Dedicated fisheye conversion lens for the FE 28 mm F2 provides 16 mm focal length with fisheye perspective and a full 180° angle of view (diagonally). The converter has been specifically designed for the FE 28 mm F2, and therefore offers expressive fisheye perspective with excellent image quality from infinity down to the closest focusing distance, without compromising the basic image quality
The APS-C CoC of 0.02 produces a depth of field of 16.19″. The APS-C image with the same lens has a shallower depth of field, weird right? A 50mm APS-C lens will have a cropped field of view of 75mm. If you compare a full-frame 24-megapixel sensor to a 24-megapixel APS-C camera shooting the same image at the same distance.
So, as other are saying, a telecompressor is specifically for use on full frame lenses and APS-C camera body. You don't need the speed increase with a full frame camera, just use the lens natively (with a Metabones, or equivalent Canon EF to Sony E adapter) since the larger sensor offers this same "speed" boost by being able to shoot at higher
GF 63mm f/2.8 // FF 50mm f/2.2. GF 110mm f/2.0 // FF 87mm f/1.6. GF 120mm f/4.0 // FF 95mm f/3.2. So, there you have it. You 50mm junkies will need to get your hands on the 63mm lens, the bokeh
The 'crop sensor' crops the angle of view, compared to 'full frame'. A 35mm lens on an APS-C camera gives a similar angle of view to a 50mm lens on a full frame camera (a useful general purpose lens). A 50mm lens on an APS-C camera gives a similar angle of view to an 80mm lens on a full frame camera (useful for portraits).
I decided to take a poll to find out what other MFT users were doing. Online poll. 50% of the MFT users convert their numbers to FF-equivalents. Remember, this was in a MFT user-group. I have a hunch that I would get different results in APSc user groups…. If 50% of the group is doing it, these users may consider the full-frame as a standard.
