K-X buying a lens

Hello,

i recently bought the k-x with the simple stock lens.

After a holiday trip i am thinking of buying an extra lens - a zoom one.

Could you please guide me on how should i select one, as i know that sometimes these can be very expensive and i don't want to spend so much.

Thanks

Hi there, I am a K-x owner as well.. I am currently owning the Pentax 18-55mm kit lens, Sigma 70-300mm APO and Tamron 28-75mm. Basically, the Tamron 28-75mm replaced the kit lens because of the similar range and produce heaps better pictures. The Sigma 70-300 is used for taking pictures of my dog and his mates, lots of close up shots and fast movement shots. I could be more helpful if you could tell us what you would like to take with your future new lens?

The ~$350 DA 55-300mm lens is great with the K-x. The high ISO performance of the K-x is so good that the DA 55-300/K-x will work well for indoor (like high school gyms, theaters, etc) as well as outdoor subjects.

The optically identical DAL 55-300mm costs about $100 less but isn't quite as well built & lacks the instant manual focus feature.

Both lenses are lightweight and yield superb image quality.

I bought a DA L 55-300 for about $230 on eBay. I don't think the plastic mount is that big of a deal, and I don't miss the quick shift because I've never had a lens that has it. Now that I have it I wish I'd bought it as part of the kit.

See the many, many, many other threads here on in the Beginner's forum comparing the basic telephoto zoom options: DA50-200, DA55-300, Tamron and Sigma 70-300. Also see the lens review section of this site. Bottom line: 55-300 is universally considered best, but also a bit more expensive than the rest. The others all have their plusses and minusses, which have already been described in detail in the existing discussions.

BTW, note you already *have* a zoom lens - the 18-55. The word you are looking for is "telephoto".

Maybe there could be some sort of sticky for the DA 50-200 v. DA 55-300 v. Tamron 70-300 V. Sigma 70-300

I'm relatively new here but maybe just a sticky with a bank of threads discussing those lenses. I think it's almost inevitable to ask when choosing a first telephoto for the Pentax Mount

I would go for the Pentax 17-70/4.0. Good range, good image quality, good autofocus, good macro. It is a great step up from the kit zoom, and having a constant aperture (that's what the 4.0 means) makes a huge difference.

Here's a link to a great review: http://www.photozone.de/pentax/408-pentax_1770_4

Basically i am lost i don't know what to get as a starter lens! I went into the marketplace, but there are so many!!!

I am not a professional and will use it on occasions as mentioned above - not quite often - and on travelling.

What would you recommend? I suppose it would be better to buy a used one right?

Thanks

Welcome to the party.

I don't shoot zoom lenses, but it sounds like you may be a candidate for a zoom with the widest range there is at good quality. Like the Tamron 28-300 quoted above.

If you have to go wider, you can put your 18-55 kit on there.

You need to better understand/explain why the lens you already have is insufficient for street photography or kids. For wildlife, it's pretty obvious that longer focal lengths are useful, but not so much the other subjects.

A great walkabout lens is the 40mm Limited pencake lens or the 21mm Limited if you want a wider angle. Used with the Kx, the light weight and small size makes a great combo for travelling, especially if you need to carry the camera for long period of time.
