So I've been interested in shooting the moon. So there is the context, static object, tripod, don't mind manually focusing, etc.Well, fortunately the moon will last for a long time. Maybe long enough to receive your Tamron 150-600. I ordered one on May 24 from B&H and it's still back ordered. Ridiculous. I'm actually considering cancelling the order.
Unfortunately I've put my energy and efforts into what I use on a regular basis, and that is focal lengths under 100mm. Now that I am very happy with my kit in that regards, I'm looking to invest some funds on the tele end a bit. I currently own the 70-200 f/4.0L but know I want to upgrade to an f/2.8 model.
So I was wondering how well it would work to just stack a 1.4x and 2x teleconverter? It looks like I could get the Kenko Pro 300s for a little north of 300 bucks for both. So that would give me 560mm @ f/8.0. Would I be satisfied with the results? Or am I just wasting time at this point and should consider spending the $1k on the new Tamron 150-600?
Keep in mind, the 70-200 upgrade will occur. And that I don't really have a need for anything greater then 200mm as I'm not into wildlife, etc. Oh, and I shoot on a crop sensor (70D) if that makes a difference.
Thanks in advance!
