Hi all,
I recently came across a Kenko TelePlus 2x MC7 P/AF Tele-converter.
I purchased it in hopes of finding an auto-focusing lens on the cheap that I could effectively go birding with a Pentax K-S2.
I've done some research after the fact, and I've read that people suggest to only use a 2X converter with lenses faster than f/2.8 or shorter than 50mm.
1) Is this true?
2) Could you please suggest some lenses that are relatively cheap and common that I could look for and use with my new converter? Auto-focus is much preferred. And hopefully longer than 300mm?
3) I might be able to get a Pentax SMC DA 55-300 f/4-5.8 for about $150 CAD.. Would that work well with my 2X converter?
4) Any links you could recommend that already discuss this sort of topic?
Thanks for your help everyone!
