A great buy for anyone!
I couldn't be happier with this pack. I was able to fit both my Canon and my Pentax cameras in the bag with 7 lenses, cleaning supplies, a 10-inch tablet, extra batteries and a rain cover for my cameras. My laptop fits perfectly as well as my tripod. I even had room for snacks and a water bottle for those long days hiking or working the scenes as a photojournalist. Definitely a great buy for anyone.

Great originally, even better with ribcage
Really solid for the price. Check out the Ribcage mod to use c-mount lenses with it

Good Deal
For the price, it can't be beat. If you're using it for something heavy, you'd probably want to spend more. I'm using it for a Pentax DSLR camera. I'm not using lenses that are too big. I did some night shots of the sky/forest and they turned out great.

Perfecto para Canon
La anilla es de aluminio, pesa poco, quedó perfecta en mi cámara Canon T6 y no hace juego con la cámara; además viene con rosca a M42 lo que da una ventaja puesto que algunas lentes Barlow u oculares vienen con ese hilo (M42); por lo que solo se monta la cámara con la barlow u ocular y entra directo al enfocador del telescopio. También el mismos enfocador de mi telescopio tiene el hilo M42 por lo que puedo montar la cámara directo a foco primario. También tomen en cuenta que puede que necesiten un adaptador de M42 a 1.25 pulgadas, ya que este producto no lo incluye. Realmente es muy útil, solo recuerden que deben buscar la anilla T para su cámara; es decir, para su marca y algunas veces modelo de cámara. Esta anilla no le queda a Nikon, Sony, etc.

Q
Will this allow my nikon 1 s1 lenses to mount to my canon t2i?
A
Dear Customer, so sorry to tell you that this adapter won't allow your nikon 1 s1 lenses to mount to my canon t2i. 
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
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. 
Q
Will this adapter allow me to mount a fujinon m42 55mm 1.8 and a sigma-z m42 135mm 2.8 to a sony a6000?
A
HI your fujinon m42 55mm 1.8 and a sigma-z m42 135mm 2.8 are M42 mount, the item can fit your camera and lens
