It looks like I'm going to have to replace my Nikon 80-400. It's a fine lens, but it's costing me images because it focuses so slowly. With birds in flight or airshows, or even race cars on a road course, it just isn't fast enough autofocusing.....
SO, WHAT do I replace it with?
My requirements are that the replacement provide VERY high quality images, be extremely fast, precise, reliable autofocus and image stabilization, be HAND-HOLDABLE for extended periods, get out to at least 400mm, and it would be nice if it was at least MODERATELY cost effective...
The Nikon 200-400 is nice, but way too heavy and WAY too expensive.
The Sigma 120-300 f2.8 OS may be nice, but again it's way heavy.
The Sigma 150-500 OS is a possibility.
The Sigma 50-500 OS is a possibility.
The option that's most often been recommended by people that are knowledgeable about lens quality is the Nikon 70-200 VR II with a matching Nikon 2X converter. Great lens for 70-200, and very good lens for 140-400.
I like the IDEA of the Sigma 50-500 but I've been reading for several days and there are a LOT (lot being a relative number compared to Canon or Nikon) of reports about autofocus problems and OS problems with the Sigma lenses... Even isolating things to just the last year, there are a lot of reports of problems....
And, unfortunately, I can't try one because neither of the big camera stores in the Minneapolis area will have anything to do with Sigma because of past problems.
So, anybody have any ideas or alternatives I haven't thought of?
