I've had an email from Olympus recently to mark the third anniversary of my MyOlympus membership and offering me 15% discount on my next online order from them. I thought that was very generous, and I'm thinking of purchasing the MC-20 converter for use with my 40-150 f2.8 zoom.
I have the MC-14 converter and the image quality is excellent; I struggle to tell any difference in IQ when the converter's on or off! However, a 2x converter's a different matter. For those who've got this converter what is the quality like? I would end up with a 80-300mm f5.6 zoom, which is a bit slow, so I wouldn't really want to have to stop it down further just to get decent IQ. Also, how does it compare to the Panasonic 100-300 f4/5.6, which I could probably get secondhand at a similar price?
Looking forward to your comments.
