Originally posted by Larrymc Precisely how many in focus similar shots do you need. I find the buffer on the Mk III to be perfectly adequate for any situation I have encountered, but I have not encountered every conceivable shooting situation. I do shoot aircraft and humming birds with a bit of success. Being able to anticipate the moment and trigger the shutter for a 30 shot burst will meet the needs of 98% of shooters. Supersonic frame rates and overly large buffers are mostly "bragging rights" territory in my opinion.
My observation as well, when I go to shooter's Facebook pages who were beside me that day to see what they got I always wonder "why do these continuous shooting 15 FPS shooters with the extra fast lenses etc. not get better images than me?" And I'm shooting 8 fps and sometimes lenses with slow motors. To me 12 fps is a nice improvement but not necessary. But if some day I get a Katie, I'll appreciate it. But is it a necessary upgrade? hardly.
A few images taken with my K-3 that were better than what was posted from other photographers.
The guys with the big lenses couldn't move around, the people with the point and shoots couldn't get enough reach. Shot with the K-3 and DA* 60-250
Same here, everyone else sat in the parking lot with their huge tripods and lenses. I scrambled up a huge snow bank made of snow piled while clearing the parking lot to get to the same height as this Pine Martin who's about 10 feet up a tree. Same deal, none of the big name $15,000 set up guys got anything close to this image. I'm shooting with $3,000 worth of gear compared to everyone else's $5k bodies and $15k lenses.
There were six or seven guys shooting this day, including some of the park's best known photographers, even with my tripod and 500mm set up, I'm more mobile and look for better angles. As long as your equipment meets a minimum set of relatively un-impressive basic criteria, skill always trumps gear.
The video establishes what camera has better features, but passes on the more meaningful question, what kind of photographer needs it? I'm not convinced I need any of them. At this point it's all about "what frills would I like next time I have to buy a camera." (Because every camera company includes frill I own't ever likely use.) In the few minutes I watched, I saw nothin that would convince me to switch brands, or buy a new camera before my K-3 goes down for the count.
