gjtan: well, theres no lens out there that doesnt have any weaknesses (well.. maybe but I cant afford it..

) for the 18250 or 18200 or most big range telephoto, i think ud have to compromise on the image sharpness at the tele end... ive used the minolta 100-300, Beercan, sony 55200 and sony 75300...if i would rank them... the beercan would come in first... but only by abit compared to the 55200... id place the 100-300 last because it tends to get soft and around 250-300 and also CA is pretty much noticeable... if ur planning on a telephoto lens.... id say get the beercan or if ur tight on budget definitely the 55200...
55200 + 1855 would beat 18200 any day in my books - (but since u dont want the hassle of changing lens.. try the 16105...)...
*the usual disclaimer applies
jimon: if you want me to do a comparison then i can show you both photos from both lenses...
+1, same here. 55-200 anytime over 18-250

You cannot compare it like that. The two lenses are built for different crowds.
For sure the 55-200mm will beat the heck out of the 18-250 in the same ranges both in terms of IQ and aperture ratings but the 55-200mm is specifically a tele lens. You cannot leave the 55-200mm attached to your camera and go out with just that one lens. You will probably miss quite a number of shots if you do. (Landscapes and groups come instantly to mind.)
The 18-250mm however is designed to let you attach that one lens and go out and you'll still be able to shoot most of anything. The price you have to pay for that convenience is to sacrifice a little in terms of IQ and aperture rating.
For a person to cover the range from 18-250, he/she will have to bring at least 2 lenses if they do not want to use a superzoom. If he/she has only one camera body then he/she will need to swap lenses to get to use the different focal range.
Imagine that while out for a little stroll during your vacation, you see a new species of bird never seen before in this world. It's about to take off and go into the woods where no one will probably see it ever again. Standing where you are you can get a decent pic of the bird at 200mm focal length.
If you had the 18-250mm attached on your cam you could zoom all the way and get a decent shot.
If you had the 55-200mm but it's not currently attached to your cam, you would probably have lost the bird in the time it took for you to change lenses. If you have had the 55-200mm attached, you would have probably gotten a better pic of the bird in terms of IQ and exposure compared to the 18-250mm but that's a big IF.
That's the difference between the 2 lenses.

cutting all the jumbo crap.... 55-200 is indeed better in all forms of "photo result". (putting practical aside)
(if u were to go birding, noone carry a 18-250 for birding, they carry straight a 70-400G LOL... kidding

i carry my 200-400 for birding)
johnmeng: u dont think u wan CC, sure get bomb only, in a photographer eye, that hurts the eye. massively UGLY HDR.
shootkk: yo bro, i shoot wedding too, my opinion,
i. get 2 body.
ii. upgrade ur anticipation skill. always change lens before the fall of event. knowing the event is very important.
iii. i shoot a whole wedding with just a 50mm, not just once, but many times. and they still stunned with my work.
-----------------------------------------------------------------------------------------------
18-250 is nothing. i sold it off after 1 year sitting in by drybox when i realize my 18-70 and 55-200 can do sharper photo.
summore, 250mm (for wedding) that distance, ur flash cant even efficiently be used la...
i can change my lens in 3 sec. i remember once the F1 (Ferrari team) missing 1 wheel during pit, the next following 30 days, all crew are to train pitting non stop whole day for 30 days. hence, today, Ferrari team has the fastest average pit time. so... PRACTICE changing lens improves you.
and to be honest, how many times a person need or fully uses a tele INDOOR?, i might just take that few step forward to snap with my 18-70/55 (i using 17-50F2.8 as kitlens)... and pls pls stop BS like that few step u lost the moment.... u should have anticipate that moment if u intent to go pro.
BUT if u are just a family man that wanted to shoot ur kids or at birthday party or picnic at the beach, just get the 18-250 and
IGNORE the IQ, because it is already at the best it can offer. and u will not use the whole 1xmp to do a 50x40 large print (do u?) at most, u will put as ur wallpaper (fullHD is only less then 3MP) or 5R prints which only require 2mp to get max sharpness off it.
u are better off spending money on a F58....
