Rethinking my gear.
I am evaluating my lens collection again and toying with the idea of moving on the 100 - 400L 4 - 5.6 for around £925.00 and going for the 70 - 200mm F2.8 with a TC. However, how many stops would I loose with the 2x convertor I think it would end up at F4 when extended - am I correct. This is still better that the 100 - 400L @ 5.6 when light is required.
Any ideas on TC's reductions on stops?
