All,

What Leica lenses would be suitable for use on the Olympus E-P3.

[i understand it's a broad based question]

M9envy

Camera in question is micro 4/3 with registry distance less than M system (distance between rear of lens and sensor/film plane), so it is suitable for both M & R lenses via adapter. Crop factor is 2x so for instance Leica's 50mm lens becomes 100mm lens on Olympus. In short all lenses are OK.

NO.

 

u43 sensor has no microlenses adjusted.

In practice - it does only make sense to attach lenses longer than 35m (inlcuding it), so you will only get tele.

 

Wider - soft edges, sometimes color shift. Of course you accept it or try to correct.

 

The same was with 1st generation of NEX'es.

2nd generation has microlenses adjusted like M9 - sharp edges, no color shift.

Which one is a first and which one a second generation NEX? Are you referring to new ones which are not available yet? And if so, how come you believe to know how they will perform with M lenses?

Wide M lenses adapted to m4/3 behave as explained above.

When you have this new E-P3 - congrats, it's a very capable little beast. My E-P2 together with the EVF and a 50mm Summicron delivers good results.

But when you are planning to use your M lenses regularly, the Ricoh GXR systems will be better:

The Ricoh is the only third party manufacturer who designed the module (APS-C) for the delicate short register of M lenses. Inside the cam you are able to adjust vignetting and color shifts (see M9) which in case of the M9 you have to do afterwards.

 

The disadvantage of the GXR compare to the Pen is the much slower AF with the original lensors (28mm and 50mm) but the cam is one of the userfriendliest cams on the market.

1st generation is NEX3 and NEX5.

2nd generation is already reviewed* with M lenses NEX3C and coming soon NEX5N and NEX7.

If you haven't invested in Ricoh yet - I would wait for more comparisons between Ricoh and NEX7, as NEX will have already built in EVF in left corner.

I've used the 35 cron asph and 50 lux asph with nice results. Not worth the investment in the lens unless you plan the m4/3 as a stepping stone to an M9 which is what I did. The rendition is slightly better with the Leica lenses but there's no wow factor. I still use the E-P2 with m4/3 lenses. Very nice pocket camera.

[mmradman]

NO.

 

 

 

I said OK, meaning you can attach and use it but I didn't make claim that results will be spectacular. If I thought result would be out of this world I would use stronger compliment.

 

Difficult to imagine anyone wants to use micro 4/3 camera with FF lens in extra wide role, only makes sense if extra reach is an objective.

 

There is only handful of full frame extreme-wide that you could consider to be wide enough on micro 4/3 to give you real wide; Voightlander 12mm and 15mm becoming 24mm and 30mm respectively (anything above 28mm on FF is barely wide). So when you attach extreme wide on crop sensor you only use lens sweet spot so optical anomalies are less of an issue than same extreme wides on the un-dedicated full size sensor.
