To be honest, I am a very amateur photographer and could really use a mentor to help lead me in the right direction as to what lenses are best to use. I guess I just got confused. I have two 1800 w soft boxes flanking the painting, so there is a lot of light.
Does the flaring have anything to do with the K01 being mirorless? Again, I basically know nothing about photography, I just use this camera for photographing my work.
Thanks.

I tried it. It didn't work. Thank you.

Do you think a flashlight would illuminate the whole painting or just a certain spot? What I could really use is a large lamp that can illuminate the whole painting and something I wouldn't need to hold. Any recommendations for something like that? I recently bought two halogen light bulbs to point at the paintings as I've read halogen puts out more IR than other light sources.

Again, I'm new to photography and just don't know what I'm doing. I can easily return the lens. I only have this one camera to work with. I'm photographing paintings mostly at a distance of 5-15 feet for the whole painting and then of course I like to be able to zoom in for some macro shots. Sometimes i have a rather large painting, like 4ft x 4ft, and I'm just not able to get the whole painting in the shot. I'd rather not have to switch out 2-3 lenses during a photo shoot, but is that not possible? Especially since I have to attach filters to each lens and they might need step up/down rings and I'm not sure I could afford to buy so many.
My 50 mm takumar lens works okay but I think it doesn't produce the most crisp images. Perhaps because it is a vintage lens.

Hello,
I have a K-01 full spectrum converted camera. I had been using my 50mm 1.4 to shoot my IR subjects (paintings), but sometimes a painting is really large and the 50 mm can't shoot at the range needed. I just bought a Pentax DA 55-300 lens so that I could shoot at different distances. However, when I attach my IR filters, I can't seem to find my subject matter. It's all dark no matter if I adjust the lens. Both 850 and 950 nm show nothing. I tried my Schott UV-1 Bandpass filter and I'm able to see my subject but there is an odd flaring of light which can be seen in the attached photo that I can also see while I adjust the zoom with the other filters.
I guess I'm just hoping that I'm not doing something right and that this lens will work with my filters. Anyone have any pointers?

I will mostly be taking photographs from a distance of about 1-10 ft., depending how large the painting is, so perhaps I could look into a macro lens for those close ups. Thanks for your input!

I will look into the DA 35 mm, also suggested by another user. You are correct, I have yet to fully investigate what type of lighting I will need and I will purchase some protective eye gear. I have a lot of research to do! Thanks for giving me some great ideas.

Thank you for the info on the DA 35 mm. It is a lot out of my price range at the moment, but I will keep searching for a good deal. Thanks for the tip about not shooting towards the sun.

Hello,
I am a paintings conservator from Columbus, Ohio. I have just purchased a full spectrum converted K-01. I intend to use the camera for painting analysis in the infrared and UV spectrum. I am hoping that this will help my painting restoration business grow. However, I am new to photography, and really need some help and mentors.
I purchased the camera from a seller on Ebay, body only. I have purchased two different lenses so far--the DA 40mm pancake lens and a vintage SMC Asahi Takumar 1:1.4/50mm.
For the Takumar 50mm I have purchased an IR/UV cut filter, and 850 and 950 nm IR filters
I just purchased 720, 760, and 850 IR filters and IR/UV cut filter for the 40mm (27mm), but have not received them.
My main concern has most to do with which lens is preferred for infrared photography? I will mostly be using it to photograph paintings at a close distance, not landscapes. Something else I'm not totally clear on is if I need to place a visible/UV spectrum blocking filter if I'm shooting in IR....if that is even a thing. Also, setting a custom white balance for shooting in IR with my K-01. There are many more questions, but I shall start with these.
A friend who is a photographer will be giving me a basic photography lesson discussing f stops, iso, wb, etc....
I don't have a lot of money to spend. I am self-employed and have been spending a lot of money on this venture already, so vintage lenses are best.
I appreciate any advice and recommendations!
Thank you
