Welcome

Tha FA 35/2 is a very good lens for mid range, if a tad expensive. If you're on a limited budget then the Sigma 24/2.8 is a very good lens, comes up regularly on Ebay in manual focus and can be had with the "A" setting on the aperture ring. There was also an AF version of the Sigma but they're much harder to come by. The FA 28/2.8 is another fine performer if you can find one on the s/h market, it's optically different from the F 28/2.8 and possibly the best 28mm f/2.8 Pentax made. The older K 28/3.5 is generally regarded as very good also.

Regards,

John

I found some others on the Net, but may look at the OP/TECH Pro Digital Camera Soft Neck Strap or the Lowepro Transporter Digital or Film S.L.R Camera Strap. The Lowepro Transporter looks like it has a pouch which may take either a remote or memory card.

Any thoughts on these two anyone?
AFAIK the Lowepro straps all have pouches for memory cards, mine came with one.

I wouldn't mind the updates so much if they got them fully sorted before release. In the last 12 months I've lost all Internet connectivity twice due to MS incompetence. First time with Zone Alarm and on the last set of updates with AVG anti-virus link scanner. It's difficult to sort out when you don't have an internet conection

Register distance of the K-Mount is 45,46mm and the 645 is 70,87mm.
I don't know the depth of the lens cap so can't say how long the tube must be but the whole adapter must be around the 25,41mm.

If you make it longer you lose infinite focus.
If it's possible to assemle it non-permanent, so to speak, I'd start long and shave it a liitle at a time, you can always take some off, but........................

I recall reading that some of the DA lenses are full frame, the 40mm is obviously one but I can't remember the others.
DA*200/2.8 and possibly DA 70 Ltd.

I've got a great location lined up for some test shots, but can't use it until Wednesday pm. Be gentle with me here, I'm no fan of Ken Rockwell, but...................I find this really interesting

I may have a 645 rear cap somewhere, there's one on my 75mm lens but I need that, I seem to remember there being a spare somewhere, one of them "that'll come in handy someday"

I can supply the K mount from a Pentax lens (free) if you ever get around to making the adapter.
