Schwer begeistert
Habe mich für diese Lautsprecher entschieden um meine alten, passiven und klobigen DJ-Monitore für zu Hause abzulösen.Mir war vor allem wichtig, ein aktives und möglichst kompaktes Lautsprechersystem zu bekommen, ohne dabei mehr als 100€ zu investieren. Das die 3,5“ Lautsprecher nicht so druckvoll und voluminös klingen würden wie meine alten 5“ habe ich dabei bewusst in Kauf genommen.Um so verwunderter war ich, als ich die Speaker zum ersten Mal in Betrieb genommen habe. Voller, satter und vor allem linearer Sound, den man bei solch lütten Lautsprechern niemals erwarten würde. Keine kreischenden Höhen, keine Blechdosen-Mitten und auch keine Blubberbässe.Für den Preis wirklich unschlagbar und absolut zu empfehlen.

Works just as it should. Need to be careful not to apply too much polarization. Some slight lack of uniformity of effect across entire filter. Entire filter can be moved to minimize lack of uniformity

Q
What adapter is needed to charge the battery set?
A
Simply connect any 5V 2.1A Max output power source via USB cable to safely charge the battery in the included charger. The connected power source can be a mobile phone adapter, car charger or mobile power supply, etc. But please do not directly connect the charger with a power supply higher than 5V 2.5A. 
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
does this fit pentax cameras?
A
Please verify your camera's lens thread size(usually marked somewhere on the lens barrel or printed underneath the lens cap) before ordering.The number is always preceded by a "ø" (diameter) symbol 
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).
