  • Yes. Your 70-200 f/2.8 will be converted to a 98-280 f/4.0. On the D7100 this will give you an angle of view like a 150-428 mm lens on FX. (The DX  sensor linear size factor is 1.53)
  • The 24-120 f/4.0 has VR Active mode in addition. This is convenient when shooting from a moving vehicle, boat or small airplane; when the movements are larger than normal. For normal use the two ...
  • I am not a lens tester. I own and use both lenses. Historically I first purchased the 24-85. Over some time I was missing more range at occasions so I bought the 24-120 in addition. If I want to ...
  • Bring the following: A good pair of binoculars (for each person). Camera (your D7100). Spare batteries (perhaps 2 extra). Charger for batteries. Plenty of spare memory cards (you should have an ...
  • I suppose you are asking about the D800 and D810? The D810A is designed for astro photography. In addition we have the D800E just to make things slightly more complicated. The D800/D800E were ...
  • Nikon makes AF-S 20/1.8, 24/1.8, 28/1.8, 35/1.8 and all will work very well on all Nikon DSLRs. The new DX 16-80/2.8-4.0 E is also worth looking at, imho.
  • Last year I visited Tanzania bringing a D500 and a D810 together with some lenses. This was my first trip shooting wild life with the D500. In the first place I planned to use the D810 with my ...
  • I believe this lens will not AF on the D3200. It need a camera with built in AF motor. Look for an AF-S lens.
  • Ken Wheeler, with his nick name Theoria Apophasis and also called the angry photographer (TAP), produces a lot of videos of which 100 % is nonsense. Many of these videos are about lenses and ...
  • The following Nikon DSLRs will handle E lenses: All FX bodies, D500, D300/s, D7xxx, D5xxx, D3400, D3300, D3200, D3100 The following Nikon DSLRs will handle AF-P lenses: D5, D810/A, D750, Df, D500, ...
  • It really depends on what you mean by equivalent look. Often we would think of the perspective which is determined by the distance to the object. Then of course, the field of view (FoV) which is a ...
  • It looks like you are using the center spot for focusing. In the first image focus is better on her left eye and this eye is close to the center of the image. In the second she has her face ...
  • Years ago I often brought a 24 or 35 and 85 or 105. The 24/35 would enable an overview and the longer lens picking out some details in the area, which could be a person (portrait) or something ...
  • Replied in Camera type.
    There is hard-selling of a Sony bridge camera with overkill superzoom from nafik in this thread. While a bridge camera could be OK for a lot of people there are weaknesses too. First of all AF is ...
  • Where in Africa are you going? How are you going to travel when seeing the animals; type of vehicle and how many people in each car (will there be space for extra camera floating around)? What ...
  • Replied in Nikon lenses
    In this list you can find a lot of information about Nikon lenses: http://www.photosynthesis.co.nz/nikon/specs.html If you click on DX to the left you will jump down to the DX lenses. Then for each ...
  • I just had a look at my old Nikon 24/2.8 from 1971. I mounted it on a D810 and looked at building details through the viewfinder. (It is Ai-ed later on.) To me it looked surprisingly good ...
  • The D80 is a good camera. However, cameras in 2006 had limited high ISO capability. The ideal replacement would be the Nikon D7200 which has ISO all the way up to 102 400, compared to the D80 ...
  • The 18-70 will work very well on a D7200. Actually images will be better due to the higher resolution of the D7200 sensor. Still the new 16-80 E will be a significant upgrade over the old lens. ...
  • “Aperture size and reproduction” is an approximation which breaks down under certain conditions (but still you need to determine what coc to utilize). Calculated DoF depends on 4 factors, but it ...
