Hi & Happy New Year to all. I've been studying aspects of photography & my D7200 for 2 months, though not shooting much - too cold & and all my shots since going to Manual have been awful - so much to learn (& I get the idea of starting in Aperture Priority & I will use that when the situation dictates, but right now I want to get one good shot in manual - on purpose!!). So since I'm in study mode I wondered whether someone has done a guide / post on lenses that a novice could follow. I'm aware of the uses of some basic lenses types (fish eye, ultra wide angle, wide angle, medium, macro, telephoto / zooms, etc) & what a lens f-number means in terms of speed & DoF). I also get it that some zooms may not be super sharp at the extremes of their ranges.
However I'm unsure how range & maximum focal length affects sharpness (assuming exposure is good & camera shake, haze, fog etc are not factors) and size of subject. For instance a photographer is telling me my 70-300 mm lens is 'OK' as a run-around basic lens, but only between 100 & 200 mm; and if I want sharp images (all other things being equal) then there are 200 mm lenses (eg, 70-200 or 80-200) that will do a far better job. Eg, he is saying the same bird shot at the same distance & the saem focal length will be larger in the frame at the same focal length yet still far sharper than a lens like the 70-300 (and, he says, this means less cropping to see good detail & less PP).
Being a pretty new novice I don't get how a 200 mm lens "zooms" in closer than a 300 mm lens. I'm assuming that's the only way a subject can fill the frame more, at the same focal length, and be sharper, than a 300 mm lens. If you shot with both lenses at their max, doesn't the 300 still zoom in closer than a 200, even if it is a better quality 200?

JD750 made an excellent suggestion for getting to know your camera better. Study mode works best with camera in hand! And Gene51's comments pretty much cover the rest.
I still can find a few things to say!
First, you do not say if your 70-300mm is a crop sensor or full frame lens. Nikon has 5 different versions of this lens, 3 are FX, the other 2 are DX. The use of a FF lens on a DX camera means that your images are essentially "cropped" in camera, while the DX lens will show more of the background. Different "angle of view" is the culprit behind the difference - both have a maximum magnification of 300mm. You can go to Nikon's website and do a comparison yourself of these lenses. [Choose Lenses --> DSLR --> Shop All.]
Second, you state that you would like to acquire more lenses. If you want quality lenses, it will cost more and be more expensive, plus they tend to be FX lenses and heavier than the DX lenses. If you want to own 3 lenses that are considered the most "classic" of Nikon's selection, they are: 14-24mm f/2.8, 24-70mm f/2.8, 70-200mm f/2.8. These three cover all of the basic wide angle up to zoom ranges most people need, and are all pro-quality. For longer zooms, there are a number of lenses to consider. Nikon makes the 200-500mm f/5.6, Sigma makes the 150-600mm f/5-6.3 Sport [better than the Contemporary version], and there are others I am not familiar with. Of course there are really fine prime lenses at all focal lengths, and the longer the heavier and more expensive! So there are lots to choose from.

Hi & thanks for your suggestions. I've shot 7,500+ shots in Auto with the D7200 & another 9,000 with a Nikon 1 AW1 - time to 'grow up!". I'm using AP for depth of field practice in doors & I use the Exposure Metre for every shot now. I've not yet started using Exposure Compensation (it's my next task) - I've been trying to balance ISO, shutter & aperture to get the metre to show correct exposure or one stop over-exposed for snow. At the shutter speed I need to use for hand-holding below freezing, I'm finding it hard to go wide enough for a correct exposure by the metre, because, if I up the ISO much past 400 I get gritty looking shadows (& there is a lot of shadow at 60 North in the winter!!). I also cannot set up the tripod quickly enough in below zero, then frame, the set up for exposure, before my hands are really hurting (cry-baby Aussie - I know - but it still hurts!!). I use the Info button to see settings as I juggle aperture, ISO & shutter speed.
I may be deluded but I do want to get a grip on manual mode. Then I know I can use the others for specific situations & I'll know the reasons for choosing! That's my goal for winter - understand enough to know the reasons for choosing what mode to shoot in for any given shot, and what settings to set myself. To me, the 'why' and the 'how' cannot be separated. Thanks again for your guidance & great shooting!

It is good you are studying the exposure triangle [shutter speed, ISO, aperture], because that is key to understanding all of the shooting modes, but especially manual mode. The more you practice [indoors in the winter, of course!], the more intuitive your settings will become, based on the situation.
Unless you are going to a site where the lighting is significantly different from what you see out your window, you could pre-set so you don't have to do too much of that once you go outside. At least a good starting point. The tripod is nicer to travel with if it is collapsed, but under the circumstances, consider setting it up at home so the height with camera mounted is comfortable for you. Then all you have to do as soon as you get there is spread the legs, mount the camera, make a few adjustments, and point it where you want to take the photos. Do you use back button focus? That can help because you can set focus once at the scene and it won't change unless you want it to. A wired remote can also help with the cold hands because you can keep the hand in your pocket!
I like manual mode, because often I am looking for a different result than the other shooting modes will produce. A test shot when first arriving will help with exposure, which I often find is best set lower than what the in-camera meter says is "correct". As long as the shadows are not too dark, you can get back good detail in post processing. Or you could bracket shots for HDR.
One of our members on UHH, Burkphoto, posted an excellent commentary on why to use the different shooting modes. There is more than what I am sharing here, but this is the most relevant part for now. [I recently asked him if I could pass this on to others, and he said to go ahead.]
You will probably have to expand this once I post it!

Here's a pro perspective:
Every mode on your camera has a definite, legitimate purpose. And every mode has real limits!
You have to understand that every scene has a light level that requires a certain exposure. Your metering technique must be good enough to balance sensitivity (ISO) with exposure time (Shutter Speed), and the volume of light flowing through the lens (Aperture). For a given scene and ISO setting, you need a given size "bucket of photons."
Your meter is dumb. Stupid. It wants to see EVERYTHING as middle gray. If you meter a white wall, and set exposure blindly for that, you will get gray. If you meter a wall painted flat black, and set exposure blindly for that, you will get gray. So in difficult conditions, use an exposure target and white balance tool such as a Delta-1 Gray Card, or ExpoDisc, or One Shot Digital Calibration Target.
Oh, there are various matrix metering modes designed to give you a great exposure of "most" scenes, but they can all be fooled under certain conditions.
Manual exposure modes work best under stable, controlled lighting conditions, where the scene brightness range is limited to around 5.5 f/stops. A great example of this is an office or school classroom lit with 2'x4' fluorescent troffers. Another great example is a portrait setup with fixed lighting, used to photograph hundreds of school children. Another great example is a light tent used for product photography of small items for a parts catalog.
Program mode works best when you need to work in changing lighting conditions. If your camera has Program Shift capability, you can change the combination of aperture and shutter with the flick of a dial. The exposure remains in balance, but the aperture closes down as you slow down the shutter, or the aperture opens up as you speed up the shutter.
Aperture Priority gives you a fixed aperture and lets the shutter speed float with the light level. This is so you have absolute control over depth of field.
Shutter Priority gives you a fixed shutter speed and an aperture that varies with the light level. This is so you can use a speed that stops or blurs action.
Manual Mode gives you fixed everything... ISO, Aperture, Shutter Speed. This is so you can make a series of exposures that are all the same, provided the lighting is fixed!
There are many variations on these, of course, depending on your camera's features. If your camera has Auto ISO, it may be combined with other modes to really confuse things! (Just kidding. It's helpful, too.)
