Advice for my next wide angle?
Hello everyone, I find myself in the conundrum of which lens should be my college graduation gift. I've narrowed it down to these 3 and I will list my reasons below for wanting each one. I currently have a Nikon D7100, 18-105, 50mm f/1.8G, and 85mm f/1.8G. We also have the Nikon D3200 as the "family camera" and I sometimes use our 35mm f/1.8G, but whichever one of these lenses I get would be my own. If anyone out here owns one or multiple of these 3 lenses, I would love to hear your input on which one you like the most/prefer and why. My main goals here are to get a lens that would be suitable for all or multiple of the following things (in no particular order): Street photography, star field or star trail photography (and thus landscape/cityscape photography), and videography. (I am aware of how some of Nikon's older D lenses with aperture rings could be best suited for doing videos, but since I would mostly be wanting to make tech-related videos on YouTube, it wouldn't be as important to to me to have aperture rings etc)
I would love to have this lens because it would essentially complete my Nikon 1.8 prime lineup, and the fact that it's FX means I wouldn't have to give it up in the future should I go full-frame (which granted, could be as long as 5 years from now). I basically would choose this as an alternative of buying a second 35mm f/1.8 to have all to myself and would like to use it for star field and star trail photography, as well as street photography. Carrying the 28, 50, and 85mm f/1.8 primes in my camera bag would give me all the versatility I need for portraits and low-light photography, since the 35mm focal length is a bit closer to 50 than what I would prefer. It's a lens that I know I would be using for years to come since I don't plan on plopping big money down on any f/1.4 lenses any time soon. And it's a Nikon with all the bells and whistles, so there's that.
Ah, but now there is this one, which would effectively act as multiple primes, however, it's a bit more expensive and my budget is simply as close to $600 as possible (and it is hard to find this lens for that price on eBay since it is so new). The only other downsides are that it's a bit heavier and larger, however, I could see myself using these lens maybe 70+% of the time, and there's the fact that it's for crop sensors, so if I upgrade in the future, I would either have to keep my D7100 around, or get rid of this lens. But that aperture and versatile focal length range are even more appealing for landscape and astrophotography than the 28mm Nikon. I am slightly hesitant about buying third-party lenses, as it sometimes seems to be hit or miss whether sigma lenses wind up with focusing issues etc. However, this lens being the first of its kind seems to be immensely popular and from everything I have read, Sigma's Art lineup is pretty solid. If this lens was $600, I think it would be an absolute insta-buy for me.
And lastly, there is this one, which I feel as though I absolutely HAVE to have an ultra-wide angle because not having that spectrum covered is driving me nuts. But there's also the chance that I could convince my dad to get this one for our D3200 (since my brother also kinda wants it), and simply "borrow" it for when I want to use it. I've seen a few reviews where this lens gave some people focusing issues, but DxOMark seems to rank it is the best wide angle you can get for APS-C sensors, better than both the Nikon and Tamron 10-24's, as well as the Tokina's. and I love the fact that it has a constant aperture since I would largely be wanting to use this for landscapes (also more astrophotography) and for making YouTube videos where having an ultrawide in my room is pretty much essential. And when it comes to ultra-wides on crop sensors, you really have no choice but to go with a crop lens, which is perfectly fine with me since 10mm (15mm equiv) is basically the widest you can get and it would be YEARS before I ever got a Nikon 14-24 f/2.8.
So what are your thoughts? Which lens do you guys thing would give me the most value and image quality and be the best investment? I am leaning towards the 10-20 and 28, but if I can snag the 18-35 for a sub-$700 price, then they all are on pretty equal playing ground. (and I think that both the 18mm and 28mm focal lengths would still be plenty wide enough for setting up videos in my room, but I would also love to play with the creativity ultra-wides offer with their exaggerated perspective)
