Tamron 18-250 vs Tamron 28 - 300

I have the K100D with the 18-55mm.

I am going overseas on Safari.

I do not like changing lenses.

Is there a reason you can think of that I would not get the 28-300?

It costs $100 less, and all I'm losing is the 18-28 mm at the bottom, but gaining the 50 mm at the top. Plus, as long as I'm not going wide-angle and want the 35mm (equivalency) on the bottom, I can use the 28 - 300 for a walking lens.

What are your thoughts?

Do you have either of these lense?

What has been your experience?

If you have the 28-300, how are you shots at the 28 mm bottom?

Ease of use?

I would choose the 18-250 over the 28-300. That 28 is the equivalent of a 42 - a scary thought to me if it was my only lens. The wider angle is more useful than the extra big end. You can always crop a little around the edges to simulate a tele shot, but you can't add pixels to make it wider.

Agreed, whole heartedly, get the 18-250 and a teleconvertor.

I'm in the same boat. I'm going to Machu Picchu this summer and only taking one lens. I already own the 28-300 and really like it, but I do worry about the lack of a wider view. In my other travels, it hasn't really affected me, but it does nag at me a little. I think right now it's that you don't miss what you don't have.

I'm going to a Tamron-sponsored photo class in a couple of weeks. I've asked the camera store to make sure the Tamron rep has Pentax gear along with the boxes of Canon and Nikon gear they're sure to have. I specifically asked for the 18-250. I may get a wild hair and buy it then.

I've really been happy with my 28-300, though. I think the shots rival the ones I've taken with my DA50-200, except I have more reach. Mine's an older version that's full frame, so maybe I'm experiencing the digital "sweet spot" on this lens. However, except for a little softness at 300mm when viewed at 100% resolution, i.e. pixel peeping. When printed at 8x10 or viewed full screen, you can't see the softness.

Another factor is that I found my 28-300 new for $140. There's something about a bargain lens that makes me like it even more. The 18-250 will have to go some to beat it in my book, but from the Pop Photo review, it looks like a nice super zoom. We'll see, hopefully.
