>>3161636and this is what it looks like at anything over 75mm, i'd say it might be usable in certain situations, maybe if you're shooting a dark protrait or whatever...
i cut the lens just after i bought it for 100 usd a couple years ago and planned on using it on film cameras, back then i didn't have any FF digital cameras, it worked fine and used it for a few things
it's also interesting, you can see the circle move when IS is engaged and also when the focus distance changes
