Be careful: in 10-14 range the rear lens is in reach of the mirror :)

Where did you find that much sharpening? How did you process it? A lot of it looks like phone footage.

But the use of a 10-18 lens with crop mode is interesting to me, I have been considering getting one of these lenses for that purpose.

Yeah, too much artificial sharpen, aliasing, contrast and saturation. Also, the shutter speed is too fast.

I have the impression that 'normal' wide angle lenses for cinema is bad... unless you require it. These lenses normally have more distortion and this crispy digital-look (which is why I personally like to use old lenses). I have heard good things about about the Rokinon Cine, though. Maybe with a diffusor filter like Black Promist it will render very nice images using crop mode...
I still think some old lenses (the good ones, like Zeiss Planar 50mm) and a speedbooster will give more cinematic images.

I'm actually curious. I thought EF-S lenses couldn't fit on full frame cameras. How did you do that? Did you have to modify it? Does the aperture control still work? This is potentially game changing for crop mode.

Sometimes you have to cut off some plastic to get them to fit.

I have a tamron 10-24 EF-S and it's definitely fitting inside my mark III.

I could take shots, but before reaching 16-17 I could see the black circle all around the photos, so I did use it but never under the aperture of 16-17 mm.

Today I'll try to make a raw video with that one, at 10mm / crop mode / whatever setting I can find which is working and not showing a black circle.

The crop mode on ef-s lens mounted on full frame look like a cheap trick but it may allow me to shoot nice wide videos with a cheap lens I already own.

Wait and see !

It's working like magic:


I really like this hack, I'll have to play with my old EF-S lenses :-D

Nice! Thanks for sharing. I wonder how it works on EOS M with a speedbooster in crop mode.
