When Is A Pancake Not So Flat?
When Is A Pancake Not So Flat?
...having a small camera with 45mm pancake lens
Keep in mind that the average SLR>M4/3 adapter adds about 25mm to the length of the lens, so your 45mm pancake won't be so flat on an EP1. Shorter than your average lens, of course, but the adapters do take up space.
The shortest adapters are C-Mount, Leica L/M and Olympus Pen. Leica and Pen adapters are just under 10mm. The Oly Pen lenses are not only short, but fairly small in diameter. An Oly 38/1.8 Pen lens on adapter makes a very nice compact m4/3 shooter.
I'm not sure if the native m4/3 Leica/Panasonic 45/2.8 macro would be shorter than your pancake plus adapter, but the L/P 45/2.8 is an expensive lens, and may lack some of the character of a vintage film lens.
Also don't forget that your effective focal length doubles, so your 45mm pancake becomes a 90mm lens. Lots of folks, myself included, find the lure of legacy lens usage tempered somewhat by the 2x crop factor. Great if you like to shoot longer focal lengths, not great if you like to shoot wider. I use my Pany 20/1.7 lens much more than any of my 35mm+ legacy lenses.
.... the massive 85 f 1.7 should be interesting too!
I find that very large lenses till work fine on m4/3 bodies, just remember you have a lens wearing a body rather than a body wearing a lens. I try to support a big rig by holding the lens all the time, wary of stressing the body's lensmount by holding just the body.
I have some 39mm Leica fit lenses , so thought my CV 35 f2.8 Color Scopar might be a good match too .
At 35mm you're reaching the focal length range where corner softness on m4/3 isn't much of an issue. The C/V 35/2.8 makes a pretty compact 70/2.8 equivalent, and the nearest native m4/3 lens is the pricey L/P 45/2.8 macro.
It would be fascinating to see directly through my Russian lenses too - 1930s Elmar perhaps !
Like a Visoflex on steroids, the ability to view through lenses formerly not possible is one of the very cool attributes of mirroless bodies. Likewise, the ability to grab HD video through legacy lenses is mighty cool, too.
