What is it for

jaccy60 · 12-01-2012, 05:15 AM

Hi, so glad to find this forum. Have been reading through some of the posts and I am well immpressed with the site.
I was having a mouch through some stuff in my loft when I came across a rather large lens. Takumar 1:4/300 complete with hood, tripod mount and brown leather case that is felt lined. I haven't got a clue what it's for, can anyone help please

I assume the camera end has a 42mm threaded fitting. The lens can be used on any Pentax SLR or DSLR with the correct adapter.

This lens is described here: Takumar 300mm F4 (1962) Reviews - M42 Screwmount Telephoto Primes - Pentax Lens Reviews & Lens Database

That's the one, it has a silver end mount with a black and red dot on it

How do I tell which cemera it is for?

If it's an M42 lens, it's for any camera with an M42 threaded mount, or any camera that you can get an M42 adapter for (which is pretty much any camera - including Pentax DSLRs!)

It is a lens that I would never use as it is way too big, would it be worth selling it and what should I be looking for it, I can then put the proceeds towards a much needed flash.

The beauty of Pentaxing; any Pentax camera you like. If it's a DSLR or some 'newer' SLR K-mount, you'll need this or an eBay knock-off:
Pentax Mount Adapter K reviews - Pentax Camera Accessory Review Database
If the camera has threads on the lens mount, just attach the the lens.

When you open the link, you'll discover another hidden wonder of the site. Hundreds of reviews on all things Pentax. All the K-mount cameras reviewed need the adapter, the screw-mount or M42 mounts don't (many of the older film cameras). Here's your lens:
Takumar 300mm F4 (1962) Reviews - M42 Screwmount Telephoto Primes - Pentax Lens Reviews & Lens Database

Often, historic prices appear in the reviews but not this time. Do an eBay search but don't get carried away by the BS there - too much stuff hyped-up

Oddly enough, you may just want it. I have just bought an older manual focus 300mm f1:5.6 - the faster f1:4 would have been nice.

You shouldn't have much trouble selling it here or on eBay if you price it and describe it correctly. Look at some adverts on here to see what people want to see and read about the glass and the aperture blades.

Or you can just send it to me, I'll take care of the minor details...

Deffo won't be using it myself, it will be up for sale.

That sounds like it already has a K-mount adapter on it. All the Pentax M42 screw mount lenses I've ever seen were pure black and had no red dot.

Does it appear to be a large diameter (42mm) screw thread, or a "bayonet" mount that turns about 1/8 turn and locks on? That lens is definitely from the screw mount era. If it appears to be a bayonet mount, then it almost surely has an adapter on it, or someone has done major surgery to it. If it is an adapter, it should unscrew, although it may take some effort if its been on there for years.

If you could post a picture of the lens mount end, we could tell for sure.
