Disassemble a DAL 18-55

(in Chinese, English Translation Here (machine-translated).)

The lens is fully dissected and the functions of different parts of the lens are explained. Really interesting.. Btw, it can also be seen how the design of the DAL is "simplified", just say, even now infinity focus collimation is not possible with this lens, but just it was checked and fixed at the factory, one-off and "discretely".

Thanks, Rice. Very interestiong. Even though simplified, this lens is still very complicated. So, it is great that these kit lenses are made available or affordable, enabling more people to enjoy photography. I would never have bought Pentax based on its current prices for its metal mount lenses.

So it means that DAL lenses are "simplified" in more ways than previously thought. I wonder does this "simplification" affect only lenses marked as DAL, or all lenses with the plastic bayonet (i.e. DA 32mm f/2.4 as well)?

I believe the DA35/2.4 is a true DAL lens in principle, i.e., a crippled design from an existing lens/optical formula, plastic mount, no quick-shift focus, no focus scale, no lens hood bundled and so on..

DA35mm f2.4 is technically L (light) high quality non-all metal mount & body, but not designated as such because of its high quality image making. This is very logical, not to create a delusion of a cheap lens or perception of (optically) substandard lens. Just an affordable HQ fixed FL, which it deserves.
