Hmmm.interesting to see this here...I have a very nice FF kit (check specs down below), and I also maintain a full MFT KIt......I decided to order the Oly 40-150mm Kit from Osaka , with included TC1.4x. (lens not available in US and Kit will not be sold here..I saved $100!....)I just saw the possibility of really expanding that kit to a place that I had not imagined. Took delivery this week (free postage from Osaka took 2 days to get to NJ?
)...came with free gift and one dime. That's right...one dime in box!
The lens is impressive on my EM1 and the matched TC is like having more reach with no penalty other that f/4. My preliminary tests are making me very happy that I made this choice. No...it's not a FF sensor..but for most of my needs its all there in a small way.
The new Oly Lens is large for MFT..but not in comparison to other systems.
If you take a look at this: http://camerasize.com/compact/#482.444,579.392,312.7,ha,t
We can see that the Sony set up is only f/4 and has way less reach. The Canon setup has way less reach and teh TC1.4x III is sooooo much larger than the little sliver of the Olympus.
Yes..yes..yes.... ..this is not FF...but I have to say..if you know what you are doing shooting and with post production..its damn good. And its in a significantly smaller and lighter package. Not for everyone..but I can see I will be grabbing my MFT kit more often because this lens is in it.
