RE: Quick survey
I shoot DNG - never did a comparison so do not know which is better. Just assumed it is the same.

Re: Quick survey
I shoot DNG exclusively (though I usually run the files through DNG Converter when downloading because I can have it do file renaming at the same time and it gets me to the latest spec DNG) for 3 reasons, in increasing order of importance: 1 - Files are smaller than PEF 2 - The open format of DNG (it's based on TIFF) is better for future compatibility than almost anything else (except possibly TIFF itself and JPEG) 3 - The embedded MD-5 hash makes file validation possible en mass, that is to say, without opening files and looking at them. (This final item is largely why the Library of Congress adopted DNG as its archiving format.) -- Mark Roberts - Photography & Multimedia www.robertstech.com -- %(real_name)s Pentax-Discuss Mail List To unsubscribe send an email to pdml-le...@pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
back caps and body caps
I've found there to be a tremendous range in both quality and price of K-mount back caps for lenses. I have not found there to be consistent correlation between quality and price though. Some of them will tighten down nicely and stay attached, others will stay loose and just fall off. Has anybody found good deals on quality K-mount back caps?

Re: back caps and body caps
I've had good luck with caps by OP/TECH USA from Amazon. Over the years I've used both their singles and doubles. Never had one come loose or fall off. https://tinyurl.com/5n7y2xhm -p On 6/24/2024 12:15 PM, Larry Colen wrote: I've found there to be a tremendous range in both quality and price of K-mount back caps for lenses.

Re: back caps and body caps
Thanks, do they actually cover/protect the electrical contacts? On June 24, 2024 10:46:21 AM PDT, Paul Sorenson wrote: >I've had good luck with caps by OP/TECH USA from Amazon.

Re: back caps and body caps
Yes, they extend out to completely cover/protect the contacts. They also have a rubber O-ring that help with some friction to keep the cap from turning and keeps any dust from getting to be back of the lens. -p On 6/24/2024 12:53 PM, l...@red4est.com wrote: Thanks, do they actually cover/protect the electrical contacts?

Return of the prodigal K-3 III
My K-3 III was delivered today after being repaired by Precision. It took just over a month from my sending it in, they had to wait a couple of weeks for a replacement top plate. One might think that if service were their goal, they'd keep a better stock of spare parts on hand. sigh. It seems to work, as does the $75(with shipping)Tamron 18-250 I got to replace the broken Pentax 18-270, which I got to replace the broken 18-250. Sigh, I sent the original 18-250 off for repair just before I ended up getting my K-1, and only did a perfunctory test on it, and didn't notice that it no longer focused at full zoom. When I did eventually notice the problem, Tamron informed me that they no longer worked on that lens, and wouldn't even fix it, even if it was just a factory misadjustment. sigh. I'm going to need to go back and re-RTFM on the K-3III, they've changed so much in the UI since the K-1, I could barely find anything, like turning off the focus beep, or setting it to shoot in raw. For some reason the filesave type is showing as RAW+DNG In any case, it's nice to have it back. There are a lot of aspects of its UI that I've definitely been missing, both when using the K-1 and especially on the OM-5 -- Larry Colen l...@red4est.com sent from ret13est -- %(real_name)s Pentax-Discuss Mail List To unsubscribe send an email to pdml-le...@pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
