I like the pictures! Perhaps you could in the future identify situations that do not call for such a short exposure time of 1/500 s, like the two right before the snap (at least with the K-3 III you could easily double that to 1/250 and in turn halve the ISO). But don't forget to return the shutter speed to the faster one when you have taken those shots
Originally posted by bobbyscon I'm off to figure out which of my kids organs to sell to get a 70-200 f/2.8.
The Pentax DFA* 70-200/2.8 will undoubtedly deliver the best quality, fast and silent focussing and WR, but consider buying used and perhaps have a look at used versions of Sigma and Tamron 70-200/2.8s (I own a copy of the Tamron 70-200/2.8 which I got used for a great price, but it's a bit soft wide open, though tack sharp at f/4.)
Another possibility to get a little more out of existing pictures would be a software for reducing noise. I personally use DxO PhotoLab with its so called "DeepPrime" denoising algorithm, but I've heard good things about Topaz DeNoise as well. (don't know what software you are using to edit your pictures)
