Good for the value, some vignetting
The "lock-open" ring doesn't seem to do a ton and is easily mistaken for the aperture ring if not looking. Luckily my lens fits very tightly, so I'm not real worried about it falling off should I turn the wrong ring, lol.Great for the price, but there is a fair amount of vignetting on my 28-70 FD mount I bought this for to have a wide angle on my A7S. Goes away after about 50mm,
