Re: Canon EF 70mm-200mm is ll USM Lens

I went to the 2.8 for extra light it would provide while shooting after sunset and illumination was provided by artificial sources. My camera is below yours with respect to ISO maximums, therefore the 70-200mm 2.8 allowed the lighting I required. I was unable to compensate with ISO, so the 2.8 was invaluable for me. If you are able to get the images you wish with ISO and don't want the weight of the 70-200mm 2.8 then I would continue as you have. When and if the time arises that you are no longer satisfied with your pictures and are unable to compensate, I would make the upgrade to the 70-200mm 2.8 at that time!

Also, the majority of the shots were at 70mm, then...
If I shoot at 200mm, is the light constricted even more; the higher the mm, the more you have to add/accommodate your lens with light?

Please help me make my decision before the season comes in a few weeks.

Thank you for your help 


No, all versions of the 70-200 are "constant aperture" zooms, which means that their widest aperture is f/2.8 (or f/4) at all focal lengths.

One thing, it is only one stop.  Not a world changer by any means.  If you commonly shoot at ISO 1600, it means you now can shoot at ISO 800.

A lot of Canon stuff. Along with, a lot of other stuff.

It can be a world changer of you plan to use an extender. I know you don't like extenders, Ernie, but not everyone shares that aversion. Especially on a good lens like the 70-200, which doesn't suffer an IQ hit when used with an extender of comparable quality.

You have more issues if one stop changes your world.
