18-55WR vs 18-135WR ?

Can anyone help me to compare the range of 18-55 from both lenses? Or redirect me to the existing thread.

I m also interested in comparing 18-55 ALii and 18-55WR, Are they optical identical?

Thanks.

I read that the 18-55mm AL II is optically identical to the WR. They basically added WR to the II to get it, but I haven't personally tested it or looked at the specifications.

Check our review: SMC Pentax-DA 18-135mm Review | Pentax 18-135mm | PentaxForums.com

The optical design of the WR and the II kit lens is the same.

Big difference in focal range between the 18-55 and 18-135.
If you were to choose between the two, and had the money for both, the 18-135 is an excellent choice.

If you look at the comparison photos in the link above, you'd never buy the 18-55 if you could use the 18-135 instead. Just select a couple of images from the same focal length and f-stop. I didn't examine the whole chart, but I didn't find any combination of settings where the 18-55 out performed the 18-135.

Wide open the 18-135 slaughters the 18-55, but actually by F11 the 18-55 has almost caught up. Worse CA though.

Thanks all of you.

I did a closer look this time. 18-135 is sharper than 18-55 over all, $500 vs $150, but maybe well spend $500.

I was consider 18-55WR as travel kit together with the 50-200WR. The 18-135 seems like a good all-round lens.

Can anyone redirect me to images taken by the 55-300? Is there a thread for this lens other than the reviews?
I may left the 50-200WR home as well.
Thanks.

Look for the DA lens club and you'll see lots of good examples of what the 18-55, 50-200 and 55-300 can do.

Also there are websites like Pixel-Peeper which are great for checking out what different lenses can do.

Also I like how Pentax lenses feature very heavily in the top rated lenses on that site - in fact I just checked and we now have 9 out of the top 10 lenses. haha. Brand loyalty or genuine class?

Strange that a lens with a much larger zoom range can have better IQ...?

IQ ~= Price / zoom range. I suspect that $$$ have a lot to do with it.

True. About the only reason to buy the 18-55 over the 18-135 is price. The longer lens is over three times the price. You do get something of what you pay for. The 18-55 is a tad smaller, but not enough to overcome the other advantages of the 18-135, if you can afford it.
