Contemplating camera/format change. Opinions wanted
I've been shooting with my Olympus gear well over 10 years. It doesn't appear Oly is going to bring an updated body to market and I'm not interested in the smaller micro-FourThirds offerings. I've begun researching options and could use input. The Oly FT bodies are a 2X "crop" sensor so one thing it provided was some pretty good reach with smaller lenses. My current lens lineup with my Olympus is as follows:
ZD 90-250 f/2.8 zoom (this is my workhorse nature and wildlife lens)
ZD 150 f/2 prime
ZD 50 - 200 f/2.8-3.5 zoom
ZD 14 - 54 f/2.8-3.5 zoom (my widest lens at 28 mm effective focal length)
ZD 70 - 300 f/4-5.6 zoom (very light but IQ not great)
ZD 40 - 150 f/4-5.6 zoom
EC-14 (1.4 extender)
EC-20 (2.0 extender)
EX-25 (25mm extension tube)
Obviously my passion is wildlife photography but I also want the ability to take some decent landscapes from time to time. I also use my gear for photographing my family (school functions, graduations, vacations, etc).
I've been looking mostly at going with a Canon setup now. I'm thinking most likely a 5DIII (the 1DX sure looks good but might be a bit too much initial investment). I also briefly considered a Sony A99 but not sure if that's a good move considering what I've been through with Olympus. Anyone care to share some insight as to why they chose their particular body as well as what lenses I should strongly consider to start with? If I go full frame I'll definitely need a pretty long/fast prime I think. Also any good shopping tips for getting some new gear at good prices would be much appreciated.
