Hi all -
I've done some pretty extensive searches online about this and haven't come up with a verdict yet. My question is partly academic, as I just ordered the damn thing (and will share the results!), but I am wondering if any of you have used the 645 1.4x teleconverter with the longer telephotos... and of course, ask how they performed.
I just bought the 1.4x TC with the hope of using it mainly on my 200mm f/4 FA but also on my 120mm f/4 FA Macro when it's called for.
The TC is billed as "optimized" for the 300mm f/4 but also as compatible with both of my telephotos... any possible explanations as to why that might be?
Is there a lot of sharpness / contrast loss in using the TC?
Thanks for your thoughts and I'll contribute mine as soon as KEH ships my goodies out!
