But there are considerable NONnegligible differences between, say, 1/2 @ 2.8 and 1/8 @ 1.4. These differences may not be significant if you normally shoot sunny 16, 1/100 @ f16, but if you're pushing well below normal visible light for your images, 2 stops of extra range is going to be a thing to kill or die for. I'd prefer a 24/1.4, but either one goes right to the top of my "I'm saving for a" list. > Digital Users: if you have an M8 ( or M9 or M10 or whatever it will > be called) all you have to do is to up the ASA .... it is a dial > issue. Unfortunately at the level where the differences are significant and worth the money, there's a very sizable quality issue as well. The M8 allegedly (I don't own one yet) runs out of top end around 640 for high-end uses. That starkly limits what you can do in the dark with a 2.8 len. > I am unimpressed from a marketing point of view. > Technologically, I think it is genius, but genius does not keep the > doors open. It helps, especially if you're setting examples and showing off capabilities in the rarefied world of truly high-standards camera imagery. -- R.
