In England during the Winter, I favour my Tamron SP 70-200 f2.8 instead of the 70-300, as it gives better IQ, but it's too heavy to take abroad.

Yes it appears that infinity focus is adjusted from the front.
Thanks for the link, I did read that PentaxForums thread already, but it didn't make any sense to me. I can't see how re-fitting the helicoid on a different 'tooth' would make any difference to infinity focus. You shouldn't have to remove the helicoid at all. I think I'll just take it apart and see for myself how it adjusts.
Kind Regards

Hope you are well, my thoughts are that you should look for a good Sigma 17-70 f2.8-4 lens. These can be bought at good prices and they are a versatile and reliable tool. However, if you do this, make sure it's one of the later lenses from the 'contemporary' series, these have two advantages over the older lenses. 1) they are much lighter and 2) they are far sharper at all focal lengths. The older ones can be a little soft, I know this as I've had two of the older ones and currently own the contemporary version, which beats the older lenses into a cocked hat.
Hope this helps.
Kind Regards

This is a long shot, I've already asked the question on the Pentaxians facebook group to no avail, but I'm hoping someone on here has the knowledge.
I have a HD DA 70mm f2.4 Limited lens which takes beautiful images, but the infinity focus setting on it is incorrect and so it will not focus to infinity on my K-1 nor on my K-3ii. I am experienced in adjusting infinity focus on older Pentax primes from the K and M series, this is an easy job once you've taken the name ring off the lens. However, I don't know whether the infinity adjustment on the DA 70 Limited is made via screws accessed from the front of the lens, or by removing the rear mount. I would rather know this before I start taking it apart and wondered whether anyone on here knows the answer. Once the adjustment screws are accessed it should be an easy task to make the adjustment.
I'm hoping it's accessible from the front, as the removal of this is very easy!
Kind Regards
David

Well done on fixing your camera, it's the right thing to do rather than junking it or selling it as not working. It might interest those who wish to repair their solenoids on a K70, K50, K30 etc. that the white solenoids don't have to be bought on ebay as a single item, you can buy old camera bodies and remove them. The Pentax digital bodies up to and including the K-x all have them, as do the older film bodies such as the MZ-M, MZ-S and other cameras in the same series. You can pick up these old film bodies in a non-working condition on ebay for between £5 and £15.
Once you have the solenoid, if you're OK at soldering it's a pretty simple job to do the fix.
Kind Regards
