Lens choice?

Hi everyone,

Sorry for another lens question but who better to ask than the people on this forum With foreplay out of the way, here's my question.

I currently have a K10D setup with a 2x TC and a pentax 18-55 kit lens. I want a bit more range so here are my choices. either buy a pentax 50-200 which is 52mm, works with the TC and any other filters i have and i can get it here in japan for about $220 USD. the other choice is the sigma 28-300 Hyperzoom which i can get for about $195 USD but obviously isn't compatible with the TC and filters.

Any thoughts would be most appreciated.

Cheers

Have you considered the FA J 75-300? They're only about 15,000 yen.

Or some other good alternatives

The Tamron 70-300 LD Di Macro is very good value and sharp and with the TC provides a pretty decent reach. The Sigma 17-70 is a good value replacement for the kit lens. Together these two provide a very useful travel set.

I would avoid superzooms. They are all soft for much of their range, lack contrast and exhibit high distortion. Dont waste your money on a good camera and buy second rate glass, its a false economy.

Actually, my first recommendation would have been a vintage prime, but I sort of assumed that like most people these days he would prefer a zoom.

rubbish.. focal lengh for focal they cant compare with a prime but they are not aywhere near as bad as u make them out to be..

but having said that i would favour your tamron 70 x 300 and sigma 17 x 70 choice.. but having tried the sigma 28 x 300 i can say it works quite well as a single lens walk about.. more so on a pentax body with SR..

i have some sample images taken with one for reference..

trog

the 28 x 300 and the kit lens would certainly be a cheaper solution for reasonable range

Let me second that point about the quality of the so-called hyperzooms. I have a Sigma 28-300, and I am quite happy with it. I can post a few examples if anyone is curious. Such a lens won't replace a good prime for portraits. But as a walk-around lens, the convenience is remarkable, and the sharpness is quite acceptable -- if you use it carefully.

Why shoot carefully?

First, the Sigma is heavy. It doubles the weight of the camera. This can make it tiring to carry and hard to use handheld.

Second, the lens is dark. At 80mm, it maximum aperture is 5.6. This is an outdoor lens only. A dark lens means that the *ist D autofocus will hunt around a lot.

Third, you need a steady hand or preferably a tripod for any shot with a focal lengths greater than about 120mm; otherwise, you will get consistently soft images due to camera shake. A good rule of thumb is that the necessary shutter speed for a shot is the reciprocal of the focal length. A shot that is framed with a 125mm focal length will require a shutter speed of 1/125.

If you can keep these caveats in mind, then I can recommend the Sigma 28-300. I don't reply on it exclusively, but I'm glad it is in my kit.

Figmental,

Lot of good replies already posted here and I don't really like to stir the pot further and confuse you but here goes.

First off, I think you have considered, first, what you want to shoot and where you are most likely to capture the subjects you want to get. That will narrow down the lenses you want to go after.

Personally, if you are on a very tight budget, the FAJ 75-300 will be a good choice if the subject is outdoors or under bright light/flash. Disadvantage is you've got a gaping hole from 55-75 unless you use your TC. This was something I missed in my lens collection. I hated it a ton and just recently filled the gap with my SMC-M 35-70. For this reason I would heavily consider the 50-200 or, if you need to go cheaper, the very underrated Sigma 55-200.

Sigma 55-200/4-5.6 DC

If you are looking used, going that route opens up a lot of options as some lenses can be acquired for as cheap as $40 USD plus shipping (or sometimes cheaper). I have a 3 used telephotos that I am testing for my camera. Eventually I will keep just one and sell/give away the others. All are great "outdoor" or bright light/flash required lenses.

P.S. This is your first post - welcome!

I have no experience with other barndīs superzooms, but I cannot recommend the SMC Pentax FA 28-200.... It is about the worst lens I have mounted on any of my film SLR cameras in terms of image quality (I cannot understand how this Tamron lens qualified to have the Pentax name on it)

As for telezooms, the 50-200 is a good buy and if you go Samsung, itīs almost a steal too. $143.00 here in Stockholm and I guess prices over your way is somewhat lower?

Pentax needed a Super Zoom to be competitive supposedly, but from what i have heard it was one of the better performers of its age, thanks to SMC etc.

thanks everyone, i really appreciate all your comments. I think i'll go with either the sigma 55-200 or the pentax 50-200. they're both fairly cheap and will do for me. actually, the sigma i can get here for about 13,000 yen...sweet.
