Pentax Resale Value Guides

6 guides to what used Pentax is worth — the price at each condition grade, which lines hold their value, and how to date or identify what you have. Pentax is the last maker still committed to optical-viewfinder DSLRs, which gives it a loyal following. Its old film bodies and the M-series lenses are collected in their own right.

Which Pentax pieces hold their value

The K-mount lens system, which has stayed compatible since 1975 so old glass still fits current bodies
M-series and Limited primes, which are compact, well made and sought after
Film bodies such as the K1000 and MX, which are mechanical, repairable and popular with students
Weather-sealed bodies and lenses, which are a genuine differentiator and worth stating

And what pulls the price down

Fungus and haze in older lenses, which is permanent and spreads
Sticky aperture blades on old lenses, caused by lubricant migrating, which needs a strip-down
Dead light meters on film bodies, which are a specialist repair
Early digital bodies, where the sensor generation dates the files heavily

Identifying and dating yours

These are the checks that decide which end of the range a piece sits in, and they are the facts a serious buyer will ask for:

The serial is on the base plate of a body and the lens barrel near the mount
Say that the lens is K-mount and whether it fits current bodies, since the long-running mount is a real selling point
Hold any lens to a light and photograph through it to show the glass is clear

WishThrift does not authenticate or inspect anything. Condition and origin are described by the seller against five grades — what each one means — so photograph the markings above rather than asserting them.

Frequently asked questions

Is used Pentax worth buying?

It depends far more on the line than the label. Pentax is the last maker still committed to optical-viewfinder DSLRs, which gives it a loyal following. Its old film bodies and the M-series lenses are collected in their own right. Each guide below says which Pentax lines hold their value for that item and which have almost none, so you are comparing like for like rather than paying for the name alone.

How do I check a piece is genuine Pentax?

The serial is on the base plate of a body and the lens barrel near the mount. WishThrift does not authenticate, inspect or grade anything — condition and origin are described by the seller, so ask directly and expect an answer. A seller who has the item will send a photograph of the marking in minutes.
