Re: New MC 20 announced.

Yes, the 2x Canikon converters are a bit rubbish, but modern design and glassware has apparently solved many of the issues, at a price, and the recent Sony and Panny versions have been pretty well reviewed. Some image degradation is measurable apparently, but how much if that is visible in real-life images is another matter.

For example: https://www.dvirbarkay.com/single-po...nverter-Review

After all, you can measure a fall off in max resolution when the Oly 1.4 is added to the 300, but anyone who claims to see significant degradation in as-used images needs to get out more!

Iím confident Oly will deliver something good, and I agree it might be particularly useful for me on the 40-150.
