This is a follow up to a few other recent questions about shooting artwork including: macro lens for artwork with the T2i
I just received my T2i and tethered it to my laptop. With the stock lens it seems I can Auto Focus, and basically set up and take the pictures, all tethered the laptop. I'm very pleased!
- Can I manually focus from the laptop (I wasn't sure how but sometimes that wil be needed)?
- What is the advantage that a USM lens would offer? Or is USM what I need to manually focus tethered?
It seems like I should go with one of these three lens:
- Canon EF-S 60mm f/2.8 Macro USM
- Canon EF 50mm f/2.5 Compact Macro USM Lens, or
- Canon EF 50mm f/2.5 Compact Macro Lens (non USM)
The T2i says it is "EF-S". Can I only use these lenses or are the EF ok too?
The compact macro lens don't offer true 1/1 but they are cheaper and still remain distortion free. (as least that what I'm given to understand?)
- But I was also wondering if there is a zoom lens that will offer a low distortion result? (Primarily the problem with artwork is the bending around the edges.)
With about 1000 works to shoot I reckon it will be a lot easier If I didn have to reposition the camera for every shot. I'm hoping maybe to be able to zoom a little (not much) to each subject to make it fit nicely for full resolution. And if I can zoom and manually focus from the laptop it will obviously save a fair amount of effort. My primarily concern therefore will be making sure the subject is centered on the stand. And then I'll only have to move the camera when when I have a significant change in subject size.
I hope this makes sense! Maybe I don't need USM? Maybe zooming isn't possible tethered? Or maybe it is possible but will have too much distortion?
Also, I do have some room, up to 10' from camera to subject. And the largest artwork I'm shooting is only 30"x40" (average is probably 18"x24"). Is there any advantage to going with a 100mm Macro Lens instead of the 50mm or 60mm?
