p.2 #1 · Am I asking too much of a 50d plus 70-200 f/2.8 | |
I am aware that there are limitations to the capabilities of equipment. Using your example, if I had consistently seen noise in other's experience with a 1d series camera at a given ISO, I'd call it an equipment limitation.
But I have seen many many many examples of this lens producing high quality (i.e. sharp) images at f/2.8. I don't consider this one fixable in PP. Maybe it is the body, but the lens is typically regarded among the best (many saying it is better than the IS version).
In this case, I don't HAVE to shoot at f/2.8, although I get a couple of benefits:
- I had the sun going in and out during the game. At f/2.8, I never have to worry about shutter speed, although in full cloud it would drop to 1/500 or so at ISO 200. Notice that I didn't blame the camera for soft images at 1/500, because I'd consider that at the low limit of ability to freeze a moving player and / or ball - even at U10.
- I have really terrible backgrounds. I can't shoot this game in any direction without another game, parents, coaches, parking lots or porta potties behind the player. F/2.8 helps blur the junk behind them.
And as I said, in this game, I did have choices. Many times I won't. I really will be shooting dress rehearsals of the Nutcracker in a few weeks, and if I'm not at f/2.8 with ISO maxed out (and I'll have noise and need neat image or Noise Ninja to clean them up) I won't get anything but blurs dancing.
And to give a non-photographic reference, would you expect a barber to perform worse on the first (the F/2.8 version) or last (f/22 version) of your haircut. Imagine the response to "sorry, but you were pushing the limit of my performance by coming in first or last - I know you paid the same amount, but I just can't be expected to perform as well when you push to the outer edges of my opening and closing times".

So what happens in circumstances where I need f/2.8 to achieve SS?
I've heard this suggestion before, and while it would likely improve the sharpness, I'm one who thinks that if a lens is F/2.8 and has the L label, it should actually work at f/2.8.

If it was me, I'd shoot at F4 or F5.6 for increased DOF. In this light you still have plenty of headroom for a fast shutter speed.
At the risk of sounding overly snarky... are you not aware that photography is all about making choices for your exposure... all of those choices require have advantages and disadvantages and you have to make concessions for what you are trying to accomplish in your image and your exposure.
Let's look at the argument another way and see if it makes sense... Imagine someone posted the exact same picture, but told you they had shot it at ISO 1600, 1/3200, f/8 and they were complaining that they thought the the noise in the shot was excessive... Your first reaction would be, "well, why'd you shoot it at ISO 1600?" and if that person then said, "well I have a 1 series and there is still some noise present. I think that a 1 series professional camera should be able to shoot at 1600 just as good as it does at 100".. you'd say, this guy is crazy, he obviously doesn't understand that there are drawbacks and consequences that will result from that decision. We all understand this when it comes to ISO... i'm sure you do too... when you push equipment to its absolute limit... even the best professional equipment you are going to have some drawbacks... in the case of aperture, you are going to lose some sharpness. As others have said... you have plenty of room in terms of shutter speed, so you could shoot that at ISO 400, 1/800 and f/5.6 have still stop all of that motion with a sharper image... why does it HAVE to be shot at f/2.8?
