Comparison of photographs. DA 18-135mm/3.5-5.6 , DA 70mm, Carl Zeiss 28, 50, 100mm

I suggest look at the pictures, which I did on the K20D

DA 70mm / 2.4,
Carl Zeiss 28mm, 50mm, 100mm / 2.

All photographs are taken from the same tripod position.
All photographs to http://photobucket.com I put them full size 4672x3104.
You see size 1024x680
DNG to JPEG inside the camera K20D.

Exposure 1/125.
Everywhere one.

Aperture
18mm / F3.5
28-70mm / F4.5

With a DA18-135 WR on order I sure would like to see your pics. Too bad they only show up as little red X's.

You can't post photo's that size. See the rules for posting pictures.... You can add a link to the photo's though.

Thanks for posting those. It may take some pixel peeping to see the differences, because they aren't immediately obvious on my screen, and that is a good thing.

Thanks for the shots.

Was the focus point on the building in the background?

I shot at the white fence.
Probably the camera K20D hit on the building in the background.

thanks for shots
interesting is that zoom receives more light than primes
i have a thought that there are some focusing problems in shots.

Thanks for posting these. Between these, Adam's review and other shots I've seen I think the 18-135 fails to deliver sharp enough shots for my liking and I'm going to skip it.

I think it is sharp enough for day to day use, I dont realy think one could/should expect too much form a lens like this... But after forst repeorts many seemed to believe that this lens would have limited IQ...

That's the problem though - it's not really priced as a 'day-to-day-use' lense. I already have a Sigma 18-125 that hasn't seen the light of day for 6 months at least.

If the 18-135 is not a huge improvement on the Sigma (I was hoping it was going to be) then I don't see the point (for me) and I would rather pay the extra and go for a DA* lense.

Mine was not used much either but that was because lazy yours truly got the 18-250....

It does have 10mm extra on the long end!!! . But yeah it will be nice to test those (and the 18-250) head to head as I think those are the major competitors for the 18-135 (I think I'd rather have a 16-125 but okay, one cannot have all).
From what I see here the DA* lenses covering this range do have better IQ that warrants the higher price BUT at 50 on the long end for one lens and on the short end for the other I find myself swapping lenses too often which annoys me as once you have mounted the 50-135, you are bound to see something that requires wide angle and the other way round ofcourse (that is, even thou I appreciated the IQ of the DA* lenses and primes, for some of my favourite subjects (action stuff like combineracing, tractor pulling and lawnmowerraces) I have often just used the 18-250 .. And when conditions more or less require WR, changing lenses may not be a good idea.
