That is not to say that they won't try to AF depending on the light down to that number. After looking at Ron's work I can't ever see buying another 2x TC when it appears 2 1. I have the opposite experience, i tried cameras such as the SF series, the Nikon N and a few others, man were they ever slow and did they ever hunt in indoor lighting with the kit lenses F5. My DSLR's never had such problems.

However Ron, myself and others have shown many times the Pentax system dating back tot he K10D can focus at F8. I agree it appears two 1. We dig into the detail The Nikon Z mm F2.

Ron, thanks for setting up all the data and the warning regarding the DG-version. Question: I thought the only difference for the DG-version is its back lens coating to prevent re-reflections of the light reflected from the sensor surface?

I agree with Ron the one on the left is your best all round option if you cant afford the Pentax HD 2x converters are fun but not really suitable for serious images because ling lens where they are most useful tend to be slow and the 2 stop drop is just to much plus IQ drop with cheap one If its cheap and you want to play then nothing wrong with that 7 element converter you show there.

Ron Like i said, he sent it in for servicing and it came back fixed, the problem with the pin position was out of tolerance.

Ron If i had the lenses you speak of I'd try mine out on those lenses. Inconclusive for you but not for me. Take care Mike. F Forum M My threads. You may also like.
