Question about Tamron AF 75-300mm F/4-5.6 LD Lens?

Hi

I'm a newbie when its comes to different lens and am looking for a cheap affordable long range lens with auto focus, I've been looking at the Tamron AF 75-300mm F/4-5.6 LD and wondered would this lens work with the K-X and other Pentax DSLR's with auto focus, This is the lens on ebay

Thanks! that's good to know I've seen another Tamron AF 75-300mm F/4-5.6 LD lens but with the Di, what does this mean and is there be much difference using both of these lens on a DSLR? Tamron AF 70-300mm F4-5.6 Di LD Macro 1:2 Pentax: Amazon.co.uk: Electronics

I think that's just a more recent, digital-only version of the lens. Shouldn't be much practical difference

If you go to Tamron's site, it should explain the abbreviations they use. Each manufafturer has their own. But AF means autofocus pretty universally.

And another small point is that the 75-300 LD is just a shade under 1:4 macro magnification while the 70-300 Di is 1:2.

I attached some samples from the 70-300 LD 1:2 macro, not the Di version. I bought this lens for my film 8 years ago, still work well on a K-r. Sharp enough and nice bokeh for the price. Good travel lens, compact enough and more importantly, is cheap for beginner before moving on to the extreme lenses.

Thanks chongmic, the zooms seems good from your images, I've ordered the old LD lens with macro 1:3.9, I know that isn't great but I don't plan using the lens for close up of flowers or bugs. My budget was tight and it seemed like a good choice for my first for my first 70-300m lens.

I managed to buy this lens but it didn't come with a lens cap , can anyone provide me a link to a good place to buy a cheap lens cap for the this lens, unsure what size i will need to get the right fit.

Assuming you're referring to the Tamron Mdl 672D, any 62mm squeeze or screw-on cap will fit. Readily available on the internet or in camera stores.

The listed lens hood is Tamron 2B4FH but many other hoods for 62mm filter Tamron lenses will also fit.

I've had results equal to the Sigma and Tamron 70~300 Di lenses with this version.
