Originally posted by Tammmzy Hi there everyone,
I'm wondering if I could get some expert advice on my next lens purchase. I currently have a 50mm 2.8 macro lens, and an 18-250 tamron as well as a 10-17pentax fish eye.
I am wanting a lens that is best to use indoors in more low light settings. I've been told to get the 50mm1.4 but i'm wondering if thats redundant since I have a 50mm macro lens. Obvoiusly the 1.4 would be better but i'm wondering what ppls opinions are on it. I also have seen a 50mm 1.2 and am wondering if theres a big difference between these lenses.
Any advice would be GREATLY appreciated! I'm still learning and have lots to learn!
Thank you!
Welcome to the forum!
The f/1.4 to f/2.8 aperture range makes a world of difference to the images and the type of shots you can get.
It's harder to get focus at f/1.4 because the depth of field (DOF) is so small, but it's possible - the only problem being that someones eye will be in focus, but their nose will not.
(not necessarily a bad effect - do some googling on bokeh and DOF and you'll see some images that show you what I'm taking about.)
If you stop any 50 1.4 down one stop to f/2, it will be very sharp, DOF will be usable, and you will have double the shutter speeds available than you do at f/2.8 - meaning, if you need to shoot at 1/40sec at f/2.8, you'll be able to double that to 1/80sec (or I should say, the camera will do that for you if it's a A or AF lens.) 1/80s vs. 1/40s often means a sharp shot vs. a blurry shot.
I'd buy the FA 50 1.4 for $160 - $200 or so. At f/2, that thing is an incredible performer. The F or FA 1.7 ($120 - $180) is excellent also, even wide-open at f/1.7.
Don't bother with a 50 1.2 lens at this point - the f/1.2 aperture isn't going to be as useful to you because of almost non-existent DOF. Plus, they cost an arm & a leg.
I'm sure others will have advice for you also.
