Are the Full Spectrum conversion images as sharp when using correction filters on the lens, as opposed to a more conventional single wavelength IR conversion?

No, they are not as sharp.

When a camera is sent for IR conversion, the work is done by professionals. Usually, they ask the camera to be sent with its lens in order to adjust things perfectly. So the IR conversion is custom made.

When a full-spectrum camera is bought on eBay (like mine), that's just a regular colour camera whose UV-IR filter was taken off. That's why these cameras are always cheaper.

The result is a few surprises. My Lumix 20mm lens is unable to focus; so I'm using it manually.

My preferred IR zoom (on previous IR cameras), the Lumix 14-42mm always post-focus on my new one; so it gives slightly burred photos.

On the other hand, my Lumix 14-45mm seems to give perfect results.

It seems like Full Conversion has gotten popular.

Full spectrum IR cameras are more popular because we are discovering that we are not limited to B&W conversion or channel swapping during post-processing. Using filters, we can create photos impossible to do with a cell phone.

…I've introduced the Candy Pink IR Photography. This time two filters are needed:
• a yellow-green filter (Лomo ж3-2*)
• a cobalt blue filter (B+W KB20).

I'm still experimenting. Candy Pink Photography can still be improved when we add a third filter, a blue 80A:

Pink Grapefruit IR is the most difficult to achieve. It doesn't work under a cloudy sky and for unknown reasons, it may work or not.

On the contrary, Candy Pink IR photography works under any temperature and at any time of the day. It's very predictive.

When saturation is boosted during post-processing, Pink Grapefruit IR becomes orange and Candy Pink IR photography becomes Scarlet IR photography.

So this is room for a lot of experimentation.
