400 2.8 without a doubt. Pricier but used ones can be had for £2500ish.
Tug, longer telephoto lenses let in less light so you would probably have been down to 1/100th sec @ 6400 using a 400mm instead of a 300mm.Hello Graham,
I picked up the 300 is version...Tried it out under very low light last night but I was using the 5d2 ...1DS3 Sold, so now just waiting for the mk4 to arrive.
The levels last night were only giving me 1/125@2.8@6400..... The results were very average for the settings. The light levels varied considerably around the pitch 1.5 - 2 stops. I can't wait to get out a do some Rugby at the weekend.It will be my luck that the weather will be atrocious ! ! !
I wish I had have bought that 400mk2 you were selling now...never mind another will come along, especially with the new canon primes coming out.

Isn't it common sense that a wider angle lens would be able to let in more light?
Maybe to you it is but not to me.
If you take a meter reading of a footballer running around in a field and the meter reads 1/640 at f2.8 and ISO1000 for example.
You now go to take a picture of the footballer. You have two lenses - a 24mm f2.8 and a 300 f2.8 - do you have to take a different reading for each?
Not being smart here but photography is capturing light reflecting off of a surface. In this case it's the sun reflecting off of our favourite football player in a field. No matter what lens, camera, filter, tripod, stool, peli case or wetgear you have, the correct exposure for the footballer is 1/640 at f2.8 and ISO1000.
Trust me on this![]()
Not strictly true.
Anyway, heres a quick test i did to prove im right.
Camera is a D3S set to f/4 using aperture priority mode for all 4 photos, iso set 12,800 for all 3 photos, i stood in exactly the same place to record all 3 photos within about 20 seconds, EXIF is intact in all 3 photos and going from 28mm - 75mm - 300mm is on the extreme side but its just to prove a point
28mm gave a shutter speed of 160th sec

75mm gave a shutter speed of 1/100th sec

300mm gave a shutter speed of 1/50th

haha I could be wrong actually. Although I just done a quick test with a 24-70 2.8 and I got an extra 1/3 stop at 24mm compared to 70mm. Not much I know.
Again not strictly true, the shutter speeds are saying there's almost 2 stops difference between the 28mm and the 300mm but neither are what you would consider under or over exposed by 2 stopsI think an easier way to put it would be to say that the narrower field of view that the 400mm has over the shorter lens would give a more accurate exposure of the target than that of the shorter/wider lens....This would also account for why the shorter/wider lens is more prone to giving a incorrect exposure of a target that is further away. It has a wider view that takes in all the other influencing light sources both incident and reflected.
When it started out it was simple....lol
But that test you did is the same as taking a picture of a horse, then one of an elephant and then another of a dog. They are completely different????Anyway, heres a quick test i did to prove im right.
I think the only way to prove this is to take a photograph of a plain white wall at all focal lengths, that way the meter can't pick up on the parts of the scene as it changes due to focal length. If this still happens when taking photographs of a plain wall at all FL's, then I will believe.

Also, the first one is underexposed a fair bit, the second a little bit and the third is about right. If you had used f4 and 1/50 for all three then they would all be exposed correctly for the chair. You would have blown out the sky in the first obviously but you were exposing for the chair were you not? It's the only thing in the three pics so I presume you were.
Take the footballer example again. When you are at a game what are you trying to expose correctly? The footballer.
OK, so what is lighting the footballer? The floodlights.
So, like your example above, he decides to stand in the one spot for a few minutes and you decide you would like a few different shots of him at different focal lengths. So you find out what are the exposure settings required to expose the footballer correctly. You use your 300mm lens to spot meter off his chest as he is wearing a middle grey shirtThe meter results are 1/640 at f2.8 and ISO1000.
You look through the viewfinder and notice that your camera is indicating that it will underexpose by 1/3 of a stop at the settings you are using but you take a shot of him in manual mode at 300mm and BINGO, you have a head shot and it's exposed bang on. The camera indicated it would underexpose because of the darkness beind him.
OK. So you now decide that you'd like a full length shot as well so you switch to your 135 lens. You put in the same settings and you look through the viewfinder and notice that this time your camera is indicating that it will underexpose by 2/3 of a stop at the settings you are using but you take a shot of him in manual mode at 135mm and BINGO, you have a full length shot and the footballer is exposed bang on. The camera indicated it would underexpose because there was more darkness behind him in the stands.
So finally you now decide that you'd like a wide angle shot as well so you switch to your 24mm lens. You put in the same settings and you look through the viewfinder and notice that this time your camera is indicating that it will underexpose by 1 & 2/3 of a stop at the settings you are using but you take a shot of him in manual mode at 24mm and BINGO, you have a wide angle shot and the footballer is exposed bang on. The camera indicated it would underexpose because there was more darkness behind him in the stands and the dark sky. The crowd isn't exposed correctly because you didn't want them exposed correctly but the footballer so the same settings were correct.
Now if you were to use Av or Tv or whatever Nikon use like your example of the giraffe, dog amd antelope above then you would of course get completely different values if you used evaluative metering but if you were to use spot metering on the footballer then you WILL get the exact same exposure values and if your camera doesn't give you the same values then there is something wrong with it. Must be because its a Nikon![]()

I am trying to figure out why you would attack Gary like.
I've not been on the forum long, but in that time it has become apparant that Gary (like many working pros on here - too many to mention) are extremely helpful & friendly.
They give their time and benefit of their experience free of charge and with the intention of helping people like me & others who wish to improve our photography.
I would suggest an apology is in order.
Please doI give up.
Thats the crux isnt it, we all shoot under differning lighting conditions so we all use the best method for our own conditions.the main point is to set the camera to give consistently the correct exposure for the conditions.
