K-3 Stacked 1.4 and 1.7 TCs
ƒ8, 800 ISO, AV
Can I use stacked TCs on my DA*200 ƒ2.8?
While I realize the true test of a lens is distance, not close ups, the short answer is yes, it does, it's awesome. So, in good light, I present 476mm and ƒ8 with the 1.4 TC next to the body and the F 1.7 AF converter in the middle.
We have our first sparrows today.
It would appear the problems I've had stacking in the past were caused by not having an ƒ2.8 lens to start with. The other thing that comes to mind is, this package, going to 476mm and ƒ6.3 wide open, is a fraction the size of a Bigma. Not only that, starting at ƒ4 with my 60-250, this combo doesn't work well. My maximum reach with the 60-250 and 1.7 is 425. The maximum reach with the 300 is 510. Essentially it looks like I'm going to get all the performance of those two lenses well as the Bigma and various 500mm zooms. Compared to anything else, of equal range, this is a joy to carry, and these images are all taken hand held.
Now how much do I want that A*300 2.8 ?
