As a photo enthusiast who turns every dial and pushes every button on a camera - often inadvertently - I am keenly aware of the harm that I can do to my images.
This becomes evident when I use one of the lenses that the Fujifilm system makes on a standard camera. It's the
27mm f:2.8 pancake lens - the original one with no aperture ring. I keep examples of this on X-T10 and X-E2 camera bodies and use them all the time ( Love the convenient size for reportage or mini-studio shots. ) All is well in the aperture line as long as you control this from the thumb wheel. All the apertures plus ' A' setting right next to f:16... and that's the problem...
Right next to f:16. One fat thumb's click too far and I'm not at the aperture I expect for depth of field - I'm at whatever the camera wants to set. This can be infuriating if I lose the DOF I need. And even worse, if the camera makes a better decision than I did. It's like hearing tooth-sucking from the ranks.
But if I were to use a new
Sigma 35mm f:1.4 DG DN Art lens on another camera I would be in command again. As well as the more esoteric commands that the lens will respond to, it has an aperture ring that has all possible options built in.
a. Clickable stops - part stops in between the main stations on the line.
b. No-click setting for video workers.
c. Lock
into automatic mode for control of the aperture from the camera - either the program impulses or wheel control.
d. Lock
out of automatic mode to prevent unpleasant surprises. You're always in control.
This is a lens that can go for several mounts; L mount and Sony E mount at present*. The build quality of the barrel and reported performance of the optics are excellent. It's apparently lighter than its predecessor in the Sigma line.
Thanx to Sigma for the fine heading image.
*May we hope for more?
