Has anyone tried this combo? how it works? I've read that can be used without the apsc cropping just removing the internal baffle... Question

It works great in a crop mode,like all other DN Sigmas that I have - 19/2.8 and 60/2.8.Even the largely postponed 16/2.8 looks much better on the A7 that on croppers.Image circle of the 30/2.8 is quite large and covers nearly the whole of 24x36mm format,so by removing the rear plastic mask one can get FF coverage with darkened and softened corners.

I've tried to remove the plastic baffle, the vignetting is too strong for my taste, I've sold it Wink

Same here, I tried it and whilst very sharp, the vignetting is too high, meaning you have to crop quite a lot of the image away.

I'd be surprised if Sigma decided to make fe lenses. The market is too small.
