One of the trees i love most in my garden is a Chilean tree an Araucaria araucana. The leaves are thick, tough, and scale-like, triangular, broad at the base, and with sharp edges and tips. My wife might think I adore the tree, but in reality they are great for testing lenses.  This shot was late in the day, overcast, and really close up with shallow DOF. the Bokeh formes nicely and with round textures.

Backlit

Very few objects is so captivating as a deflowered dandelion awaiting it seeds to be carried away by wind. I took this photo quite close, backlit and handheld with the intention to see how well the lens would handle flairs. You can see bubbles forming to the right, I was surprised I didn’t get more of them, given the reflecting light.

Filters

It is clearly impossible to attach filters to the front of a fish-eye lens without cutting off the edges of the frame.  The genius of this lens is that the filters is situated within/behind the lens.  I would have loved if Samyang had shown same ingenuity with their 14mm. The lens comes with 4 light filters: blue, orange, green-yellow and the fourth neutral (protective, already mounted on the lens); front and rear cap; protective leather case.

Colors and detail

I love this lens ability to go close. Combined with its sharpness and amazing colours is this really a fun lens to work with.

The quality of the lens is also remarkable, I was surprised to see how sharp it was at all stops

 

300mm f4.5 Tayir-33 lens on A-Mount

The huge price difference between Zeiss lenses and Kiev, Arsenal and other Russian made lenses makes the russian lenses to be an appealing alternative to expensive Zeiss lenses. The downside of Russian lenses is often their quality control. Optically is Russian lenses often fantastically superb, but then they can also be very bad if you get a bad edition.

Tayir-33 is a medium format lens for cameras the hasselblad 1000f/1600f screw mount. You can find other versions for Pentacon Six (usually with a B in their name) or V for Salyut. This blog post is about using this lens on A-Mount Cameras using the adapter I described in my last blog entry. a 300mm Medium format lens on a A-Mount is for practical measurements around 180mm on A-Mount.

I am not going to dive into comparing the lenses head to head, to prove my argument, but simply show you my love for his glass through some snaps ive taken. The absence of colour fringing from the TAIR at all apertures is very impressive. Where other lenses might show problems with fringing when shooting totally open, then the Tair has no restrictions.

The Tayir is not expensive, you will be able to find it at NatCam for 140$, it’s a bargain that yields hours of good photography.

Wow yes, we are talking a beast of a lens. Metal outside, glass within, and the weight confirms that with its 1875 g. I love the zebra design of this lens, and it does look well on the A99V body.
