isn't the battle over 2.8 and 4.0 a little ridiculous?

I constantly see people talking about 2.8 like it's a godsend. In real world shooting, if you can't get an image with f4, how likely is it that it will be a great shot at f2.8?

Maybe I'm just not in the correct conditions to recognize it. I feel that I'd need a fast prime to capture the images in dark situations that I can't with my other lenses.

this is not taking into account DOF issues, just being able to get the shutter speed to get the shot.

Shooting at band? If you're shooting at 1/50 @ 6400 ISO with f/4, you're more likely to get blurrier shots than with f/2.8 and a higher shutter speed.

That's just one example.


My village called. I was told that they missed me.

It all depends on what you need really. I mean if you shoot moving subjects in low light conditions it's better to have 2.8 or faster. Take the 70-200mm for example: wedding photographers need 2.8 because they shoot weddings. For others that only use the lens outdoors the 4.0 is perfectly fine for them.

Its not a giant leap but like you mentioned when your pushing the edge with that extra stop to get a shot its there. 2.8 is very nice but I consider 1.4-1.8 aperture lenses to be "fast". But sometimes you need the reach of a 70-200mm 2.8 because your 50mm and 85mm are just too short.

There you go...

Indoor concerts, indoor sports, anything indoors where you need to stop subject motion, the extra stop can be a make or break type of thing.

For instance, I was shooting a concert late last year, was at ISO 3200 (didn't want to go ISO6400 on my 1DMKIII), shutter speed of 1/160 to stop some action, and f2 on my 200L. That extra stop sure came in handy.

I shot some hockey earlier this year for someone. I had the 1DMKIII + 70-200 f2.8 IS. Was at ISO3200 (Again, didn't want to use 6400), 1/160, f2.8. With an f4 lens, I would have either had to shoot ISO6400, or at 1/80, which would be too slow.

Newer DSLRs can also auto focus better with lenses that are f/2.8 or faster.

I couldn't shoot hockey at all with an f4 lens. I could.. but I wouldn't be happy with the result, and as you said DOF also plays a roll in this.. especially with sports.

Having shot with both the f/2.8 and f/4 versions of a couple lenses; most notably the 70-200. There are times when I need the extra light to get the SS I need.

I would rather have it and not need it than need it and not have it.

and I don't think it's really a "battle". The lenses serve different functions for different shooters.

What battle?

Is there one between the f/4s and the f/5.6 zooms too?

Seriously,. different tools for different needs. I own f/4, f/2.8 f/2 etc...
No battles being waged in my bag at all.

However, when I shoot low light events, the lenses I use are f/2.8 minimum, with more time going towards the faster primes @ f/1.x or f/2

The difference is 2 times. That means that you shoot at ISO 800 instead of ISO 1600 or shutter speed 60 instead of 30. Feel the difference ?

I agree. Sometime one stop make or breaks a shot, often it doesn't.

You can take this argument and go from a 24L to a kit lens, too, if you take it far enough.

No battle here...a purpose for each lens. f/4 is fine with good light. 2.8 (and faster) is for shooting in low light. Got glass and both apertures, some with overlapping focal lengths; use 'em all frequently depending on the situation and what I'm going for with the shot.

These days with super ISO cameras not so big a deal, in the old days it was the difference between 400 iso positives vs 800 neg film....

not everyone shoots landscapes, portraits (with supplemental lighting) and outdoors in good light. f/2.8s are the slowest lenses I own.

You don't have a chance shooting basketball indoors with @ f/4 and 1/160 shutter speed. f/2.8 a big deal over f/4? You BET it is!
