Commenting on a few posts here:
1) Primes have had their day, unless you have a massive user base, you won't sell enough to warrant their development. Some shooters prefer them, but the proportion who are able & dedicated enough to spend £3-500 each on several prime lenses instead of buying an 'industry standard' popular zoom is very low.

2) Don't stress about the lens range. There's enough for everybody (although I'd prefer constant aperture f/4 zooms instead of 3.5-5.6). I see no need for a lens wider than 20mm (except fish-eyes), super wide-angle zooms or ultra-fast wide angle primes the size of a P6x7 lens.

3) What did I spend the money on instead:
Fixing my LX and obtaining some K series lenses for it.
Adding lenses to my P6x7 outfit.
Shooting more film.
Buying a GR.

I don't understand K-1 prices, they're all over the place*. The K-1ii is less than the K-1 was last month, the K-1 Special Edition & grip was/is cheaper than a standard black one and separate grip. The prices seem to have been ping-ponging between 1.5 & 2K (25% difference). The dealers always claim they never make anything on cameras, so it must be Ricoh/Pentax changing the pricing. I was thinking about buying one, but won't be now, the cash has gone on P6x7 lenses instead.

* unless I've missed a cracking deal somewhere that lasted for more than 5 minutes.

The weight difference is rarely significant, it's more the reduction of lens choice and practicality of longer lenses. There are few zooms, those that are available are very expensive (there are no independent options). An xx-300 zoom for FF is relatively small and reasonably affordable, for a 645Z the equivalent is something to 450mm or so - these are either un-obtainably expensive, and/or impractical to carry/use. If you're dedicated enough you can manage them - the P645 has/had one of the largest MF lens ranges available, all the way to a 5kg 600mm f/5.6.

I use MF film cameras, irrespective of format, the bags are similarly sized and similar weights, the difference is the number of lenses/accessories you can fit/carry. The Pentax 6x7 is thought of as a huge/heavy camera - in reality it's about the same size/weight as an FF DSLR with grip and f/2.8 standard zoom - the difference is you only get one focal length. Minimise your lens choice to one or two lenses and there's not much difference.

With 35mm I find I'm carrying everything all at once (just because it happened to be in the bag at the time), even if I don't have any use for it, it gets carried. With MF, if you take out the lenses, filters, hood etc you don't need, it needn't be bigger/heavier than a 'fully loaded' DSLR bag - but you lose some flexibility with lens choice if you need more than two or three focal lengths.

Yashica built a left-handed version of their Samurai (half-frame integrated film SLR): link

The Ricoh XR-X had the option of setting the self-timer to zero seconds, the self-timer button was on the left side of the camera.

35mm (film): FA20-35/4 - perfect focal length range, fast enough and works with all my film cameras.

6x7 (film): SMC 6x7 45/4 - perfect wide-angle focal length, quite compact and balances well on the camera.

APSC (K5): FA28/2.8 - approximates to the 43/1.9 field of view, for some reason I can't work out, I prefer this to the FA20-35/4.

Traditionally very few Medium Format cameras had independent lenses made for them. There are so many formats, many with leaf shutters in the lenses, that the market is generally too small for independents to design & manufacture lenses. Its not like you cantata a generic lens computation and stick a different mount on it like you can in 35mm.

The few non-manufacturer branded lenses available in MF are largely joint-efforts with the camera manufacturer.

Diopter correction lenses sold.

The MX winder also includes the instruction manual.

Hi graevy, Sorry missed that I meant to put it at £25 posted to the UK.
