18mm


11mm


and again 11mm

I think I picked up a winner although these are just fast edit shots to test the lens out and check for any chromatic abberation and speed of focus.

 

I can't see the windows from that picture. You suck.

 

I thought this was gonna be about beer. I'm severely disappointed.

 

Time to clean sensor? h:

 

Shit! your right h:

Oh well 2 minute job.

 

I take it this is the Tamron 11-18mm f/3.5-5.6 EF-S?

How well does it focus without USM? My only experience with non-USM lenses was a long time ago (Sigma 135-400, and Tamron 28-105/2.8), and at that time the lenses focused rather noisily and slowly.

 

No this is the Tamron 11-18 4.5-5.6 DiII lens.

The focus is actually faster than my Sigma 17-35 2.5-4.5 and weighs considerably less.

I know I should have gotten a faster lens but this lens is going to be used mostly outdoors in glaring sun or with multiple flash units. Since it's a wideangle DOF isn't a major concern either since wideangles aren't really known for amazing DOF anyways even in their faster forms.

 

Er that's what I meant, I just put in the wrong aperture and called it "EF-S" since that's what DiII means. h:

 

Thats what she said :chuckles:

 

If you are talking about Tamrons DiII system being their equivelent to Canons EF-S system then that is incorrect.

The EF-S system satnds for Electronic Focus Short. This is how it works.They are able to make a lens that goes further into the body because Canon digital bodies are of course not a full frame 35mm sensor. If you were to mount an ef-s lens to a 35mm film body the mirror would hit the glass of the lens and damage one or the other. To make sure no one used such a lens in a full frame body they made a different mount called the ef-s. Unfortunalty the EF-s lens technology wasn't made untill after production of the 10d so the 10d doesn't accept EF-s mount lenses.
