m4/3 lenses for IR

Dear all,

I've had my E-M10ii converted to full spectrum by Protech (speedy and nice to deal with, BTW) and I'm having great fun playing around, initially with a Hoya 720nm filter.

I've been using the Panasonic 12-35 f2.8, which is widely said to be quite good for IR - it is, but there is a just-noticeable hotspot towards the centre of the frame especially at smaller apertures and with IR-bright elements in the frame. This isn't a major issue and is fairly simple to correct in PP, but I was wondering what other lenses people had tried with success?

My Pan-Leica 15 is better, but I'd like a standard zoom, really, and ideally something wide to super-wide. I haven't yet tried the Laowa 7.5 or Oly 7-14, while the 12-100 is hopeless, BTW.

I've seen recommendations for various iterations of the Oly 14-42 and the 12-50, but does anyone have any experience either way?

Many thanks.

Too much Oly gear.

Assorted legacy lenses, plus a Fuji X70.
