Can a camera half frame lens be converted to a full frame camera?

Generally, it can't be used, the lens will block the reflector, and as for what black edge cropping, I'm afraid no one has done this.

No problem at all.

Due to the large imaging circle of full-frame lenses, the biggest advantage of installing them on APS-C format cameras for those entry-level full-frame lenses is that they can basically avoid the edge parts of the lens that are relatively poor in imaging, and only use the ** part of the lens, which may have certain advantages in imaging.

Because full-frame cameras produce lenses with an image size larger than the photosensitive area of half-frame cameras, they can be used in half-frame cameras. However, at this time, the imaging of the peripheral part of the lens exceeds the edge of the image sensor, and the image sensor only obtains a smaller part of the center of the lens image, and the angle of view of the lens imaging becomes smaller; However, since the APS-C format camera sensor is smaller than that of full-frame cameras, and the equivalent focal length is larger than that of 135 cameras, the actual focal length is only after the conversion of the focal length conversion factor. Generally speaking, the conversion factor of Canon cameras is that its full-frame 50mm prime lens is used in APS-C format cameras, which is smaller than the 35mm prime head of general APS-C format.

If it is a lens of the same type of mount, the full-frame lens can be used in the APS-C format, and it can be used in mirrorless or 4 3 cameras, and most of them need to be adapted. Because the full-frame image field is large, when used in the APS-C format, only the surrounding areas will be lost, and the image will not be complete.

In addition, the full-frame mirror box is relatively large, and the APS-C format lens is relatively compact, so it is likely that the rear mirror group will conflict with the mirror.

Absolutely. As long as the mount is suitable, it can be used. Be careful, though, that he will have a conversion factor. Generally, it is a multi-focal length lens, mounted on a half-frame camera, and its viewing angle is equivalent to the angle of view of a full-frame 75mm lens.

If the mount of the body and lens is the same, it is definitely possible. If the mount is different, it depends on the specific situation, such as a full-frame SLR lens, if you use an adapter ring, it can usually be transferred to a half-frame mirrorless body with other mounts. However, full-frame mirrorless lenses are usually not easy to transfer, and it is common for Sony mirrorless lenses to be used on Nikon mirrorless lenses.

Full-frame lenses can be used entirely with half-frame cameras, with the only requirement being consistent buckles. However, the angle of view of the lens attached to the rear of the half-frame camera decreases and the equivalent focal length increases, and the equivalent focal length conversion factor of full-frame lenses from Nikon, Sony, Pentax, and Fujifilm, e.g., the equivalent focal length of a 50mm lens means that the angle of view of a 50mm lens will be the same as that of a 75mm full-frame lens. Canon full-frame lenses have a special equivalent focal length conversion factor for:

A full-frame camera lens is perfectly fine for half-frame. The format size of a digital camera refers to the size of the CMOS. Full frame refers to 36 24. Half frame is exactly half of full frame, which means that his CMOS is half of full frame.

The bayonet can be used directly, and the bayonet can also be used if there is a corresponding adapter ring.

OK. 1. Half of the body with a full lens, of course, the effect is very good. Half of the frame is only half of the effective imaging circle of Wu Yanyin, who uses the full-frame lens. Therefore, the vignetting phenomenon that occurs in the full width is much weaker in the half frame.

Second, the so-called full-frame is for the size of traditional 135 film. In the past, most DSLRs were smaller than the size of 135 film, but the size of the CCD (or CMOS imaging element) of a full-frame DSLR was the same as that of 135 film. And the larger the CCD size, the higher the image quality.

And for hail skin users who already have a traditional cavity SLR, there will be no conversion problem with the use of lenses.

3. For non-full-frame cameras, the CCD size is about 2 3 of the film size, and a 100mm lens becomes a 160mm lens after conversion magnification. At the wide-angle end of 24mm, the full frame is more advantageous, and the vision is very wide, while it is very embarrassing to use in the full frame, which is equivalent to 38mm.
