Left it a bit late to take photos of the lenses so here's the other stuff for now, I'll take shots of the lens optics in the morning and upload them.

I'm selling the following:

Schneider-Kreuznach D-Xenon (Samsung) 12-24 F4 ED AL, basically it's the DA12-24mm.

Lens is in excellent condition, no internal dust/scratches, some slight wear to name on lens cap, it's stored that way, and a few light cosmetic scuffs on lens hood. Supplied with original caps and hood. Unfortunately no box so priced at a bargain price of £395 including RMSD, IMHO definitely the best UWA for Pentax cameras.

Pentax SMC F-50mm F1.7 (autofocus) optics are excellent, no dust/scratches, some slight cosmetic marks on lens casing, hardly noticeable. Supplied with a metal screw-in lens hood (non pentax), lens caps. Unfortunately no box so priced accordingly at £175 including RMSD

Pentax AF-360FGZ flash, excellent condition in original box/pouch .. £105 including RMSD


Only selling these as I'm buying a Nikon D800 and keeping the K5 just for travel.. photos to follow shortly, any questions please ask.

Just to put a Pentax-specific practical slant to this, here is my method for eyeballing focus accurately. This is most useful perhaps for wider angles and tripod work, and in lighting conditions when it is hard to see your focus point clearly through the viewfinder.

Firstly I frame up the scene using through the viewfinder and get the composition set. I mostly use my 14mm or 28mm primes, so its manual focus, which I find best for this type of photography anyway. Set an appropriate aperture for a maximum DOF using hyperfocal-type technique (depends on the distances in the scene).

You can get the focus near enough through the viewfinder, but for fine tuning I press LV (Live View), then the Info button - this zooms in 6x, and using the 4-way controller I move the little green square down to an object that is about 1/3rd into the scene, an approximate hyperfocal distance. Then I fine tune the manual focus, back and forth until I see its as sharp as possible.

Leave it there, press LV to come out of Live View, and you're ready to shoot!
Works just as well with auto focus, I do pretty much the same but switch to Live View and choose the selective focus point I think is closest to the Hyperfocal distance, in fact to be safe ever so slightly past it, then switch over to manual.

Another "rough & ready" technique for Hyperfocal distance is to decide the detail nearest to you that needs to be sharp, chose an object double it's distance away and then focus there

Have a look at the new version of the Sigma 17-70, gets excellent reviews which suggest it outperforms the DA18-135 and the DA17-70 which I use and find excellent too

I use a Benro Travel Angel 2...this is the aluminium version but I actually have the CF one bought directly from China via Ebay at an excellent price, anyway it's a great sturdy tripod http://www.parkcameras.com/23904/Benro-Travel-Angel-2-Aluminium---B1-Head.html?r...

Also have a look at these, very highly thought of.. http://www.3leggedthing.com/ website is a bit geeky for my taste but products are excellent

To be fair Redsnapper are also very good for the price

If you have an android mobile have a look at the DOF CALC app, I use it all the time

It depends when you want to take the photos too..in the low light at evening/sunrise a 3 or 4 stop is very useful but in bright daylight the 10stop comes into it's own, a 3 or 4 stop would still struggle to produce the effects I guess you're aiming for

I've read the 645D vs D800 comparison and it's pretty impressive results from a FF camera, already mentioned before that FF is on the horizon for me and the D800 is so far the one I'll be going for.

I'll wait a little longer to see if Pentax stops messing around and makes their FF strategy clear but I still have concerns that it will be an untested body and lens lineup against what's now a well tried, tested and highly praised camera, I think Pentax pricing could be tricky too, if indeed they do even produce a FF
