As above - after pressing the rewind button which dis-engages the film advance - allowing the film to be re-wound. Once re-wound, opening the back (by pulling up the rewind knob) will re-engage the film advance and 'drop' the rewind button for the next film.

The K1 looks about as good as it could, both aesthetically and in its list of features. If it proves reliable, it should be a winner. Its Achilles' heel, surely, is the paucity of matched lenses (I would be pleasantly surprised if many of the legacy lenses quite cut the mustard). Sony was in a similar - though not identical - position on the launch of the A7 a few years back (unlike Pentax, it was able to accommodate other makes' lenses via adapters), but has made considerable efforts to remedy the deficiencies in its own lens line-up. Provided Pentax lenses come through at better speed than has been managed in recent history, all should be well.
Sony had problems with light leaks between their own lens mount and their own lenses. Using lenses from other systems just adds variables (most definitely 'un-matched') to the equation and bulk to the outfit. Why buy a compact-ish mirrorless camera then stick a random DSLR lens on it with a clunky adapter (losing automation along the way)?

A lot of Canon 5D MKII/III users seem happy to use M42 SMC-Takumars on their cameras - gushing about how great they are and how they paid more for a 40yr old SMC-Tak 85/1.8 than a new EF 85/1.8 would cost. The only negatives are that performance at infinity drops off a bit (due to their crappy adapters not allowing infinity focus).

At least with F, FA & D-FA lenses the mount, the electronics and the AF are all matched. The camera knows the focal length, max. aperture, can focus the lens and for some lenses (apparently for 14 out of production lenses?) has correction profiles built-in. Many of these lenses are reported to perform well on other FF bodies, they will therefore perform at least as good and probably better on their native mount.

The K-1 is going to be a really important camera - it has the right mix of innovation, durability, performance, spec & price to really shake things up. As Pentax users we're quite used to (even bored by) SR on every lens you stick on the front - this is the first FF DSLR with SR - never mind the AA simulator, Super-Res & Astrotracer (not long ago Astrotracer cost £200 on its own).

which cameras where the K series lenses made for?
Erm, the K series (KX, KM, K2 & K1000) starting circa 1975, regarded by some to be the best manual focus K lenses (no 'A' setting). Slightly larger than the later M series lenses but very well made.

My main interest in the Pentax K-1 would be how the camera performs in northern lights photography and also landscape, thus the wide angle lens choices are important. Besides the very expensive D-FA 15-30/2.8, what wide angle options are there for Pentax fullframe? Well, there is the Samyang 14/2.8, the A20/2.8, the FA20/2.8 and FA*24/2.0 and also the FA20-35/2.8 zoom.
The FA20-35 is f/4 not f/2.8 - for me this is a better range than 15-30. How well the 20, 24 & 20-35 perform will be interesting. I chose the 20-35 over the FA20 & FA24 as I couldn't decide which focal length to go for (they were both expensive and hard to find and I couldn't justify them both). 20mm is plenty wide enough for me. I do have a K 17mm Fish Eye and have tested the DA10-17 FE on film - it seems OK @17mm (not sure which apertures though).

For me, size/weight are less important (I also us a P67) - you can usually leave something out of the bag (battery grip, filters you won't use etc.) to reduce weight. As I wear glasses, a high finder magnification causes me problems seeing the corners of the frame.

Over the last year or so I've been building a collection of FA lenses, I want the K-1 to get my focal lengths back and to get shallower DoF but will be keeping the K-5, LX and P67s.

For Sale: a Centon (Jessops brand) KA 18-28 f/4-4.5 (boxed).

This is a film era KA lens which originally came with a Ricoh pin (since removed by taking the mount off). Nothing like a good performer, it's saved so some extent because the ultra-wideangle (for film) focal length creates it's own perspective distortions unless you're careful).

Mostly metal construction, very good cosmetically, slight dust, no fungus, caps both ends.

I wouldn't recommend using it on a DSLR, but it offers a cheap UWA lens for a film camera.

£25 with UK postage, payment by cleared cheque, Paypal with fees or Bank Transfer.

Adding:

Pentax A-3000 body: Believed to work. This is the US version of the A-3 which is a program only body with a built in winder using 2x AA batteries.

Hi All,

Time for a clear out of various film bits & pieces, some of it probably works some doesn't. Over time I may add more, if you fancy anything please send me a PM:

Program A: body: (for parts) - shutter is jammed, no front grip, no pressure plate and no battery cover.

Jessops 'MEII' winder clone: believed to work (this also has an electronic release & crude intervalometer). Should fit ME Super, MEF, Super-A*, Program-A*, P50* (possibly others). * requires the front grip to be removed.

Pentax F70-210 f/4-5.6: non-SMC with focus problems - about halfway through the focus range it stalls the AF screw-drive motor, manual focus works but is quite rough - I don't recommend using this in AF!

Pentax MX winder: - Battery compartment screw broken, handle wobbles a bit (obviously been opened up before), foam holding the batteries in place has gone gooey - believed to work if the battery compartment cover is taped up.

Pentax SFX body: (for parts) - shutter Jammed, mirror won't drop, no battery holder, no film back, no remote release cover.

Pentax SFX ever-ready case: - complete but obvious signs of wear.

Prinxflex 80-200 f/4.5-5.6 - No 'A' setting, no fungus, some dust/minor marks but a metal one touch zoom.

The Tamron SP90 was always considered a great lens. I have quite a few K and FA primes but my favourite is the FA43 (on film only). The focal length is perfect for the 135 format - one lens I could shoot forever (if I could find a reasonably priced L-special I'd buy a Leica M6 for it).

A very close second (again for film) is the FA20-35/4, however being a zoom it feels like a compromise.

John.
