In body filters

Hi Paul,

have you already had a look at Kase filters? They have a product line called magnetic round filtes. These are round. Very easy to use. Not cheap, but how often do you buy filters? I got that tip from a landscape photographer on youtube. I bought them for me in size 77mm (biggest lens I have) and use adapters to get to that size with each lens. Easy to use, easy to carry around.

Like we said, the Sigma has a rear filter holder.

Another option perhaps is to go for this, with the older 12-24 f4 for Canon EF. It's an EF to L-mount adapter with a built-in variable ND.

Some time ago I had a look at this adapter, which is a creative solution. But for my use there are two problems.

1. It's always active, with a minimum 2 stop ND.

2. I would have to use Canon lenses.
