A note about shipping fees during the Corona shutdown: I usually offer a shipping rate of only 15 USD for fully-insured Air Mail shipment to all countries of the world. Unfortunately, due to the Corona crisis, commodity traffic has been greatly reduced. To some countries, commodity shipments are no longer available for the time being. To still other countries, like the United States, only Premium Parcels are being offered. International Premium Parcels are fully insured and will be delivered on the fastest track available now. The shipment fee for an International Premium Parcel will be 59 USD. I have entered this as the default international shipping rate. If a cheaper shipping rate is available to your country, you will be charged accordingly and get an immediate refund through PayPal. If shipments to your country are presently unavailable, I'll cancel your order with your permission and send you an immediate refund of your total payment through PayPal. I'm sorry for this inconvenience and thank you for your understanding.

You are buying a high-quality telephoto lens, with only 65mm length perhaps the smallest 135mm lens ever built. It will give you all the benefits of sharpness and color transmission (Super-Multicoating, SMC) a manual prime lens can offer you over an autofocus zoom lens.
In addition, the Pentax lens offered here has the following benefits:

(1) only 65 mm long for a focal length of 135mm;
(2) super-multicoating of all glass elements;
(3) solid full metal barrel;
(4) eight aperture blades for pinpoint sharpness;
(5) smallest aperture stop 1/32 for increased depth of field (especially in close-up photography);
(6) telescoping lens shade (you'll never forget you sun shade).

SMC PENTAX-M 1:3.5 / 135mm Serial Number 6334820

Condition of the lens: L
ens is in full working order, very few signs of use to the barrel (please see photos). Engraved numbers and letters are clear. Glass is clear and without scratches or fog. The aperture ring is moving freely and well defined, with no oil on the blades. The focusing helicoid is moving easily, allowing for precise focussing. Comes with Pentax front cap and OEM rear cap.

A note about dust:

Dust is everywhere in the environment, unless one lives in outer space. Occasionally new participants to photography believe that dust in a lens is a fault and question about it. It is impossible to find a used lens without dust, and even new lenses have some dust. Dust is out of the photographic plane and simply will not affect a photograph. The only dust that will affect a photograph is that on a DSLR camera?s sensor which is in the photographic plane. Indeed, there will be some naturally occuring dust floating in the space between the lens and your camera?s sensor and this will not affect a photograph as it is 'averaged out'. Dust is only a cosmetic issue and does not affect photographs. For this reason, I do not mention internal dust in a lens unless there is a lot of it, or if there is a large particle. Should I find fungus, I will get the lens professionally cleaned before offering it for sale. The same with stuck apertures or stiff focusing helicoids -- I simply will not sell them, unless I'll make full mention of it. Promised.

 
Conditions of sale: I'm a professional photohistorian, testing the lenses I'm selling before I offer them on the web. I'm selling these lenses at moderate prices and inexpensive shipping rates to all parts of the world. Please understand that I do NOT offer returns or refunds. All lenses are accurately described and pictured in close-up shots. These are vintage lenses in used condition, offering image qualities that you will not get with modern digital lenses in plastic barrels, BUT these lenses are not coming straight from the factory. Neglectable internal dust or neglectable cleaning marks are to be expected and are not defects. If I detect internal fungus, a stuck aperture or slow focusing helicoid, I will get them cleaned before selling. I'm judging the lenses I'm offering according to their image quality. I'm not subjecting these lenses to unnatural conditions in order to discover faults. Thank you for your understanding!
