Or of course Olympus's own 60mm f2.8 macro. I'd be very interested to see how it fares against these two. It is the same focal length and aperture as the sigma and brings macro and weather sealing...

I don't know about the autofocus itself - that is of course the same for FF as for crop lenses.  The issue is with vignetting, but yes, you can use APS-C lenses with metabones for m43.  You...

I'm not familiar with the EM-5.  What is it?  I am very familiar with the E-M5 however. Michael

Mmm - of course you could use the speedbooster on this exact lens if there is one with the right fit.  The lens covers APS-C so will still cover all of the frame on m43 once speedboosted.  It would...

Mu-43.com or good old ebay! I've had success with both. Michael

Wisley in the snow, E-M5 with 20mm Michael

I don't follow - according to the EXIF that pic was taken with the E-M5 which has the same sensor as your E-PL5?  Unless I've missed what you're meaning? Michael

I have the 45mm 1.8 as well, indeed it was the first lens I bought for m43 along with the 14.  It is beautiful certainly.  However funnily enough it hasn't been on the camera at all since I got the...

No they couldn't - which is exactly the point.  For the previous example, comparable framing to a PL25 shot at 5 feet, the distance to subject and DOFs are the following: P20: Distance 4 feet, DOF...

The PL25 is a very different lens to the Sigma 30.  At all comparable apertures it is a bit sharper, on the cusp of being noticable.  The results, according to the oft-repeated LensRentals tests,...

Very interesting testing, thanks ogremage.  Indeed based upon this evidence one could conceivably think of the Samyang as for example a 9mm rectilinear with extreme barrel distortion issues...

The sharpness doesn't just compensate in part - there's another thread on here where one of the members compared the Samyang defished, cropped to an equivalent 9mm field of view and upscaled,...

The flowers are alliums, otherwise known as ornamental onions. The seed heads dry out quite well for autumn interest too. Michael

Ah yes, unseated by the new dpreview editor again. Apologies! Michael

Again, the Samyang / Rokinon is a great little lens.  Arguably optically better than the 12mm as well as being much, much wider if that is what you are after.  If the effect is a bit too dramatic...

Lovely lens.  Here's one of mine:

I don't think you're doing anything wrong - the 7.5 is clearly sharper than the 9-18 as evidenced by your first two shots.  Your Samyang looks plenty sharp to me.  Regarding defishing, the edges...

Sorry Andy, that link doesn't seem to work? I get a "Page not found" error. Michael p.s. Ah, I see the hyperlink you have is to http://www.dpreview.com/forums/previews/olympus-pen-ep5/ whereas it...

Hmmm - this is probably mine. or at least that's my thinking today! Michael

And, if you can wait a little while, Panasonic's own 42.5 f/1.2 will be with us - see here. Michael
