Body of Pentax lenses for digital ME

Boa noite.
Tenho uma velha Asahi Pentax ME e pretendo comprar um corpo digital, aproveitando as lentes da Asahi Pentax ME.
- SMC PENTAX-M 1:1.7 50 mm 2619017 ASAHI OPT. CO., JAPAN
- SMC PENTAX-M 1:2 35 mm 6042468 ASAHI OPT. CO., JAPAN
- SMC PENTAX-M 1:3.5 135 mm 6707385 ASAHI OPT. CO., JAPAN
- TOKINA SZ-X 1:3.5-5.3 28-200 mm diam.72 8815477

Quero saber se a pentax K5 é aconselhável

Obrigado

Yes, these can all be used no problem. See this article:

They will work, as noted with manual metering, and some histogram checking.

But Pentax-A lenses are much easier to use on the Pentax DSLRs. That's because you get full metering with them. This is reflected in the much higher price that the Pentax-A 35/2.0 commands on the used market compared to the Pentax-M version. (The Pentax-A 50/1.7 is very common and cheap.)

You may find that you need a third-party focusing screen to be able to manually focus accurately on any DSLR (not just Pentax).

Also, remember all these lenses get a 1.5X crop factor on Pentax DSLR.
