I have this old K-5IIs hanging around, found it sealed up in a bag with a load of silica gel.

Perfect condition, excellent camera, but they don't sell for much used, so . . . .

. . . have requested a couple of quotes for infrared conversion. Thinking 665nm filter but if anyone has any experience of this, advice greatly appreciated.

Here's a quick guide to the different filters available.

M....this is a fascinating newer field of digital photography! If your camera is easily converted

then why not do it asap! I have an old Lumix stashed away collecting dust atoms and it hasn't

had a frame shot through it in about 5 years....antique FZ-20 it is...and I'd like it converted to

NIR...near infrared.

here's a couple links I have in me bookmarks that may interest you since they interest me

heaps....

OK it's 4 links...hah!

Do a Google Search using "Near Infrared Photography"...without the

quotation marks...there's heaps of stuff out there. And also do a search

with just Near Infrared....even heaps more.

Plus here's a couple net pix...to wet your interest....

Let me/us know how you get on with your conversion.

One more link here with some really neat pix...all in the near infrared spectrum...

And I reckon LOS could be a great NIR photography venue...think of the possibilities!

I think 665nm gives the most flexibility in post with channel swapping.

Yes going to get this done this week.

Hey Sunshine, why not get your D7100 done instead?

Here's a good link for how all this works, especially in post . . .

Click on the pictures in the link and a drop down appears showing which filter etc. You can also download the RAW file to practice on in post.

Then have a watch . . .

More Googleized recon seems to suggest the most flexible system is a Full Spectrum conversion and use of IR cut filters.

Have a look at this . . .

Most of these infrared shots were taking with a full spectrum converted Olympus E-410. A full spectrum (FS) camera can see in the Ultraviolet, Visible and Infrared spectrum with the appropriate cut off filter on the lens. For example if you have FS camera then you can use filters normally used for B&W photography such as yellow, orange and red filters for color infrared photography.

Okay, here's the full spectrum image . . .

. . . post-processed in Photoshop CC and with a bit of tidying in LR5.6 . . .

Good piece on full spectrum converted DSLR . . .

M...if I had the 7100 I may have a think about having it converted. I do have the 7K though and

am having think's...serious ones too, about the conversion. With hat said I still like shooting DX

in normal...ie...visible light spectrum! Perhaps it come down to a coin toss. The reason I'm

serious about the old FZ20 being converted is because of the lens & it's aperture of 2.8 all

the way from wide to tele...even if the digital zoom is used. And it may be a cheaper convert

also just in case I get bored with it. Gotta think of the possibilities...both positive & negative matey!

Fallen at the first hurdle. Protech Repairs don't convert Pentax. Just waiting on the other firm now.
