Infra red converted E-450

I am selling the E-450 I converted to infra red. I am open to offers but as a guide, a professionally converted E-420 sold on eBay recently for 335.

The camera has a 780nm filter fitted in place of the standard IR-blocking filter. The 780nm filter is a compromise between the more common 720nm filter, and the 830nm filter. The 720nm type usually lets through a small amount of deep red and can be used to obtain vivid false-colour images. The 830nm type lets through zero visible light but gives very good results in black and white. I went with Schott RG780 glass. This give images that can be processed to extract false-colour images of subtle tone, but is probably better for producing pure black and white pictures. For more information please see Jens Birch's article over on the USA site: http://forum.fourthirdsphoto.com/showthread.php?t=29059

The AF sensor has been fitted with a small piece of Lee Filters #87 which makes it focus accurately in the IR wavelengths. I have used it with lenses such as the 12-60, 9-18, 40-150, 25mm pancake and even the 8mm fisheye, all of which work well. You do notice some deterioration in lens performance, such as loss of sharpness at the edge of images using wide-angle lenses, but this is to be expected when you are using a lens designed for visible wavelengths.

Metering is best done in live-view, although it is also possible to meter visually and apply a correction using exposure compensation.

Please see my examples gallery: http://alistairj.smugmug.com/Photogr...15644323_xEFGx

In the box you get the E-450 body with the following bits: 1GByte XDcard, Olympus body cap, strap, eye cup, eyepiece cover, original battery, charger and UK mains lead, USB lead, manual, CD-rom etc.

Unfortunately there are a few permanent spots on the sensor. These show up at f/22 down to f/11 but are pretty much invisible below this. But note that diffraction sets in earlier at the longer IR wavelengths so you are unlikely to want to shoot with apertures smaller than f/8 anyway. Here is a shot taken at f/22:

Re: Infra red converted E-450

Accessing the service menu, the camera shows only 1305 shutter releases (to date).

As far as I am able to tell, the camera is working perfectly and should continue to give years of reliable service.

I'd rather see this go to a member of the E-system user group than have to put it on eBay!

Re: Infra red converted E-450

I should explain that I always intended to convert two cameras, one to sell and one to keep. I finally got round to converting a second body, which is an E-420. So the E-450 is now for sale.

Re: Infra red converted E-450

I have now accepted an offer on this, so unless there is some unforseen problem with payment or delivery, the camera is now sold.

Re: Infra red converted E-450

No problems with the delivery, so I imagine none with the payment either!

A pleasant deal has been done with Alistair - recommended.
