Nikon clip in filters for FF

[casstony]

I'm wondering what full frame clip-in filters are available for my D750. I see an Optolong L-Pro and STC Multispectra.

Any recommendations?
Any issues using these filters with lenses?

I have the STC MultiSpectra for my D810A. I do have to mirror lockup to install if, so effectively have to use liveview (which isn’t a problem cos I use that for focusing anyway).

The clip-in does vignette (which to me a little too dark that flats can’t fix). But I just crop to an equiv of or just a tad larger of APS-H size.

I’m out right now but I’ll see if I can attach a sample later.

Thanks for the info Sean. If you've got a sub or stack which shows the vignetting I'd be interested to see.

Here's a sample I took (which I posted on CN (https://www.cloudynights.com/topic/643481-h-alpha-clip-filter-options-for-nikon-d810a/?p=9031054)). It is strange that the vignetting is on only 3 borders rather than all 4.

P.S. A little more info here too: https://www.cloudynights.com/topic/571418-new-clip-in-lp-filter-available-for-canon/?p=7900327

That's fairly serious vignetting. I might stick with other options such as 2" filters where they'll fit in the image train or front of lens filters.

I have to say I’ve only used the clip-in once myself. It’s not ideal if the full frame is in use. However if one were to use wide Nikon lenses where cropping is needed anyway due to coma from the lens, etc, then maybe the clip-in may still works fine - so it kinda depends on application.

Tony,

Just saw this today. You may be interested as it’s clip-in filters for the D750 :-

It seems that maybe the Optolong clip-in’s may not vignette as much as the STC DuoNarrowband did for my D810A. However the video does discuss about other caveats with these clip-in filters (especially with wide angle lenses).

[casstony]

Thanks Sean, it does seem that the Optolong doesn't vignette as much.

For wide angle lenses at least you can drive out of town with minimal gear where you don't need a filter.

Are they all that expensive

[casstony]

They're not cheap, about US$230.

Search, I posted a review on stc long ago.

Thanks Steve, easy to find in the 'threads started by Sil' list :)

The apparent difference in vignetting between STC and Optolong is a factor steering me towards Optolong. They will probably release an L-enhance version at some stage.

The addition of the clip-in glass would help to compensate for filter removal from the modified camera too.
