100/2.8L macro vs tamron 90/2.8 macro - Page 2

post #11 of 17
For a product shoot, I don't think anyone will notice the difference honestly. Who pixel peeps a product shot (besides us)? Any halfway decent macro lens will plenty sharp for a smallish shot on the web (unless of course the shots will be big wall prints for a shop).

it is a product shoot for web, but i want to get as sharp as possible cause its handcrafted jewelry so i want to show off all the details and they are going to have a magnification plug-in. not sure if it will be at 100% zoom for the plug in tho.

plus hopefully it will be an seasonal client so i want them to be happy.

if it's for jewelry and small items, i'd get a tamron 90 f/2.8 and use the savings towards a used microscope stand and macro ring light.

the real way to do macro product shots is attach the camera and lens to the microscope stand. then adjust focus using the microadjustment knobs on the stand and not the focus rings on the lens. make sure you have a remote release. if your camera supports tethering as most canons do, even the rebel xti, use that to release the shutter.

also, be critical that the camera is completely level and flush (pointing strait down) relative to the stand. that way you don't introduce trapezoidal effects.

You are dead on on what I was planning. I borrowed a macrorail and am going to tether a 5d2 for the shots. I am not going to use a ringlight tho cause the light is too flat to show off the facets in the gems, instead I am using a few led lights to get some "bling" out of the gems. At least that is my plan but I don't have the jewelry yet so I don't know how well my plan is going to work out.

That sounds fascinating. I'd like to see the end results (understood if your client would prefer you didn't post though)

I'm sure I can post something, since they want me to sign the release forms lol.

I'll try to get some set up shots too since I find those more interesting when i try to learn how to shoot.
