A Must Have for any toddler
The images, artwork, sound design, easy to press buttons were great and engaging.Only issue is the binding is weak and easy for a toddler to tear while turning the page.One of the reasons I'm buying my second copy.

STOP LOOKING!! You have found it!!!
If you are looking for a great circular polarizer for a great price then you have found it !!!!! like i have said before in another review get a rocket blower blow off the dust then use a liquid cleaner like purosol lens cleaner make sure its real clean then put it on and enjoy ... for the money you can not beat it i do not regret getting this once again tiffen had made another bang for your buck filter.. so go on ahead and click the buy button

Simply the Best..nuff said
I guess it knocked down the other competitions in the arena of bluetooth headphones simply because it's the lightest the easiest and the longest time to use

Fantastic and comfortable headphones
Excellent on ear headphones, very comfortable with a lot of volume to spare. I use it mainly to watch movies and they are perfect for that use. The music, dialogues and the effects are perfectly separated without being annoying. The EQs of these Marshall’s are thoughtfully crafted. With a battery that last forever, I’m extremely happy with my purchase. I had some Bose before and found them lacking in volume, not a problem for these Marshall’s.

Q
is this EF to RF adapter and suitble to canon eos r100
A
yes 
Q
How much does the adapter weigh?
A
About 300g,0.66 Ibs. 
Q
Will this adapter work with the canon eos-r?
A
no it will not the eos-r has a different mount 
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
Is the K&F Concept adapter for Pentax PK K mount to Sony NEX e-mount compatible with the Sony A6000? Does a P-KA mount adapter exist?
A
Yes it should work with the sony a6000. As long as the ka lens has an aperture ring on the lens and is not solely dependent on receiving aperture control from the body, this adapter should work fine with ka lenses. To my knowledge, there are no sony e mount to k mount adapters with electronic coupling so no lens control through the body (meaning aperture and focus are fully manual).
