Drop in Filter for the 100-400mm f4.5

[Randy@PodolskyPhotography]

I'm looking to replace the clear 40.5mm filter in my Sony drop-in holder with a quality circular polarizer instead of buying the Sony VF-DCPL1.

Has anyone done this on the Sony 100-400 GM? If so, what 40.5mm CPL did you go with, and are you happy with it?

I'm just looking for a high-quality filter that fits and performs well. If the consensus is that the Sony VF-DCPL1 is worth the extra money, I'd like to hear that too. Thanks!

I believe all the Sony lens which take drop-in filters use the same size (from memory, that’s 600 GM, 400 GM, 300 GM, and now 100-400 f/4.5 - are there any others?) - the compatibility page for the Sony drop in circ-pol shows it is fully compatible with all 4 lenses.

I haven’t bought one yet, but a quick google didn’t show me any third party solutions - Sigma make one, but it appears to be for their 300-600mm lens.

The drop in comes with a clear 40.5mm. I’m hoping to just buy another 40.5 CPL, unscrew the clear and screw in the CPL. the Sony CPL (expensive) includes the drop in tray which I don’t need “if” I can just replace the filter itself.
