Changing to a Sigma 24-70mm f2.8 HSM (and clearing out a load of stuff) so this will have to go.
Its been a great lens, bought 'used' from WEX earlier in the year. I have mainly being using it at work for Portrait/VIP walk around but want something with silent focus and a tad wider.
Its in great condition, comes with the original Hood, and front/rear lens caps.
Looking for £155/Offers inc UK Postage.

Some more photos, its really in as new condition, apart from the two small knicks on the hood.

As part of my lens collection downsize, I am offering my FA*24 up for sale. I am looking to downsize my stuff and get a zoom to cover the individual primes. Probably going for a 24-70mm f2.8 (Sigma HSM or new Pentax D-FA).

Its pretty much mint, just a tiny nick on the top/front of the lens hood. Other than that the lens itself is as good as new.
Its nice and sharp in the centre wide open, and works as it should, as you would expect.

It comes with the original Hood, and original front/rear lens caps. Unfortunately I don't have the original box.

I will post some more photos up later.

I am looking for £315 inc UK Postage.

If someone wanted the FA*24 and the FA135 I'm selling, I'm sure I could do a deal together.

The Sigma Foveon cameras have RGB photosites for each pixel (on the 4.6mp and 15mp cameras anyway) so they only take a single image, hence you don't 'need' a tripod to use them.

Both the Pentax 'Pixel Shift' and Olympus 'High Res/Sensor Shift' are different. They only output the interpolated image into a Jpeg file.

The Pentax uses the SR to take 4 separate images and merge them together to sample the Red, Green and Blue pixel information and merge them together to create a 24mp image with pixel level detail and RGB values.

The Olympus uses the Image Stabilisation to take 8 photos, and merge those images together to create a ~40mp image from the 16mp image sensor.

The Sigma cameras (SD9-SD1M and DP1-DP1 Merrill) cameras have a layered sensor that has a Red, Green and Blue sensor for each individual pixel, so taking 3 colour readings for each pixel, and no Bayer Interpolation. You only get a single image, in both the 3XF RAW file format and Jpeg if you so wish.

The newer Sigma cameras, with the Quattro sensor are slightly different.

I have had both the Sigma DP1X with the 4.6mp Foveon Sensor, the Sigma DP3M with the 15mp Foveon Sensor and a K-3II with the Pixel Shift.

I think for pixel level sharpness and RGB colour information, the Sigma Foveon is still the best approach, as you only take a single image so no issues with multiple exposures. I have yet to find a situation to use the K-3II Pixel Shift, other than Product Photography, even then you only get it on Jpeg output, rather than a single RAW image.
