Just jumped in the ocean of infrared with a nex7 converted 715nm.
Tamron 28mm f2.8 not a winner here.
Canon 24mm f2.8 hmmmmm... better but...
Samyang 14mm f2.8............. BoooooYarrrrrr!
Second shot and gots me craving the daytime!!

Awesome! Infrared can be such fun, not so much trying to find lenses that work with IR though!

You have the filter in front of the sensor instead of in front of the lens?
(I guess that, because it's hard to use a filter on lenses like Samyang 14mm)

I have a full range modified NEX-5N. Using an UV/IR-Cut filter you can use it like a normal camera

UV/IR-Cut filter, Rodenstock Trinar 75/4.5 enlarger lens on bellows
DSC00016

+Schott UG1 + UV led torch
Silver Orchid UV

It also drastically improves low light performance so I used it a lot filterless for festival/party photography. A candle becomes a torch light etc.. Depending on light source, it doesn't even look very unnatural

Olympus Zuiko 3.5.28 and 2.8/35 both work well for IR as does the plain old CZJ Tessar 2.8/50.

Most lenses work reasonably well for infra red, under the right conditions.
Hot spots are the only real problem, and they depend heavily on lighting & aperture.

With adapted lenses it's often possible to fit the filter in the adapter, but it can affect the focus. (I'm still experimenting)

I ve been thinking of modifying my Nikon D50 to IR for some time as is mostly "collecting dust", but the cost is a bit high and no easy DIY solutions.

Haven't used infrared since digital came around but most of my MF Nikon lenses have a small red dot on the focus scale. You would focus through the viewfinder then move the focus point to the red dot for infrared. Because of this and the fact that the focus point needs to be manually readjusted, I would think that the MF lenses would be the best choice.

No need to convert a D50, all the Nikon 6mp DSLRs work fine for IR unmodified, you just have to use a tripod and a long exposure of a few seconds.

All my native AF lenses focus fine on my 'full spectrum' converted camera, no adjustment required - even with severe IR filters fitted. It's one of the benefits of mirrorless for IR another is being able see to frame/focus IR with no visible light getting through the lens, as the EVF shows what the sensor sees whatever wavelength.

The same is true with non-converted mirrorless models but nailing the focusing could be a problem (the noise in the viewfinder goes through the roof) - most subjects are probably too dark for AF if the cameras not modified. Older lenses with an IR mark certainly do help considerably if the cameras not converted. I did get reasonable results with a kit zoom (no IR mark) when I first tried IR with a standard G1 & more recently with the G5 when I wanted a long exposure.:

Yes i know that service and was thinking of giving it a try, but so far i was put off by the warnings. Re-thinking everything, it s probably doable otherwise why would they show the tutorial a all?

Yes Ian i know that, it s just that carriying a tripod around it s not my style of photography.

I very rarely carry one either, but sometimes a table top tripod, or just a folded jacket can work wonders Smile

I have to admit that having a converted camera does make IR a lot more appealing. I brought a pre-converted camera, which worked out cheaper than modifying my backup DSLR

I bought a Panasonic gf1 for cheap (£50) so i could try their tutorial, worked out and was easy to follow.
I might eventually get a sony nex to have another go.
I do like not having a tripod, just point, take the shot and go.

I have a converted Canon G3 that has "only" a 4 MPix sensor but which is good enough for my IR shots.

IR needs sun and clouds to really impress - an leaves or other green plants. Wink

I've converted a few mirrorless cameras to IR. I think I will convert more!!! Wink
One thing about NEX (NEX-3, NEX-5)... Unlike Panasonic where it's easy to remove the IR blocking filter, it's glued in those NEX, so I wasn't game to try to crack the glue. I think micro 4/3 or the Canon M are better for conversion.

Yes, I have noticed that in a number of very nice IR shots I have seen.

Wow !!! That image really seems to have a magical 3-D effect. (It must have a lot of pixie dust.) ( Smile )

Did you decide you wanted the ability to have false colour images before you had the camera converted? I keep pondering a conversion but I can't decide if I will end up just sticking to mono, and therefore getting the 830nm conversion...

Wanted to do both false color and black&white. Smile
