macro - Why won't Nikon B700 focus close when fully zoomed?


Hello recently I went to best buy and played with a Nikon B500, it was great. I was able to focus on the smallest things, close or far, zoomed all the way in and all the way out. So I went on the internet and found out that the B700 shoots in raw so I got it instead thinking it was better. Only I cant get it to focus on anything close up, weather in macro or not after like 25% zoom it no longer focuses on anything no matter what settings I put it on leaving me to think that I should have gotten the cheaper B500. It may not shoot in raw but at least it would be usable. I am fairly new to photography I had a friend with much more experience come over and try to figure it out. He told me that my camera has a range that it is able to focus on. Only the cheaper B500 focused on things way more zoomed in and with the camera much closer to the object so it doesn't make much since to me. So my question is why wont my camera focus on macro shots (weather in macro or not)?



Answer



Just because one camera is more expensive than another does not mean that it will be "better" at every conceivable metric. Especially with fixed lens compacts, the camera is designed around a purpose that may or may not include what seems to be most important to you: macro capability.


In the case of the B500 vs the B700, the greater "zoom" of the B700 makes it harder to design a lens that can shoot at close distances than the B500. Compare the two lenses:




  • The B500 has a 35mm "equivalent" 23-900 mm F3.0-6.5 Zoom Lens that can focus as close as 11.8 inches

  • The B700 has a 35mm "equivalent" 24-1440 mm F3.3-6.5 Zoom Lens that can focus as close as 19.7 inches.


So although the B700 costs more, has more megapixels, more "zoom", a higher max video resolution, faster frame rate, can save raw files, etc. it doesn't focus as close as the B500 does.

Why is the front element of a telephoto lens larger than a wide angle lens?

A wide angle lens has a wide angle of view, therefore it would make sense that the front of the lens would also be wide. A telephoto lens ha...
