A few A's:
I feel like a bit of a heretiQ for comparing our beloved teleQonverter to normal TCs. It's important to me to know the advantages and limitations of the tools we have available, so it's a comparison I feel I need to explore. Going into this first test I had a hunch the TCs would win. Then on first looking through the sets of shots my initial conclusion was that the Q won hands down. Then on looking closer I got to where I am now -- the two could be very close indeed. I will do more testing, but if this conclusion holds up then it will come down to handling differences and convenience.
The initial samples are 25% crops, 2800x2100 pixels resized to 700x525.
Effective FL of the DA*300 on the TCs is 840mm (actual value, not taking "crop factor" into account). This rig on the K-5 has a wider angle of view than the 300 on the Q. However, the 2.8x boost from the TCs is very close to the Q's boost in pixel pitch compared to the K-5, which is about 3.1x. I'm more interested in this latter difference, because it gives a better idea of how large you can take the image in final output (print or screen).
I use an Arca/Swiss plate on my DA*300 tripod foot; it's a bit over 3" long. Fortunately it is just long enough that if I mount the foot backwards I have just enough room in the clamp to get the whole thing to balance. I've been meaning to get another rail, though, to complete my pano/gimbal rig, and then I won't have to reverse the foot.
Some people like to poke a tiny hole in one end of the egg. Pointy end, I think. I can't be bothered.
