Technically, the 43mm was the first serious re-design of the standard lens for many years and took full advantage of all the progress in lens technology and design that was available.

However, the 50mm lenses were already superb lenses, so although in theory the 43mm might be a superior beast I'm not sure how much this would translate into a huge difference on a print, even a very large print.

Any 43mm users out there who can tell us differently?

It sure was an awesome range.

Some of the more exotic lenses are very difficult to find now. Others, although not exactly common, are available with a bit of patience. The 15mm f3.5 crops up quite often, for example.

Well, sort of anyway. The new AP (out today for subscibers, on sale on Tuesday) has an extensive and interesting test of the Tokina versions of these lenses.

They come out very well indeed, with outstanding optical properties such as high resolution, low vignetting, very well controlled distortion and an virtually perfect control of CA.

The relationship between these and the pentax lenses is noted, as is the price difference. Apparently the Pentax versions are both £100 less than the Tokina Nikon and Canon-fit versions.

It is also mentioned that the Pentax-Tokina collaboration extends to the 10-17mm and 12-24mm lenses, contadicitng earlier AP comments that involved Schneider. It's a complex world of lenses...

Do have a look at the test as it's full of good information.

Stereo photography has been around since the beginning. Pairs of images on card would be mounted in a viewer. In the 1960s/1970s GAF made a plastic viewer for images mounted on the rim of a circular card.

Proper 3D images can look stunning, and as stated, you don't need red/green glasses.

I'm sure it is.

Different suppliers change their portfolio of products all the time. Quite a few in the UK are now also embracing Samsung as well as Pentax, so market share will without doubt be increasing.

Thanks, very interesting.

You will get a far more varied response this way.

There is also a forum section here for photos.

Sorry, Tim, velocity is a vector quantity and you will need to specify a value and a direction.....

Unfortunately phpBB2 doesn't have the "geek" or "uber geek" smiley...roll on phpBB3....

A reapir house can replace the IR filter with plain glass. This is done quite a lot in the USA and Fujifilm actually market IR versions of their S5 Pro and S9600 cameras.

Minox actually make small deigital replicas of some classic cameras such as the Leica, Rolleiflex and Contax. They look pretty but are just about useless as cameras.

The Pentax 110 and 110 Super are gorgeous little things, the only pity about the system being the mass of different filter sizes and the actual 110 film cartridge itself.

The bag is based on the Speedbag, one of my favourite small bag designs compact and very fast in use.

If anyone has a Speedbag, Speedbag M or Joybag L then I'm looking for nice examples of those.
