Sharp photos are not strictly a lens problem. Its like shooting a gun. Anyone can shoot one but if you don't have the right shooting techniques you will never be a good shooter. To get the sharpest photos you need: a sturdy tried and true tripod not the Walmart variety; you need to lock up the mirror because camera shake can effect sharpness; you need to use a remote shutter release not one on camera; you need to have special optics that resolve distortion or minimize it; and you need to use the optimal F stop or aperture since it will affect sharpness.

I assume from your posting you do not have or know about these things. It would be fair to assume that you do not know what the optimal aperture is for the lenses your use for their focal lengths since the lenses you are using have them and still produce sharpness. In fact I use one of them myself and it's sharpness is excellent.

Hope this helps.

I agree with you! The camera though is only as good as the abilities and experience of the user, photographer. And if one is never going to use some of the abilities of the D850 say over the D810 why get it. It is why I did not upgrade and to me the money is not the object. In fact I am thinking or going medium format or maybe DSLR Leica.

My daughter has the very same camera as you. There is nothing wrong with it. And it does without some form of help and practice have a high learning curve from where you are at.

I always believe that the reasons why one should always upgrade camera are mainly four-fold: (1) The technology in your camera is so old that upgrading would be a benefit to your photography; which is not your case since it is one of Nikon's newest camera; (2) . You have advanced so far in your photography skills that an advanced camera would enable you to best further your ventures; (3) The type of photography you want to do involves inclement weather, temperatures, or conditions where a weatherproofed or better constructed camera is necessary against these hazards. Keep in mind none of the present weatherproofing or waterproofing cans seal a camera better than an underwater camera housing, but that is only for underwater photography. (4) You need a camera with high motor drive capabilities for sports or need a camera for high meta-pixel (MP) for extremely large blowups like some photographers need for their jobs.

BUT, keep one thing in mind! Regardless of how advanced a camera is people shooting with a camera as simple as yours and win many photo contests even sometimes over the pros! A real photographer knows that a camera is only a tool, the photographer is the person really responsible for the photograph which is why people with entry cameras or enthusiast camera (Nikon D7200 or D7500) also win many contests too. That also goes for every brand's entry level cameras. If you don't believe me start reading Photography magazines or read contest results. There more to having a certain camera rather it's about the photographers capabilities and the lenses he uses.

Hope this helps.

There's a lot more that goes into your question than what you are asking. All lenses are not equal due to the quality of the lens. Nikon, Canon, and Sigma have lenses that have some very fine lens elements/optics which contribute greatly to lens sharpness, flare, vignetting, etc. But you have to be willing to spend the money. Sometimes you can get a lens that might be a lower cost lens where the optics are outstanding but the lens materials may not be as good. Also as the aperture increases(largest) in size: F/2.8, F/1.8 and F/1.4, etc the price goes up sometimes a lot, but this depends on the type of landscape photography you are going to do. Is it going to be night landscapes? Then too as one mentioned in this forum you have to consider that the optimal aperture is for each lens. Each lens has one and it is based on what has been determined by testing or actual use to be the sharpest and distortion free aperture. And that is not always the largest aperture. You will find in many cases it may be F/2.8, F/4 or smaller. This will sacrifice in some cases your lens low light sensitivity, but this can be offset by the time you allow light to enter into the lens at the smaller aperture. But that comes with increase in noise which can ruin a photo if too high. Last, but not least each wide angle prime has it's special uses, for example astrophotography requires a 20mm or better, thought some other can work again if you want more noise or distortions, as do all wide angle lenses greater than 35mm for the most part.

One more point to consider are the usually higher priced zoom lenses that cover a wide angle range. But that depends on the type of photography you are using for landscape like depth of field and broken. Some of these lenses from the manufactures I mentioned have terrific optics and can obtain just as good photos as a fixed lens, although there is a lot of debate out there on this based on personal photographer experiences. And then too a top quality wide angle zoom like I use can cover a lot more varieties of landscape without limiting you or forcing you to move all around and also leaving one less lens to carry especially when traveling and weight can be a concern.

I may have given you a lot of advice, but it is based on the possibility that you are not beyond a amateur or beginning photographer based on the wording of your question. Otherwise all this information would have been known to you. Last, but not least do your research between lenses.

How about Affinity HDR very easy to use and low learning curve.

I post this question for discussion for those beginners in photography regarding upgrading cameras. This is based on other questions I have seen posted on this site. I understand everyone has the opinions and there are those who have to have the best. But I always look at this question based on your level of photography expertise. I have gone thru the process and I am glad I had a professional to work with. I had the opportunity in my time to learn from photography instructors, professional photographers, and Playboy. It really does make a difference!

For example a person has a Nikon D7200 and is thinking about upgrading to the Nikon D850. Money is not a problem. So what do we tell him that is realistic and best for him?

Since this person has said money is no problem why not just tell him to buy it since he can grow into it even if he does not have the experience, skills, or needs the abilities the new camera offers him for what he wants to do with it. Heck why not just tell him to buy a Leica or the medium format cameras. But?

The one thing every photographer knows is that an amateur or beginner has to start somewhere. While camera are so smart they basically become a high price fix lens rangefinder camera with the professional look. Therefore until the amateur or beginner has the following I do not recommend going into the high priced cameras: 1. Developed level of photography basics through some on hands training with another experienced photographer. 2. The photography he is going to be undertaking or specialize in needs an advanced pro level camera. 3. And he is willing to spend the money on the level of glass or lenses that support that camera to its fullest.

After all why spend money on a 44 Magnum when the 9mm can shoot more rounds more accurately and be just a deadly. Maybe because you want to be the big boy on the block. But in real life shooting cases the 9 mm for rounds on target accuracy would win out. Don't forget the other guy will be shooting at you.

So much the same with photography in a way. Right now I own a Nikon D810 after owning since 1973 a variety of Nikon and Canon film, FX and DX cameras; from the very expensive to least. I know that the camera doesn't truly make the photographer but his skills as such. A entry level DSLR can win photography contests just like the professional cameras, and that is a fact.

So I ask myself should I upgrade to the D850? My answer is NO. Why you ask? Because I am a landscape photographer mostly, do not take astrophotography, but still could with the D810, do not really need the extra MP, don't need the little faster motor drive, etc. So for me I will wait for something else to come along. Here I am looking a my needs as a photographer ever though I could buy the most expensive camera in the world; though it would not make me a better photographer. I could go on with other points that I think others to this forum could make.

SO, What does everyone else think?

I have been in Photography for over 40 years and I can tell you what I have learned about lenses, both Canon, Nikon, et., and then third party such as Tamron, Sigma, and Tokina. Everyone has their favorite lens manufacturer. That doesn't mean it is right for you. The most important things I have leaned are: 1. With the computer age we are in optic development has brought up third party optics/lenses to equal quality of Canon, etc., with the exception of some of the very expensive $2,000 of the top of line Canon, Nikon, etc., lenses. And then again there is not much difference depending on the particular lens. So I am one who does his research. This is all over the internet and it is for the most part easy to understand. Also whenever possible go to a camera shop and try some on your camera. It can be a great lens but it is either too heavy or clumsy on your camera. One wants to avoid these things when possible. You want photography to be fun unless of course you are a professional photographer. Hope this helps.

You are dead wrong about Canon Lenses. They L Series lens will beat anything Tokina or Tamron can put out, but you have to be willing to put up the big money, especially when you can buy expensive cameras.

Over the years I have used Tamron and Tokina lenses on Canon and Nikon cameras without any problem. Just have to be careful the lens works for the camera you want. I did have one problems with a Tokina lens. Also companies like Canon and Nikon will warn you that if it is determined that the 3rd party lens you used caused damage to their camera, on warranty or not, they will not repair it for free, but it will cost you the full price of repairs. Does it happen sometimes, but the risk is on you.

Any entry level camera from Canon, Nikon, Sony, Olympus, etc will work for what you want. Go to a photo shop where they can explain each one for you and the zoom lenses they offer. You do not need to spend big money since it appears you are an amateur. Anyone that tells you different is wrong. When you get more advanced you move up. I have been a professional and travel photographer for over 40 years and myself started with an entry level camera. Any pro will tell you the same thing. Good Luck.
