Hey all,
I have been thinking of picking up a B-300. Has a good reputation.
I have a couple of questions though.
1. It seems that this 1.7x teleconverter will not increase a lens' f-stop.
How is this possible?
2. If I put it on top of my 135 2.8, I will get a 230 2.8 (if 1 about is
true). What will be the performance of such a setup when compared to the
200 f4. I thought this setup would be good for astrophotography.
Thanks!!!
-Bill
