Originally posted by Ron Boggs After having wandering caribou come too close for the FA*600/4 in Denali and a rutty Pronghorn slip right next to my truck/blind and too close for the FA*600 I sprung for the FA* 250-600/5.6 and loved it for more than 20 years. The insane close focus minimum distance and the ability to zoom out for animals walking too close to me made this lens a gem. What many don't understand until shooting through this lens is that it's also got extreme landscape extraction capabilities...crisp 16"x20" prints...
Somebody will be a big winner! Buy this lens!
Now you are reinforcing me to keep it no matter what
But since you've used both, can you talk about the effect of loss of one stop in those context ? To be frank, sometimes I'd like to have that margin, especially in the shadows, but I'd say 95% of the time, it wasn't really an issue with modern bodies that allows higher ISOs without much problem in IQ.
Here's an example of a shot I did at 12800 ISO the first time I got the K-1, pushing the body to the limits under low light with ISO 12800. Note that there was no sharpness or noise reduction (NR) applied on that one...
