    Good afternoon, experts. Please help with advice. I want to use my sprinkled Nikon D7000 to measure the exposure for Zenith ET. What is the exposure ratio between the cropped matrix and the full frame?

      The size of the matrix does not affect this.

    Good day! I can’t find a definite answer. For example, I put on the crop lens from the FF 70-300mm, will the focus be 105-450mm?
    and on many trading sites with photo equipment they write: approx. NIKON D7500 \ DX \ focal lens 18-200mm \ DX \, 35mm equivalent film will be 27-300mm.
    Nikon AF-S DX NIKKOR 18-105mm f / 3.5-5.6G ED VR Lens: Focal Length

    18 - 105 mm; Equivalent focal length (35 mm)

    27 - 157.5 mm. ???????????

      The focus will be the same. The focal length is written on the lenses - this is the characteristic of the lens. And by multiplication, an ether is obtained - an equivalent fr. Lenses 70-300 for crop and ff will show the same on the camera

      The equivalent focal length is like indicating the price of one product in one currency. To have an understanding of how much this is, the price of 1 kg of bananas in Thai baht, Japanese yen, etc. If you write, 1 kg in Thailand is the equivalent of so many dollars (rubles), it will immediately become easier to calculate the costs, otherwise you will have to calculate everything with a calculator.

      That is, the equivalent focal angle is the angle of view that you get by shooting at the same focal length for a full frame. There is such a phone - Samsung Galaxy S4 zoom. Its lens has a focal length of 4,3-43 mm. And what does this information give us? It is necessary to find out the physical size of the matrix, calculate the equivalent through the calculator ... And so immediately in the review indicate the equivalent focal length - 24-240 mm. And immediately there is an understanding of what angle of view we will have during shooting.

    since childhood I got used to the picture of 58mm and F2 lenses, and therefore when I bought a digital crop camera with a 50mm F2 lens, the focal length obtained on a 80mm crop camera was terribly annoying. To make the picture look similar, you need to use a lens of about 30mm with an aperture of F1.2, which would be very expensive. and still, due to the different focal lengths, the picture will be 50 mm better due to the greater blurring of the background. As a result, I switched to full frame and my old 50mm lens. Everything fell into place!

      "Anyway, due to different focal lengths, the picture will be 50 mm better due to the more blurring of the background"

      Will not be. Wanguyu, by blurring the “background” you would not distinguish 30 1.2 on a crop from 50/2 from a full frame.
      In any case, 50mm on any full-frame system costs much less than an autofocus light thirty, that's right.
