On the problem of Sony micro-single NEX-5TY dual lens: E PZ 16-50mm F3.5-5.6 OSS and E 55-2 10mm F4.5-6.3 OSS.

E = Sony micro single system bayonet. Dedicated to Nex system, APSC camera

PZ= electric lens. When preparing for home shooting, the manual zoom ring is omitted, and DC pulls up the lever for zooming.

16-50mm= focal length, and X 1.5 is needed to calculate the equivalent viewing angle, because the APSC is smaller than the standard 135. The equivalent viewing angle of this lens is 24-75 mm Basically, it is considered that all lenses within the equivalent 40mm are wide-angle and those above the equivalent 75 are telephoto.

F3.5-5.6= aperture, the smaller the number, the larger the aperture. 3.5 is the aperture at the end of 16mm, and 5.6 is the aperture at the end of 50mm. So this head is a dog's head, not a constant.

The optical image is stable.

So the latter is easy to explain.

E system, anti-shake telephoto lens, focal length 55-2 10mm, aperture 4.5-6.3, only manual zoom is supported.

If you still don't understand this, search for the most basic knowledge yourself. Google can find all these things.
