Fantastic Value
Fantastic value for the money. I got two, deeply discounted at around $10 each, and am still wondering whether the low price was a mistake. These would be worth it even at regular price. Very sturdy!I attached one to a Pentax K3 with no issues. The other went on my vintage Pentax 35mm, and for that I needed to use a standard hole punch to make the small hole in the little protective leather flaps just a tad wider. On both cameras, the straps hang just right.I am a short woman, and the length is just fine for me with no adjustments. I can either place it over one shoulder, cross-body, or around my neck. The reverse side is a soft suede-like fabric. I especially like how the part right where it hits my shoulder has extra padding.The color is a beautiful cognac brown and looks amazing. (My picture has pretty dark lighting.)I will report back if anything changes, but so far, so good!

It's about the only small "smart" flash for the Ri
I have a new Ricoh GR III. This is the only small, system-compatible flash that Pentax/Ricoh offers that works with the GR III. It's still too big to leave on the GR III all the time. But if you want a ceiling-bounce flash shot of a group in a dimly lit room, this saves the day. I love the GR III, but you simply can't ALWAYS rely on available light. So if you know when to use a flash and how the flash modes work AND you have a current Ricoh GR series camera, this is probably the flash to get. But I wish they made a smaller one yet...

These are good!
These keepers are good. Arrived in time, and fit really well around the lens barrels of a Pentax FA 35mm, DA 18-55mm and even the Tamron 70-300 Telmacro. Everything as described, hope the adhesive spot sticks well on the cap.

Nikon Keymission 360 BedVlog Review: which it were
Last week we received the Nikon KeyMission 360 [ #KeyMission360 ]. @NikonUSA.We are long time users of the great Ricoh #theta360 BUT have long hated and complained that it NEEDS to be 4K.Next week we should have a 360 and 2D actual REVIEW, but here is a quick test in our kitchen talking about biscuit basics and sex tapes in 360 degrees. Porn has a great future with these things.So, PLEASE LOOK NEXT WEEK FOR full review and PLEASE SUBSCRIBE.Here are some initial notes:- 4K resolution STILL only gives you a 480p or 720 video look, but it is MUCH much better than the 1080 of the Ricoh Theta S that ASPIRES to be 240p VHS quality- The Ricoh Theta is MUCH, MUCH more ergonomic. I have it slipped into my pocket at ALL times. And the best camera is the one that you have on you.- The Nikon KeyMission 360 can NOT fit easily in any pants pocket AND has two big buttons that i fear will take a LOT of accidental videos and photos. I wish there were a way to LOCK the unit- i wish the unit came with a protected hard shell case with microfiber walls and maybe a lanyard so i could cary it around. I don’t know where to put it and how to avoid pushing the buttons that both turn it on and start recording- unlike the Theta 360 which is SUPER easy to put in pocket and hold and manage, it’s VERY hard to hold and manage the unit without touching the two giant lenses- as with all 360 cameras, sometimes you see the seems and sometimes you don’t- as with all 360 cameras it is VERY unclear how to EDIT and then upload footage and still have it be 360 degree viewable. Final Cut [and other editors] strip the metadata. For this upload i used the free “Spatial Media Metadata Injector” app. This is the same app I use with the Ricoh Theta S after editing and before uploading. It seems to work for YOUTUBE iOS app and Firefox on Mac, but Google Chrome is NOT seeing the video as 360… i am not sure why- it is GREAT that the video comes out of the camera pre-stitched in “equirectangular” format. With the Ricoh Theta S you have to use the free “RICOH THETA” app to re-encode.- on the Mac [or PC] to preview the video you use the KeyMission 360/170 Utility. It doesn’t do much, but it does let you VIEW [and spin around] the videos. Unfortunately once i edit in Final Cut and export i CANNOT open these files in this app- As with the Ricoh Theta S the critical thing to know when EDITING in Final Cut or any editor is to create a CUSTOM SIZE Project. 4K video is 3840 by 2160 BUT once 4k video is changed to “equirectangular” format it is 3840 by 1920. So you MUST have a CUSTOM SIZED Project or Sequence in your editor to match that. Then also after you edit you have to RE-inject the 360 degree metadata that was stripped with a utility like “Spatial Media Metadata Injector”- Final Cut X 10.3 complaint: WHY, oh WHY does the brand new Final Cut X NOT have 360 degree video features for preserving 360 degree metadata AND including the features of the $119 Dashwood 360VR Express and the free Dashwood 360VR Viewer. 360 degree video has arrived… why is it such a pain to deal with?===- the flattened live capture option is based on WINDOW size…. it should export framing changed at MAXIMUM resolution from the source [like a 1080p flat video]- Mac Safari and Chrome still won’t play my video in 360- Double the bitrate of Gear 360 after stitching [30 vs 60-70 mb/s]- in camera stitching- overheating [30 min?]? record time?- See our 360 degree video review on YouTube iamnotapoet channelPlease note: you MAY need to watch this on an iPhone with YouTube app or Firefox for the Mac….

Q
I need a dn filter and i have a 70-200mm nikon fx lens, does it work for me? thank you for your answer
A
I use one on a Pentax 24-70mm filter size 82mm. Just make sure you buy the right size for your lens. I have the nd1000, and I am very happy with result. They also sell adaptor step down for your other lens. 
Q
Will this work with the pentax mount asahi takumar smc 50mm 1.4?
A
Yes. I have the same lens and adaptor on my Sony a7ll and it works beautifully. The m42 is also known as the 'universal' mount as other 3rd party camera and lenses also used it. I own 6 other K&F e-mount adaptors to different lens makers (ltm, MD, CF/CD, Nikon) and they all are well built with a nice snug fit. Highly recommended. 
Q
Will this work on my sony a6000 and tokina minolta 100-300mm macro zoom?
A
Yes 
Q
Which M42 adapter should be used on your lens?
A

Please note: our M42 adapter ring could not be suitable for Pentax Takumar Super Takumar Carl Zeiss M42 series(aperture pin does not fully depress, small tabs sticking out), as ours depresses the aperture pin all the way down

 
Q
Pentax pk mount usually means pentax k mount which has a flange distance greater than m. is this adapter for adapting leica m lens to pentax q camera?
A
I actually have not received this adapter yet. It's shipping from China. Don't think that was disclosed in the ad. However, I do not believe this is for the Pentax Q body rather for digital and film cameras that take the Pentax K mount in its many variations. So I'm expecting to be able to mount my Leica M mount lenses on my digital and film Pentax K mount cameras, no autofocus or relay of exposure information, only to be used with manual focus and exposure.
