I did try them last year for some 35mm D&P but found they weren't as good as SnappySnaps so I haven't been back. Of course printing from digital is an entirely different kettle of fish so don't forget to report back on your findings

Quick update: Just added a Zeiss Sonnar 135mm in M42 mount to the above listings in case anyone's looking for one

I agree with this. My 12-24 is fantastic for interiors, architecture and (at the 24mm end) street shooting. For landscape work I prefer something longer to give a more natural perspective - I tended to use the FA43 for most (nearly all) my landscape shots but recently I've been using the DA35 with great success. I'd suggest your 28mm + 50mm lenses would probably fit the bill better than either the DA14 or Sigma 10-20.

So true!

It might be helpful to know which lenses you already own as you want to avoid too many overlaps if possible. All three of the lenses you have mentioned have their fans on here (along with the excellent Pentax DA12-24 f/4) so I'm sure many will be happy to give you their own personal opinions on which is best for you.

In my experience, yes.

For macro work using tubes and bellows I find the slower (f/2.8 - f/4) Tessar-type lenses work the best as they have fewer elements and a very flat plane of focus (in other words the corners, edges and centre all reach their optimum "sharpness" at around the same time, whereas something like an f/1.4 will get sharp in the centre quickly but it takes a much smaller aperture before the corners catch up). Having a flat field is a lot more noticeable in macro work than it is in general photography.

My personal favourites are all M42 lenses, however, if you want to stick with K-mount then the M50/2 is quite a nice compromise and very cheap! I just happen to have one on eBay at the moment (shameless plug): link

The Pentax K mount has a registration distance of 45.46mm. To retain infinity focus you need to use a lens with the same or greater distance. The Pentax 645 system has a registration distance of 70.87mm, so even if the lenses could be mounted inside the 645D's throat (which I doubt as lenses tend to be quite a bit wider than their mounts alone) that's still a loooooooong way back!

Nice idea Don but I think the laws of physics are against you on this one.

The same kit here would cost at least £150 more so I'd say that was a very good deal indeed

One more essential I'd add would be a spare battery, other than that you seem very well sorted.

Never mind Vic, if you don't ask you don't know

I just arrived there by a process of trial and error. I found the colours using that setting were pretty close to using regular daylight film, which was what I was after.

There's no wrong or right way, I just dislike the auto setting as it continually adjusts itself. I don't like the hues shifting from shot-to-shot just because I've happened to move from sunshine to shade (or whatever) - I prefer a consistent colour cast even if it's technically "wrong" sometimes.

The little Sun icon represents Daylight - usually the second option down after Auto.
