Olympus makes its own 40.5mm filters (or it used to) and theyre very high quality.

Great review Popo, and some nice test pics :wink: Although one of my first observations of the camera, is that it dosen't have an built-in flash, has this been annoying at all for you so far?

The kit zoom lens uses 40.5mm filters. I believe the kit pancake is 37mm.

The (lack of) flash hasn't been a major issue for me. I tend to shoot available light anyway although sometimes fill would be nice to have if there's a particularly bright background.

Looking back at the thread, I noticed I may have misread a previous question on focus speed. I meant that normal AF has the up to 1 second seek. In MF (prefocused) the lag is much shorter although I can't say how much right now.

Popo... this an IR I did awhile back with the B+W 40.5mm IR filter (similar to R72) at iso 80 on the C7070... do you think this kind of result can be duplicated with the E-P1 or E520/620?

2 second exposure at iso 80 at f/2.8 at 27mm (35mm equiv.)

I don't have anything exact to compare with, but the E-P1 might be a bit less sensitive to IR than that by a stop or two. With a little photoshop I think you can get something like that but maybe not exactly those colours. Erm... let me go through the few test shots I have and see if I can come up with anything close.

Thanks man. Did you ever try out IR with a e/410/420/510/520 or e620? Did you find the E-P1 about as sensitive as those dslr?

I think I did white balance off a grey card for that shot (actually I dont remember lol.) It was either a grey card or the foliage. And then channel mixer and autolevels.

Just standard AWB, remove colour cast in photoshop, channel swap, more colour correction, desaturate yellows to get rid of lens hotspot, and a whole lot of noise reduction.

I use photoshop elements 7. In menus: enhance>adjust colour>remove colour cast. Point on something you want to look white (might take more than one click to find a good spot) and ok.

For selective colour adjust: enhance>adjust colour>adjust hue/saturation. Rather than adjusting the master control, you can select individual groups of colours. In this case it wasn't use for artistic reasons, but to remove a huge yellow blob in the middle from the lens hotspot. You can see the middle region is still a different colour from the rest.

I need to use lower ISO and tripod I think. Or finish modifying the Canon, but that's another story. And I need to read the manual on custom white balance. Done it on Canon with good effect before, but I don't get the Oly menu system. It is by far the worst of the cameras I've used.

Thanks for the tip! Is that how you do all your color correction for IR? Yeah, I think the Oly menu system is on the complex side too, things you need are buried under submenued and things you dont want to change are right on top lol.

I make it up as I go along on each one. The colours are quite unpredictable at times so they all get PP differently. But colour cast adjust and red/blue channel swap are the basics to get the typical "blue sky, light leaves" look.

Erm... no idea. There isn't any dedicated socket for that function, so unless it can be done via USB for example I don't know... some day I'll read the manual and see what other features there might be I haven't used yet!
