EX2F - Capable little Infrared tool - even HANDHELD!
Nov 2, 2013
For grins I got one of the EX1 extension tube for the EX2F. You have to add another 58mm ring (58mm UV minus the glass) on the end or the EX2F lens can hit an attached filter. Still there is no detectable vignetting even at 24mm.
Next I figured I would try throwing an R72 IR filter on there to see how the EX2F deals with it. If you've never seen one it basically looks like a piece of black glass on the front of the camera. The results are much better than expected!
1. The most important part is that the EX2F is IR sensitive enough to make shots possible even handheld with the OIS!
2. The EX2F autofocus works beautifully except in very low light even with the R72 filter on there. It had no trouble locking quickly in decent outdoor lighting. Thanks no doubt to that bright little F1.4 lens.
3. The EX2F display is certainly dimmer and basically purple or red (depending on the WB you set) but quite usable for framing again due to the bright lens.
4. Finally, when properly processed, the EX2F RAW files have a fairly film-like grain so even shooting at ISO400 can get some nice grainy IR shots. If you want low grain, then 80 or 100 are probably required.
The EX2F basically meets all the requirements for an unmodified IR capable camera! As usual, a tripod is really best for IR (with OIS OFF) but I am pleased with the handheld results.
Below is just a test shot at ISO100. Needless to say this was converted from RAW in Lightroom. You won't get any useful IR work out of the Samsung JPEG engine (which is rather bad IMO).
Like most cameras the AE system in the EX2F can be fooled by having an R72 on the front. It will produce what looks like a decent histogram but actually clips the RED channel with enough light present. You need to dial in about a stop of negative exposure compensation to keep that from happening. Of course that will vary with lighting conditions.
Anyhow, for all it's little quirks it turns out to have yet another use! I really like this buggy little camera.
Here is the test shot. This was ISO100, f2.0 (to sharpen the corners a bit) with OIS on. Not bad at all for a handheld shot! Download the full size to see what the grain looks like.
Yeah, I blocked out the shadows over there on the right but this was just a quick test edit. There is actually detail there in the RAW.
