We'd need legal opinion to explain it, but I suspect it may be something to do with the complex laws governing copyright across the world.

If a supplier like Google has to resize your image for transmission it's changing it, for example, so the licence is needed to allow them to. Can they show in in every country for you or are they "publishing" it and do they therefore need permission?

There could be so many perectly reasonable reasons for the wording as well as the ones that make people suspicious. Most contracts would scare you off totally if you read them carefully.

I've only just got it and haven't even had time for a proper try out yet, so it's not likely to be up for sale for a long time.

It's the most promising option I've found so far. Quite heavy, but not unreasonably so, fairly compact and respectable performance at f8.

However, this was only a quick first impression, so we'll see!

Many thanks, but now sorted out.

I'm delighted to hear it went well, sorry I couldn't be there.

Effectively it was for the Leica system. Very expensive and very poor.

The biggest problem I see is power supply. You could make a back for a LX or any other similar Pentax, but the cameras are getting old, it would need more power and the back would cost more than a new DSLR.

Just think if a digital back for the ME Super came out tomorrow at £500 how many people would now want it? Not enough I suspect. And when your ME Super wears out what do you do then?

It came to nothing, so presumably no investment available or insurmountable technical problems.

The FA 50mm f1.4 belongs to the earlier group and I suppose is the last of the original FA film lenses. It's optically the same as the M series lens as far as I know, so its pedigree is a long one.

The only note of caution I would sound is that I don't agree with the statement the film lenses that are equal in quality to digital lenses. - that's not really the point.

Lots of the later lenses are equal in quality to the earlier ones, despite being manufactured in a different way.

For the purposes of digital photography some (not all) film lenses will be less suitable, that's true, but it's not necessarily related to which group of film lenses they belong to.

I understand and empathise with your dilemma, but I'm a real hoarder so not the best person to offer advice on this!

There are many different types of FA lenses. Early ones had lots of metal construction under the plastic exterior and some of them can be quite heavy.

Later ones can be split into two types. The first type are "consumer" lenses such as many of the 28-80mm and 28-90mm ones and they are relatively light whether silver or black. It's still all plastic!

The "pro" lenses such as the Limited range are made of metal again and whether silver or black are still metal and rather heavier. But the colour doesn't affect things.

Hope that helps to clarify things!
