We’ve detailed what we consider being the best and most suitable for each type of photography (portrait, landscape, etc.) and for every kind of focal length (telephoto, macro, etc.), and we’ve explained why.įinally, below each table, I’ll try to guide you and give you my point of view on the choice of lenses for each brand. If you wish to go further than this “simple listing” of optics for the Micro 4/3 mount, you can also read our article on the best m4/3 lenses. Thus, a 35mm on a micro 4/3 body will give a viewing angle of a 70mm on a full frame body, which I already consider as a “small” telephoto lens. Also, knowing that the m4/3 sensor is half the size of a Full Frame sensor (24x36mm – the universal reference), it is necessary to take into account this “conversion of focal length”. Even if a focal length of 100mm remains always a focal length of 100mm (it never changes), it is indeed the size of the sensor on which you will place your lens that will vary the field of view you will get in your viewfinder. You will find in the tables below the names “wide angle, ultra-wide angle, standard or telephoto lens”. By the way, I will also spend some time searching the web for the best adaptor rings, this could be a useful article to write for sure.Ī little reminder about the focal length. Without using special adapter rings, you will not be able to attach lenses of other brands (Canon, Nikon, Sony, etc.) to a Micro 4/3 mount body. To replace just the 12-60 and 50-200 with the 12-40 and 40-150 Pro lenses will cost you something like AUD$2,500, so that makes the E-M1 a no brain choice, IMHO! Specially if you factor in the cost of the excellent mFTs 1.4x TC.Īll of these lenses suffer badly in AF speed on all mFTs bodies without PDAF - i.e. My 50-200 MkI is perfectly adequate for my needs. Of course, one gains another 100 mm in effective FL with either 50-200.

My 50-200 is the MkI, and some with experience of both versions, plus the mFTs 40-150 Pro, seem to prefer the MkI to the MkII (SWD), and regard both as being the equal of the 40-150 Pro in everything but blindingly fast AF. I don't have the Sigma, but there are many reports here of very (excruciatingly) slow AF, and inaccuracy of many Sigma lenses on the E-M1. I don't have the 12-60, but others whose opinions I trust swear by it on the E-M1. The 40-150 MkI is much better than either of them for both AF speed and accuracy in all light (!), and optically. Both are slow to AF in really poor light, and not accurate. sigma 18-50 and two old OM manual lens 200 and 50.įrom my testing, the 14-42 and 40-150 MkII are not at their best on the E-M1, but are CDAF compatible.
