Bear in mind that there is a crop factor when using film lenses on a DSLR (due to the size of the sensor). Generally you should multiply the lens by around 1.5 to find the 35mm equivalent - the 50mm becomes a 75mm on digital for example, and the 28mm a 42mm.

The 135mm is a bit long therefore for portrait work. I plan to use it for motorsport and anything involving distant subjects in low light, such as concerts.

I would second the suggestion of the Pentax-A 50mm f1.7. Also worth a look at the slightly more expensive 28mm f2.8 from the same series. Both are nicely compact on a DSLR.

The Pentax-M 135mm f3.5 is worth having as it's faster and more compact than zooms in the same focal range. Same probably goes for the 200mm F4 - I would like one of those but have yet to find one in good condition.

I didn't know that different paper sizes were available for the Selphy, that's definitely a plus point for it.

All I can say about that review is that nothing pleases everyone. It isn't a top-quality photo printer, that's why it costs around £20 for the starter kit. I've not noticed fine lines on mine, and providing that the source file has decent contrast it seems to produce reasonable results.

It isn't intended for "serious photo journalists" (something I have no desire to be - as the initial post has it, lighten up and shoot!), it's supposed to be fun, like the old Polaroid instant cameras. If I want to print something to hang on the wall I'll use the IP90 and some good quality paper.

Ah, ok! I thought that most were chrome and the black versions were more unusual, as per the K and M series. Oh well, I'll still have an interesting old SLR to tinker with!

The nicks in the front element may not make much difference. I have a 28mm with a few scuffs/scrapes to the coating on the front element that still seems to perform well. It may object to certain lighting conditions, but I've not noticed any flare or similar problems yet. Given that it cost about a third of the price of a mint example I'm happy. Just wish I could find an original Pentax front cap for it at a sane price - I'm not paying the £7 asked by one infamous ebay shop, given that I found one for £2 a month ago!

However, if the seller failed to mention these faults when you bought the lens I really feel you should ask for a refund. My 28mm was sold with a full and frank list of its flaws, which is how it should be.

My Mother also owns a Selphy (the one I've had a brief play with), I'm not sure which model but it can definitely take a rechargeable battery as she ordered a couple of 3rd party ones. They seem to work ok, although she did say something about having to trim a bit of plastic to make them fit properly.

The Selphy paper has two perforated strips. Once these are torn off, the photos are postcard sized (and the paper has pre-printed markings on the back to allow you to use it as a postcard).

Well, I made an offer on it yesterday and had it accepted today...

Not as bad as the MX with a 50mm f1.7 lens that I saw in a feeding frenzy. It hit £103 with over an hour left. The MX is probably one of the best Pentax have ever made, but that's still silly money for a camera that isn't particularly rare and is over twenty years old.

I caved in and ordered a brand new Industar 50mm pancake a week or so ago (£16 including postage) so I'll use that to test the camera and buy a 55mm f1.8 Takumar when I know it can be trusted. I don't own any other M42 kit, but I know the black versions of most Pentax SLRs are more desirable so thought it worth a go, as it looked in decent condition apart from the battery cover.

I'll agree that they're small, but to be honest I find the Selphy photos a bit undersized too. There's a certain charm to these little sticker prints too - they remind me of the pictures you see pilots wedging in their control panels in films.

The A4 ones from my IP90 are a good size for displaying at home but obviously the IP90 is a bit too bulky to carry around.

Well, I've had my PoGo for about 13 hours now, printed around 20 shots, and I love it. It does have limitations, it works best on photos with plenty of contrast but if the photo looks good on the LCD then it'll probably come out well on the PoGo. I can also print from my Eee PC with a Bluetooth dongle.

Only snag is that the power input is a proprietary design with a roughly rectangular two-pin plug, rather than a barrel connector. This might pose a problem for anyone attempting to run one from a solar phone charger.

I would say to anyone who's interested, buy one. They're not expensive, work with Pictbridge, and produce surprisingly good results.

I've just snagged an ESII on ebay, it looks ok but is minus the battery cover. I should be able to fix that by making a part, but I need to know what sort of batteries I should use? I know some of the pre-K series SLRs can be a bit picky about what batteries they'll work properly with.

Assuming I can get it behaving reliably I plan to reunite it with an SMC Takumar 55mm f1.8, as according to the manual this was one of the choices of kit lens.
