Quick background: I shot Nikon in the days film (still own an F4) but switched to Canon when the first Rebel came out (because of lower cost). Been solidly Canon since then, but also always sort of wondering if I was missing anything on the Nikon side, especially in the past couple years. It just seems like on the camera side, Canon has been lagging Nikon by years in sensor technology.
I currently have a 6D with 24-105L, 28 f2/8 IS, 35 f/2 IS, Tamron 45 1.8, 70-200 f/4L IS. I think the 6D is a great camera overall, especially since I don't shoot anything that requires ninja-level AF. This set of lenses is also a great fit for what I shoot, although of course I want more/better glass (don't we all).
I saw an opportunity earlier this week for what *I* think is a good deal ($700) on Nikon D610 and snagged it. I also got a couple cheaper/older D-series lenses (50 1.8 and 35-105 3.5) which also will work on my F4 (just in case I lose my mind and want to shoot film again, haha).
So far, the D610 has really wowed me with the IQ (even with the older lenses)and overall feature set. It appears to be better at high ISO noise than the 6D, which is pretty damn impressive. I haven't really tested the limits of the dynamic range yet, but I have no reason to doubt the reviews and specs that say it will outperform the 6D in this regard.
But I'm noticing that it seems like there aren't as many modern lens options for Nikon mount. Or maybe it just feels like there aren't as many options. Seems like most of Nikon's zooms that aren't super-high-end suffer from exaggerated distortion, and that 3rd party lenses are better in that range.
So here's what I'm thinking as a lens compliment if I were to decide to flip over to Nikon:
• Tamron 24-70 2.8 G2 or maybe a cheaper option: Sigma 24-105 f/4 OS (I've been getting on fine with f/4 with the 6D)
• Nikkor 35mm f/1.8 G (FX)
• Tamron 70-200 2.8 G2
• Nikkor 85mm f1/8 G (optional for now)
Any input is appreciated. Also, am I crazy to give up lenses I like for a body I think is superior? I generally believe that glass is more important, but the Nikon features and IQ are very compelling. It's also possible I can keep my 6D and a lens or two (the 35 f/2 IS is an AMAZING lens) and still straddle the fence with Nikon gear.
What do you guys/gals think? I feel very conflicted right now, haha.
