Olympus OM-D EM-5 Discussion

Well, after my brother came up with some OM compatible attic finds, I bought two adapters on eBay, and two legacy lenses, I now have the following range: Tokina 80-200mm OM compatible, two 50mm lenses (to one of which an old Olympus OM SLR is attached) Tongue, Soligor 135mm OM compatible, and an Ozeck Super "Close Focusing" 135mm lens (which the seller and I thought to be a macro, but doesn't look like it focuses that close at all).

I find some of the 135`s useful, especially if there reasonably fast, I have a Tamron adaptal 2 135mm f2.5 that I find useful.

Well, both the Soligor and the Ozeck are 2.8, which is one of the main reasons I was interested in them. Quite a good find for only a few quid, really. And the 1.8 50mm and the other fast 50mm should be good.

135 were generally quite compact and they will give you a useful reach on M4/3.

I've managed to get hold of a "New", unused copy of the canon fd 200mm f2.8 (in its original, seemingly unopened box with the documents inside also apparently unopened (a bit of lost old stock I guess) - thanks to Ffordes for that one

Its all in pristine condition with no sign of dust, fungus or other nasties so now I have the fun of finding out how to get the best from it Smile

So far I'm only playing with it on the EM-5 (hope to get The One back on Tuesday) and I have discovered how to set the magnified view (7x) so that with a quick press of the fn 2 button I have the enlarged view, stable in the EVF, to get the fine focusing needed.

When its in focus its as sharp as a tack and there is minimal CA but even the slightest missed focus provokes strong CA and fuzzy images

Hopefully I should have an hour or so on the Quay tomorrow to give it a work-out with BIF and the like but its looking a good buy so far Smile

Congratulations, that's a brilliant lens! Hope it works well for you on the EM-5.

So are you saying the CA is pretty bad in the out of focus areas Brian Smile

Most of these older legacy`s show some CA especially at there widest apertures.

if there are hard contra-jour edges yes Paul, unless I have the subject focused precisely, then the background usually appears OK, but it really is a critically small DOF.

some examples, haven't found any really awful purple CA but it gives an idea

Very impressed with the high ISO/low light performance of the E-M5. This was taken on safari at night, using the spotter's torch for lighting.

ISO 3200 - 1/25 - 100mm hand held. This is from the raw file in Aperture, with no extra noise reduction added.

Thinking of trying an OM fit lens - 400mm f5.6 telephoto lens, manual focus would one of the cheap adapters be OK?
Has anybody used this type of lens?

Hi Weddingblues, I've used a 300mm f/5.6 lens, some examples can be found here:

As others have mentioned, purple fringing may be noticeable when shooting wide open, but stopped down a bit should improve sharpness as well as image quality.
