It's a very nice image, but "sharp" isn't the first word that comes to mind for me.

to me it is since its a step up from an 18-55 and 50mm 1.8 lol

The 18-55, well, yeah - pretty much anything is a step up from that, I'd agree, but your 50/1.8 should have the edge for sharpness, especially from about f/2.2 onwards.

The main thing is that you are happy with the lens you now have, and clearly it and you are capable of producing excellent images.

I had the 28-135 and it produced some great images. It is a good lens. Work with what you have learn your camera and the limits of your lens, and then upgrade in the future....

Nice shot...

I enjoyed mine for a good while =)

Mine is as sharp as my 24-70L ,I love it

At 2.8 your 50mm should be your sharpest lens. Mine is and i love it, despite what is said on this forum about it.

28-135 is a good lens. Needs a better IS system and better build IMO.

I think the problem is that most get it to shoot faster than f2.8 - which is where it is not good. If you just consider it an f2.8 lens, then it is not bad at all. Surely the ring USM coupled with slower apertures and more DOF would make the 28-135 a big improvement for AF performance, though.


As for the OP. I think this is a nice photo, but not a perfect example of sharpness. If you want to test for sharpness, you need something with a lot of detail. This photo just has a pleasant softness and nice contrast to it.

I must've had a bad copy because mine wasn't sharp even at f/8. Maybe it just didn't play nice with my 10D...

I like the 28-135 on a FF. On a crop sensor its a little short on the wide end.

My 1st lens had a slight front focus from 70-135mm that you had to step it down to F8.

Got a 2nd lens and same thing, decided to send it to Canon. Had to send it in twice they claim no fault found the first time. I told them on the 2nd service if you test the lens at 50mm it would be fine and if you read my service issue I said between 70-135mm it tends to front focus. It came back perfect at all focal length.

At the longer focal length wide open at F5.6 its way sharper than before service at F8.

At F5.6 @80mm no post processing sharpness in camera at 4.

for the price, you can't shake a fist at it.
