Hi guys, I own a EOS 20D, a really nice camera but i don't think my lenses are any good....
I have :
EF 70-300mm 1:4-5,6 ( I know really bad aperture...)
EF-S 18-55mm 1:3,5-5,6 ( also bad aperture)
EF 28-105mm 1:4-5,6 (you know where i am going...)
I have a really hard time shooting anything in low light situations, even with ISO 1600 F4 and 1/500 i still got really underexposed shots from my GF's Gymnastics meet... hell even with 1/320 it was too dark...
The EF-S is too slow for something as fast as Gymnastics.. so I didn't even test it...
So in order to not spend too much money, I am now looking at non-zoom lensen like the 50mm 1:1,8 , very good aperture but don't you think 50mm will be "too much" , since I have a 1,6x Crop....
I just need a lens that performs well at things like Concerts, Parties, Gym. meetings(Gyms with bad lighting).
I hope i am right that with a lower aperture value, I can turn up shutter speed and still get a better exposed shot than with a lower F-stop(aperture value)???
If thats true how do I calculate that?
lets say I use the lens at ISO800 F4 1/500 and I get a nice picture, what would I have to change to get the same exposure at F2 ? I am guessing to lower the ISO or up the shutter speed? ( because thats what I am hoping)
I am fairly new to this, I know how to take pictures but the whole F-stop shutter speed thingy is something I learned 1 week ago.. so please correct me on any mistakes
If you'd like i could upload some pictures of that Gym meeting in order for you to maybe analyze what i did wrong ... (or the camera did wrong hehe)
