You still get a 1 stop improvement in light. Also, just because it's a tele, doesn't mean that longer is better.
EG 100/2 Macro-Planar. On APS-C, at 150mm it becomes quite a different lens IMO use-wise. Making it actually 100mm-equiv FOV, and giving me f/1.4-level shutter speeds, makes it more interesting for using indoors w/ people.
Also, if you take the lens and both regular adapters and SB adapters in your bag, you've got two lenses for the weight of one, for the most part. 180/4 and 127/2.8. . .just switch adapters.
I should have been more precise. The link shows some vignetting with a 280 mm lens and severe vignetting with a 560 mm lens.
Above a certain focal length, around 200 mm, it is generally easier to get a lens that is shorter and one stop faster. That is what I had in mind.
The two lenses for the weight of one is a good point. I'll buy that
Anyway, mine shipped today. Estimated arrival in one week.
