I was wondering if it is safe to use modern DA lenses on early K mount 35mm bodies such as the ME, MX, P30 etc?

I appreciate that some may not be fully compatible especially if they lack an aperture ring, some may not fill the frame, but would there be any fitting or electrical issues as to regards, for instance, their electrical contacts or other couplings? And would they safely function the same way as, say, a T2 mount mirror lens with a fixed aperture?

Thanks,

John

I know the issue first hand and research led me to these two videos on Youtube. So have a look at these. They relate to a K-x but the same issue seems to apply:

Try using new lithiums to initially resolve the power issue and suggest Eneloops to replace your current rechargeables (it could be that one or two of the rechargeables has gone bad.)

Are you using the latest firmware, v1.02?

Guess I could email [email protected] and ask about collecting in person from the shop. It's easily in range from my present abode.
Be interesting to see what the reply would be.

(I used to live near there!)

Apparently an International Calls Centre so unlikely a home address.

The Technical Contact shown appears to be in Vilnius, Lithuania. Isn't that where a lot of the eBay scams originate?

For the record I purchased my Sigma 10-20mm from Martins Camera Shop and had good service from them. They don't normally stock Pentax but got it in for me at a good price compared to elsewhere at the time.

Never heard of Yorkshire Cameras before.

Maybe worth trying resetting the Custom Function menu to the defaults (page 180 of the camera manual.) One of the settings turns off automatic focussing during a shutter press.

John

It's intriguing for sure!

Perhaps it could be a rangefinder that fits in the hot shoe and couples with the cameras electronics to completely bypass the front focussing issue: A traditional solution to a modern problem.

Received my £120 cashback from Pentax on Jan 27th so it took exactly four weeks to come through. If Pentax read the forum, then many thanks to you. Around a month looks to be normal.

According to the EXIF data #4 has an exposure bias of +2.70 EV whereas in #3 it hasn't. It seems this has been accidentally changed between shots.

Don't think I'd wish to trade with that seller somehow!

Personally I've had some great deals off eBay but one has to watch that there aren't any good deals in the shops (like the 100mm macro DFA) where 2nd hand eBay purchases can cost more.

Regarding postage costs, the only way to offset eBay & PayPal charges is to add a percentage to the postal costs or selling cheap items can end up costing the seller more than it does the purchaser. OK if you are the buyer but not good if you are selling! For PayPal I add 20p plus 3.4% to the postage cost then another 10% in respect of eBay's fees. Also set a starting price you are happy with unless you take a gamble on a cheap price attracting bidders.
