Lens decision: Pentax 16-45 and 50-200 combo OR 18-250?

I currently have the Pentax DA 16-45, which is my starter lens for my K10D. It's a nice lens but I want to get into the telephoto end of things with another lens.

So I'm debating whether to:
a) buy the DA 50-200 (it's $179 here in Canada) to go along with my DA 16-45

OR

b) go to the hassle of selling my DA 16-45 and buying a DA 18-250 (which can be had for $569) to cover wide angle and telephoto in one lens

Let me know your thoughts and opinions of either setup and which way you'd lean.

I have a FA 50mm 1.4 (great lens!!!) for alot of my indoor low light portrait shots, so poor light performance of the lenses won't play too much into my decision making process.

Thanks

tough call. you'll probably appreciate the extra stop of light at the long end if you were to go with the 50-200, but the appeal of the 18-250 is definately strong. If you find yourself missing a lot of shots because you're going from wide to tele alot then I'd get the 18-250; otherwise, stick with the 50-200.

We are sitting in the same situation and have opted to wait for the 18-250mm Pentax when it is available. Why? Convenience. We travel a lot and I don't want to carry several lenses. Plus as someone else mentioned, I don't want to lose a shot because of changing out my lens. That's my situation and it may not be yours.

I don't have any experience with the Tamron/Pentax 18-250, but I can't imagine it matches the image quality of the 16-45. While convenient, a 14x zoom undoubtedly compromises image quality compared to a (very very good) 3x zoom.

For all inclusive walk around lens for short buisness trips, I love the Tamrom 18-250 just so convienient as a travel companion. I have no complaints on quaility - however I am not a pixcel peeper. For me they quality is more than enough (I print so few and rarley over a 5x7). I find I use the low end much more than the wide end , but do use them both.

I take the 12-24 as well everyhting fits in a small bag (leave the battery grip off) . When I have my suitcase , Laptop, the less camera gear I have to carry the better. Computer & Camera are my carry ons. Now if I got a computer / camera bag I may change that procedure

On extended vacations I take 'em all (see sig).

It is indeed a hard choice - What do you need?

There is a lot of discussion on this question right now, and the answers are not easy to glean from all the excellent suggesions that come from the residents of this forum. In my opinion, it all boils down to what you need, which is based in the main on what you want the lens for, and what kind of photography you will be doing.

If you want several kinds of photography to be your choice, and want excellence in all of them, then several lenses, preferably single focal length of high quality, or short range zooms of high quality. Then you will have one for portraits, one for landscapes, one for groups, one for wild life etc etc.

If you want to travel, and space, weight etc is a worry then one very good lens with flexible range is perfect. The Pentax and Tamron 18-250 Super Zooms fit this category. Neither is likely as good as any of the special application lenses, but overall would be a good compromise.

For me I have 2 or 3 lenses that are special application lenses, and a Tamron 18-250 Super Zoom for everyday shooting. I would not take it into the city at night for shooting city lights, nor would I take it to a wedding as my only lens, but as an all round walk around lens for outdoors it is perfect for me.

The investment in a zoom lens is not a bad idea if you want to find out what you will need, I think better than purchasing a $1,000 FA 31mm lens which while it may be the best in it's class, is unsuitable for telephoto or wide angle usage, only to find out you will be doing mostly telephoto work.

Try the Pentax or Tamron 18-250 if you are unsure, and note your most common usage the buy the best for that type of shooting.

here are som links to pics taken with the Tamron 18-250 to give you some ideas on what it can do with a K10D.

Hope this helps a git.

I would go for option c) Buy the Tamron and keep the 16-45mm.

Since I've been working with the Tamron for the last 4 months, I can confirm the opinion that it is a great walkabout lens.
However, it does not match the quality of your 16-45. Therefore, keep it.
The 16-45mm does great indoors, in cities works better in low light.

You can always decide to sell it.
Do you have any idea for what percentage of the new value you can sell it?
If you don't, perhaps you should find out before you make that step.

Well, it is up to you.

DA 16-45mm f/4 + DA 50-200mm f/4-f/5.6 will be much better optical quality (especially in 16-45mm range) but less convenient to use, DA 18-250mm will be very convenient to use and less quality.

Think what is more important to you.

I have the 16-45 and the 50-200 and do alot of photo journalism type work. I use a slingshot 200 as my change table and anticipate what will be needed and swap out rapidly when I need to. The 16-45 stays on the camera most as it goes real wide and that means at night I can get closer and therefore my flash becomes more efficient when getting group shots as one example of a real plus for retaining the 16-45.

As others have said it all comes down to your shooting habits and anticipated needs. I don't mind carrying a bag all the time (three lenses and the external flash plus spare cards, spare batteries etc) where others would find that a real pain.

You don't know me but, you need to trust me on this - STAY AWAY from the 18-250 - It's a real dog!

The 18-250 is designed for the 'one lens' person who doesn't mind giving up a lot of quality in the photos for the convienence of a 'one lens does all'.. All sample images I've seen are very unsharp.

Best bang for your buck?

DA 16-45 f4
DA 50-200 f4-5.6

I own both of these lenses - both are outstanding performers.

The 16-45 is very sharp, easily my most used lens. A real joy. The only lens I'm aware of that works as well in this focal range is the newer Pentax 16-50 but, it's considerably more money and, although faster, might not be actually a better lens optically.

The 50-200 is a great bargain. It's sharp but more importantly, it produces the right colors and the bokeh is very smooth. There might be better lenses to replace the 50-200 but, not unless you spend considerably more money.

@ OP
Dont trust people you dont know, particularly dont trust people making bold statements like this. Check by yourself the images (there are hundreds) taken with the lenses you are speaking about and make a decission by yourself. Or even better, go to a store and try the lens by your own. I dont have all these lenses to compare, but from the tests seen in photozone and my own experience I would call the Tamron everything but a dog.

Come on tell us how you really feel I admire your passion - but I agree to disagree about your comments on 18-250.

So true! I just don't get why people buy an interchangeable lens system when all they want to do is slap one toally mediocre super zoom on it. It's total madness and a waste of money.

Those people should be getting advanced P&S not (D)SLR cameras
