Frank I think the downsizing took away a bit of the crispness. The full sized images look pretty sharp at 100% although a higher shutter speed would have been even sharper. The little Sniper shot was at 1/500 from about 75 yards. The other 2 were at 1/400 which is about 1/2 of what I normally use as the minimum speed on the jets.
First photo is from about 40 feet, ISO 200, 1/400, 100 mm, f5.0
Second one is from about 50 yards, ISO 400, 1/400, 285 mm, f13.0
Last one from maybe 75-80 yards ISO 200, 1/500, 285 mm, f10.0
Camera is in Tv mode and I quickly learned that it's set so that the control dials are turning in the opposite way my other bodies are set for. Whenever I tried adding EC I was removing it so I've got to either reverse my other bodies to what's considered the norm or reverse this one to my way of shooting.
For now I'm concentrating on reading the manual because there are a lot of differences between the 1D4 & my 1D2n & 1Ds2 and there's going to be a learning curve but I think that after about 2 months of research I've bought the right body (vs 5D3 or Nikon D800) for my specific use. I came close to buying a D800 but there just aren't any lenses with a Nikon mount that meet my needs.
Rick it does seem to be an excellent match but until I try the 35-350 L (more reach is good for R/C as long as you can go a bit wide too when working the flight line). I'll know soon because the next weekend after the EDF event is an IMAC event with really big aerobatic planes. Unfortunately the patterns are done way up & way off from the flight line so the majority of photo ops are just the take offs & landings.
