I currently own a d5200, I love the 18-55 but it just isn't fast enough or good in low light, also love my 50 1.8 awesome but not wide enough for so many things. I recently found dust on my sensor and came to the conclusion I switch lenses way too much. I will be moving to FF soon and wonder, what lens would you or could you leave on forever, to cover all situations and not miss any other. I want to purchase that lens and leave it on 99% of the time to avoid contamination, as I am chicken S%&@ and will not clean my sensor. So Everyone, FX, one lens forever, what are you using and why????
Sensor dust is a fact of life, even if you never change lenses. I'm like you in that I hate cleaning my own sensor, I allocate a certain amount of money each year to have my sensor professionally cleaned.
If you want one camera to do it all get a Sony RX10. It'll do wide to telephoto with a pretty fast lens.
That being said, dust shouldn't be too big a deal as your camera probably has a sensor shake or self clean function. For the most part my camera is mostly clean, and 90% of the time an air blower bulb will do the trick. I think you shouldn't avoid the inevitable and just enjoy the camera. Get a Giotto's Rocket Air Blower and enjoy!
Nifty fifty 150% for me on one lens on FX.
You have a great eye bye the way. Keep working on those and don't worry about the gear too much. Pitchblack said it well, as he usually does.
I would buy the 16-35 f/4.0. That will cover most of your landscapes. I would then buy the 50mm 1.4G. It is a good all around lens, is long enough for portraits if they are full body shots and you will get some nice bokeh wide open. This is also one of Nikon's best value lens, better than the Canon equivalent. Lots of people poo poo it but they are usually comparing it to the Sigma Art at double the price. The Sigma is undoubtedly better, but this lens is half the price ($419 vs $899 at B&H) and just as sharp as the 24-70 2.8 at 50mm.
I would then buy the 105 2.8 Micro and use it for portraits and micro. This is not my first choice - I would go with the 105 DC 2.0 or 135 DC 2.0 and 200 f/4 (I own the last two). But money was no object. Unless money is no object to you, the 105 2.8 Micro is a very nice compromise for slightly more than a quarter the price that I chose.
These three lenses combined with a D610 would be a very nice kit for $5,000ish. If you have more money, buy better lenses. I would not bother upgrading the 16-35, but the Sigma Art and the DC 135 2.0 would be worthwhile upgrades. Not sure you need that though.
And don't worry about sensor dust. Go here and buy this if you are really worried:
And go here to learn more about dust in general:
But why not suggest the Sigma 24-105 Art that fits nicely, I would say.
I don't own it, myself, though.
It should get you the versatility and more than decent image quality, but you'll never get close to the f1.8 aperture from this sort of lens.
Sigma 70-200/2.8, 105/2.8
Nikon 50/1.4G, 18-200, 80-400G
1 10-30, 30-110
All zooms - whether internal focussing or internal zooming move air around and so you risk dust on your sensor. TBH if you want to avoid a dusty sensor you should get a compact camera without an interchangeable lens and it should have a fixed focal length lens on it. Such a camera is so far from what I would want that I have no idea if one even exists.
Sorry I can't helpyou more.
In reading other forums, there seems to be a feeling that one should not change lenses unless one is in a over-pressured clean room.
As for cleaning the sensor. I can understand why you would not want to do it yourself. But there are professionals who can clean the sensor... If... it ever needs it for not a lot of money.
I can't tell you how much because I have NEVER had a need to have a sensor cleaned on any of my DSLRs
So don't be concerned with changing lenses. Just take reasonable care. Don't sneeze into the camera. Don't change lenses while riding in the back of a pick-up truck on a dirt road. Don't change lenses in a sandstorm...
DSLRs are delicate but not that delicate.
I looked at the Sigma site on their discontinued list and that lens is not on that list. But it is still on the current lens page and evidently still for sale.
Has Sigma officially made any statements? I have not found anything. I fear that it will be discontinued as it really did not seem to sell well.
If I were looking for a zoom lens, I would have considered it.
The first lens on FX that I kept glued was the 24-70 2.8 it covers landscape and portraits. Had the 70-200mm 2.8 been lighter no doubt that would be glued on to my camera and you can do landscape with it too.
My current lens that is glued to my camera is the sigma 50mm 1.4 art 99% of the time and the other 1% sits in the bag. (All statistics are made up including this one).
I do a little bit of everything and this covers it well but I do change it as necessary.
Also we have a few threads about cleaning materials and how to clean the sensor. If you feel like you need a Camera Shop to clean it then that is perfectly fine too.
Rumor was it was discontinued, then that production was just stopped as they only have one factory and were focusing on making other lenses, now it's that it may indeed be discontinued.
I'm renting a copy of this lens from lensrentals for a trip to Colombia in a week. If I like it enough I'll probably end up using their "keeper" program to outright purchase it.
The 300f4 stays locked onto my 7100, but obviously I'm not shooting panoramas with it. Most of the time you should just think about what YOU will need for the shoot and change lenses in a relatively non-dusty environment beforehand. You may find that the 50 1.8 is wide enough for an everyday lens on FX. The 24-105 is a great all purpose indoors and outdoors lens on a FX camera but is still not wide enough (IMHO, of course) for DX to be an all-purpose, everyday, walk-around lens.
