Pen-F Zuiko 38mm F1,8 Lens on Sony A7R

pen-f-38mm1-a09a6822I don’t remember why this lens was still here.  This Olympus Lens

has been in the end of shelf many years.  It was a Olympus Pen-F’s

standard lens though, Pen-F was a half frame camera (24×16) and its

flange-back was 28.95mm, the lens couldn’t have a focus other than

a macro use, I might have had a test of close-up photo on Canon 5D.  

— The funny history of this lens was, on late 80s, one of my friend

photographer who wanted to experiment, “To get a rough-grain soft

image, using a Push development on a Cross-process” = In order to get

rough Grain, he wanted to use even smaller original = hence Half-size. 

—– So, he asked me to make an adapter to use Nikon Lens on a

Pen-F body.  =  I made it out of Nikon close-up ring and a Pen-F

mount from this 38mm lens = So that, this lens lost bottom mount.

= in normal sense, it is an utterly useless junk

—– though, while Googling the Net, I found the people using Pen-F

lens on the Full-frame Sony camera !    (Unlike the lenses for the

Cropped size senser DSLR camera, those Olympus Lenses has

been made to cover (well almost) the full-frame image circle !) 

pen-f-38mm2-001To modify this lens for a Sony E-mount camera, I found a M-39

Leica lens to E-mount adapter has the almost a right size. 

So, I screwed  M-39 ring to the back of Pen-F lens (+ some

adjustment for infinity focus) = = = Voila, Pen-F lens on A7R.

pen-f-38mm3-a09a6830The test shot on general

distance was usable but

not bliliant.

(The lens might have 

sold as a spre parts =

damaged goods)

Still, Close-up photo

was pretty good.

(Photo below, middle)

Though, there isn’t much soft texture (It may be because

the Sony A7R camera or its image process.) (Photo right)


Olympus Pen-F Lens is very small, (In comparison to such as

Nikon lens + adapter on Sony) pretty nice match to the A7R,

so that, I’m quite happy to have this  F1.8  wide-angle lens.
