I don't know the 55-300 but I have a Sigma 70-300, and long story short, there's too much loss of image quality to do that. But, just rambling on, my current thoughts are maybe selling the 18-135, although from 18-70 it is an improvement on the kit lens, and it's still sharp in the middle at longer lengths, meaning. It really sucks at the edges over 70 mm, but, if you centre your subject you get amazing bokeh.. but, it's heavy. Now I'm thinking, 21 ltd and 35 ltd macro. I have to get my 21 fixed, but, it's image quality was way beyond any zoom I've seen in that range, and I'd hope the 35 would give me the range I need in the wide angle end of things. My 60-250 on the other hand gives me image quality comparable to any prime I've seen. I don't feel I'm sacrificing IQ by using that lens. By the way, the 10-17,18-135 and 60-250 is my travel kit as well. I'm just feeling the 18-135 is probably the weak link. Using the 21 ltd. and seeing the images that came from it has only reinforced that feeling.

I have the 18-135 (recently acquired) and I like it a lot; my travel kit will be 12-14, 18-135 and 55-300. The three lens setup is light enough... however, it seems to be missing something for indoor (with flash) shots that I am missing f2.8-3.2 range. A 21ltd, or 31ltd. would be ideal to add as well.

Since I'm carrying the 60-250, heavy but worth it in my opinion, I'm only really using 18-60, and I have a 50mm 1.7. The iQ of the 60-250 is probably better than the 100, the 135 or the 200, very close, so it effectively replaces at least 3 primes, hence my willingness to carry the weight. I can't think of a single prime the 18-135 comes even close to. Therein lies the problem for me. That being said... I walk around with the 18-135 on my camera all the time. It's very convenient as a snapshot lens. The range is excellent, I just wish the optics were better.

Agree; the 18-135 range is convenient, well-built, good optics but it could be better (optically and speed). Don't know if it is technically possible or not, constant f4 throughout the entire range (may become a huge lens); or even 3.2-4.5 would be really nice.

As for the 60-250 (though I don't have it yet), no doubt it is one of the best, I agree that it is a bit too heavy to carry for travelling. For cruise may be... but for hiking and land travel by bus, it will be a bit too bulky.

I've already carried the 60-250 25 km ( 15 miles) on my back in it's first year. It's not that it's so heavy it can't be carried. And if you look at the alternatives.. any 200mm+ 2.8 lens is going to be twice the weight. A lot of your high IQ telephoto's are up over 15 pounds. The only thing missing for this lens is the 1.7 converter. If I can get one of those my hunt for more reach will be officially over. My problem so far with the 1.7 is, when I have money they are never available. I might have to open a special bank account just so the money is waiting for the next one advertised.

Someday, I might just pick up your advice; to add the 60-250 and 1.7 teleconverter for hiking, birding and wildlife expeditions.. Arh... my LBA is kicking in again!!

I like the DA*16-50mm so much that I bought two of them. I use this lens all the time. I got the second one just this week so I'll be ready for my second K-5.

Im generally pretty happy with my 16-50, the extra stop has actually been invaluable for getting good shots when Im running round almost shooting from the hip in a low-lit night club without the flash, K7 high noise and all. Anything slower just wouldnt have worked.
The 18-135 seems like a good range, probably equivalent to my old Tamron 28-200 film-era superzoom, though I guess you expect some limitations with such a large zoom range
(and yes, I have the 18-250 also so Im not just a fast zoom/prime snob!)
