» Click to show Spoiler - click again to hide... « Maybe you can bump up your ISO by another 2-3 stops (ISO 800/1600 if lighting not bright enough or 'low light' / 'dimly lit'). Also, 1/10s shutter is a bit too slow if handheld I think. On manual exposure mode, you may want to learn using the 'exposure' meter on your cam.

true ...but in this case, you are already at the limit of a good source of lighting.
hence, you should open up more aperture (f/1.8, 2.8, 3.2, etc).... but that is not possible with your 18-105 f/3.5-5.6 lens. the other is slowing further your shutter to get more lights in, but again, not possible because your shutter already at 1/10s. Go even slower, and you'll get even more 'motion blur' or handshake. So you got only ISO to play with (increase it further)...... or add more lights to get faster shutter speed and maintain the same ISO. I believe d7k can still give good & usable image even until ISO6400. *added* On manual exposure mode, you may want to learn using the 'exposure' meter on your cam.

QUOTE(tongweng @ Dec 3 2012, 10:02 PM) low f number means bigger aperture.or the other way around, bigger f number means smaller aperture. confusing eh? ..hehe. example 1 : f/8 vs. f/5.6 f/5.6 is 'bigger' aperture and brings in more light. (but at the same time your DOF is shallower too) example 2 : f/2.8 vs. f/1.4 same as above. f/1.4 is bigger aperture than f/2.8. so how about #1 --> "f/8 vs f/1.4" #2 ---> "f/5.6 vs. f/2.8" which one gives more light for the two cases above? Can try and guess? This post has been edited by mmohdnor: Dec 3 2012, 10:10 PM |

Alright, D800 and D800E owners best to check your unit for AF issue! I verified my D800 + another D800 + another D800E just now... all affected with left AF.

Sounds like your right having issue instead if you AF fine tune to center ISO, shutter speed, aperture. master these things first then get into the other stuffs. do u have a fren who can teach u? looks like u do. learn with ur fren, shooting is fun, really fun! mine last time left and also middle |
