I am not a pro, so I wanted to get a heads-up before purchasing. Basically I wanted to know the differences these lenses have, features, and more of a better zoom lens. Any help is appreciated!
Pros of the 55-300mm Less expensive Smaller/lighter Wide-end of the lens goes to 55mm
Cons of the 55-300mm In the future, if you buy a full frame Nikon, this lens would only work in DX crop mode which defeats the purpose of the full frame sensor. Front lens element rotates on focus (i.e. interferes with use of certain filters). No manual focus override (i.e. must manually toggle switch to turn the focus ring). VR is either just on or off.
Pros of the 70-300mm Theoretically sharper on a DX camera relative to DX lenses (negligible)* In the future, if you buy a full frame Nikon, you can still use this lens. Front lens element doesn’t rotate on focus. Manual focus override. VR differentiation between Normal and Active.
Cons of the 70-300mm More expensive Larger/heavier Wide-end of the lens only goes to 70mm
Between these 2 lenses, I think the 55-300mm is the obvious choice for you. The biggest reason to get the 70-300mm would be to future-proof yourself if you buy a full-frame camera (e.g., D610, Df, D750, D810, D4s). If I’m being honest, when you realize you need a full-frame camera, you’re highly likely going to want to get a more pro tele zoom lens.
* The center of every lens is generally the sharpest so using an FX lens on a DX camera would theoretically give you sharper results compared to a DX lens. This is because the FX lens is designed to cast an image circle that covers a full-frame sensor. Since the DX sensor is smaller, it’s only capturing the center part of the lens. So it should be sharper compared to a DX lens (which casts a smaller image circle). I would say this is probably a negligible point and the advantages of price and weight/size are far more significant.
As it happens, I have the 55-300mm lens, and find it pretty satisfactory. I should say that I do not do fast-moving sports and the like, so its relative slowness is not a big factor for me. It is light and sharp, and the range is good. I got mine with a big discount when I bought my D3200, and my wife got the same lens slightly used as well for her D7100. We have found it works very well, providing decent and sharp images. We both took our new digital cameras to the Galapagos this spring, and were quite satisfied with the results.
The focus speed of the lens is not terribly fast, but it works well enough for most purposes. Some of the issue is with the camera rather than the lens. The D7100 will catch birds in flight and the like better than the D3200 with the same lens.
Of course one's mileage will vary, but I think the 55-300mm is a good complement to the 18-55mm with no gap in coverage, and with similar performance. Optically it is quite decent, and it's compact enough to carry around comfortably; a good traveling lens. Though it does not focus very close, one can get pretty good sized images of small things at 300mm.
Both lenses have similar aperture sizes, so you don't gain any optical speed with the more expensive lens. If you're planning to stick with DX, the 55-300mm will serve you well. If you eventually graduate to FX, there's a good chance one of your needs will be faster glass, and in this case, the 70-300mm will not satisfy anyway, as ohyeahar suggests. Pros, and those shooting sports routinely, almost always want faster lenses than either of these.
One thing the 70-300mm lens does have that the 55-300mm does not is a non rotating front element. This is not a big deal most of the time, but the 55-300mm and the 18-55mm cannot readily be used with a polarizing filter and AF on, because a polar filter requires a specific rotated position; even a slight AF adjustment will change it.
Other than that problem, I think the 55-300mm is a good bargain, and it will make good, sharp pictures throughout its range.
