I currently own a Nikon D90 (DX) and a Nikon F100 (FX). The D90 came with an AF-S DX NIKKOR 18-105mm f/3.5-5.6G ED VR. I also have an AF-S VR Zoom-Nikkor 70-300mm f/4.5-5.6G IF-ED. I just bought the F100 and I need a lens for it. I have noticed my growing need for a fast lens in low light situations, and have also grown fond of bokeh.
I need a lens that will work in low light, and that will work for both my Nikon D90 and F100 (meaning it needs to be an FX lens). I have researched a lot and have found these two lenses one is a DX lens and the other one an FX lens. I don't know if it would be wise to buy two lenses that are so similar, one will work only for the D90, and will work as a 50mm due to the crop sensor (http://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/2183/AF-S-DX-NIKKOR-35mm-f%252F1.8G.html) and the other one will work for both (http://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/2199/AF-S-NIKKOR-50mm-f%252F1.8G.html). The problem is that if I buy the FX 50mm (second link) I fear it will be too long when used indoor. I want it mostly for shooting street photography, but I know I'm going to use it for indoor photography eventually.My concern is I might not be able to fit the entire scene indoors.
I have researched this lens (http://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/1923/AF-NIKKOR-35mm-f%252F2D.html#tab-ProductDetail-ProductTabs-RatingsReviews) which seems to be ideal and it isn't that good. This one is ideal but is very expensive (http://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/1923/AF-NIKKOR-35mm-f%252F2D.html#tab-ProductDetail-ProductTabs-RatingsReviews). This is another choice but it is a manual focus and to be honest if I'm going to spend $1000 on a lens it better have auto and manual focus. Another lens that I researched (http://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/1435/NIKKOR-50mm-f%252F1.2.html#tab-ProductDetail-ProductTabs-RatingsReviews) is this one, but it cost $700 and is manual focus. I'm open to any other brands that aren't Nikkor as long as the lens is sharp and has nice bokeh.
Any suggestions?
