Looking for a new zoom lens for my K-X & am confused

Hi

I recently broke (accidentally) my husbands Sigma 100-300mm lens that fits on his k-x. I am after a new lens & dont want to pay a fortune when I can find brands besides Pentax or Sigma that fit. Im sure it will be cheaper to buy another lens than get it repaired so I am turning to the forum to ask advice from all the camera gurus out there!!!

Also, when we would zoom in with the Sigma, it would become very light so the pics looked over-exposed. Im not sure if that was a lens fault or how its supposed to be.

We are new to photography with this type of camera (interchangeable lens).

I have heard that Sears, Tamron, Quantaray, Tokina and other brands will fit BUT this whole K mount thing confuses me as I look at the mounts & think they all look the same so Im not sure if the Sears ones I am looking at on ebay wil fit

I have also bought a m42 to k mount so I can look for other lenses (hasnt yet arrived....only just got it on ebay)

I love taking photos & want to find a nice cheapish lightweight (compact!!! Well, as light & as compact as the Sigma was, its still smaller than many of the other zooms I have seen on the market) lens than can take good photos from a decent distance. And, what helps take good night shots??????

All help appreciated. My camera advisor friend died last year so I am glad I have found this site for advice

Thanks all!

All these third party lenses will work with Pentax: Third-Party Lenses for Pentax - Pentax Third-Party Lens Review Database

I would recommend the Pentax 55-300mm, which should be roughly equivalent to your old lens: SMC Pentax-DA 55-300mm F4-5.8 ED Reviews - Pentax Lens Reviews & Pentax Lens Database

If needed, you can get a used "DA L" variant which is the same lens with a plastic mount and no quick-shift manual focus for under $200.

It's not completely clear if you understand that some of these lenses are AF and some are not. If so, then I apologize for pointing out the obvious. But of the lenses you mention, only relatively recent lenses from Pentax, Tamron, or Sigma will be AF. No lenses from anyone else are likely to be AF (maybe an occasional Tokina), nor are any older lenses and and certainly no m42 lenses.

As for exposure changing as you zoom in, no, that should be the case, unless you using spot metering for some reason. that mode shouldn't be used unless you know exactly what you are doing and have a specific need for it. But it's also the case that cameras generally try to render everything as "average" brightness. So very light-colored objects will tend to look underexposed, and very dark-colored objects will tend to look overexposed.

Check out the lens reviews in the lens review database here on the Forums.

Pentax Reviews - Pentax Lens Reviews & Pentax Lens Database

At this link are Pentax brand lenses, and at the top, you can select 3rd party lenses for other brands. If you want something used, you have a lot of options. If you want something inexpensive and new, Sigma and Tamron both make 70-300mm zooms under $200.

For good night shots, you'll probably want a tripod. Or maybe you'll want a fast prime lens. It really depends on what you specifically want to do.

Errr, hang on, are we talking the Sigma 100-300mm f/4 EX???? Because that Sigma is an exceptional lens with a $1,000 price tag. To not get it fixed and instead replace it with any of the junk lenses you list would seem a crime.

Are you sure you dont mean you broke a Sigma 70-300, which really is a cheap lens that is not worth fixing and could be replaced with something like a Pentax DA 55-300.

Here's what a 100-300 looks like

twitch is right, if it is the sigma 100-300mm f4, i think it deserve to be fixed instead of getting something inferior.

yes, you better get a new one. You will often see Tamron 70-300 Di or DA(L) 55-30 in market place to replace the broken one.

No it is not worth fixing that lens, better off getting a new replacement

No. It has to be for Pentax. All autofocus lenses for Pentax will work on the K-x.
