Question: I realize that this is a 35mm prime lens but does anyone know how it compares with the 35mm with the Tokina 17-35mm zoom at 35mm?
Document: Sure, carrying this plus a longer lens or a zoom sort of defeats the purpose of traveling with, say, the 24-70, as it is two arguably smaller lenses versus one large, heavy one... But if you know your limitations and accept them, this sure makes great shots that also travels much easier. The 50mm lenses are smaller and travel better, but I believe the 35mm is a better compromise for travel and family shots, even on full-frame.
I have a variety of good Nikon glass, including my standby 2.8 24-70 FX zoom. This has become my go-to lens though. I have a 50mm which I felt was a little too long for some situations and a little too short on others, on my D800 FX sensor camera.
This package will deliver 90% of the results of what you will get with pro camera/bodies and lenses, but pro kit will cost you at least FOUR times as much. If you are not a pro or if your don't have disposable money then go for the f1.8 series of lenses.Why did I buy this lens?First reason other than I don't have a 35mm is, summer is around and I will have more chances to shoot outdoors, else I would have waited for a deal.
I consider this lens at least 200-300 USD more expensive than what I would like to spend on something of this value. In my opinion one should own 35mm and 85 mm if your camera is DX/Crop Sensor (like D3000/D5000/D7000 series) or 50 and 100/105 mm if your camera is FX/Full Frame (like D600/D800/D3/D4 series).
I love this lens matched up to my D610. I have it on all the time and it a great walking lens too. From portraits to car photos to event photography this is phenomenal. I had the Sigma 35mm 1.4 lens but after about 6 feet it had major focus shift issues so it was pretty much useless. This is great and tack sharp at all length and much much lighter too. I highly recommend this lens even over the mighty 24-70.
*** 3 Stars, because of its price ***Why buy a 35mm FX (Full Frame) lens?I own a D7100 (a DX body) along with 85mm and 50mm f1.8 FX primes, and these are too narrow on D7100 for group shots, effectively portrait solutions only. I wanted something little wider so that I can also shoot small group of people, indoors (like dinners, small gatherings etc..) and outdoors to keep things in context (read on).
I've owned every autofocus 35mm lens for Nikon. First the 35/2D, then the 35/1.8G (DX, on both DX and FX), then the 35/1.4G, most recently the 35/1.4 Sigma, and now I just received the brand new 35/1.8G FX. The Sigma is still the best of the bunch in terms of image quality and build quality, but this one is my new favorite because I value the smaller size and lighter weight.
Second reason is that I will upgrade to FX body fairly soon, so it didn't make sense for me to buy 35mm DX even though it costs only a third of the FX.To me lenses have only two uses while considering focal length and aperture... First is to KEEP BACKGROUND OUT OF CONTEXT and second is to KEEP BACKGROUND IN CONTEXT.
Its wide(FX)/normal(DX) standard2. Large aperture f1.8, good for lowlight and videos.3. Fairly well built (compared to zoom kits)4. Focuses fast enough5. Sharp photos6. ED elementCons1. Expensive for the value, they could have given nano coating for the money2. It will not survive an accidental fall (but thats common to all f1.8s from NIKON)3.
I had hoped it would render as beautifully as my 50/1.8G. It's clear from the early samples that it does not. I returned it.
Answer: A prime lens will always have optimized optics for the focal length it is (because there is only one).  A zoom will have to have compromises, even if minor, due to moving parts/optics/etc. I own a tokina zoom that is quite good, but second-tier lens makers can also have quality concerns compared to the major manufacturers. If you can actually resolve the optical issues (if any) is another issue.  It's easy to find fault of a lens with a picture blown up to 100%+ on a big computer screen.  Much tougher at practical sizes and print.  So don't sweat it.  That saiid, this is a marvelous lens with great optics and low-light capability in a reasonably compact size.  Highly recommended.
