Why does macro photography need more light?

best canon ef lens for macro image

Mike

I notice it especially indoors. When I zoom in on something small with my macro lens (canon ef 100mm f/2.8 non USM) I absolutely need a tripod to avoid camera shake. Is this normal? Does the USM version of my lens allow more light in?

Answer
It isn't just the light (although, if you get so close that your camera and own head shadows the light, that too), but also it's a thing about depth of field. When you shoot macro, at 100mm, at f/2.8 and very close to the subject - all three of these things (long focal length, wide aperture, close to subject) shrink your depth of field to be paper thin.

Move your camera just a notch between focus being locked and shot is taken, and your subject falls out of focus. It's not a motion blur that you'd see, you'd be just missing focus, because you moved your camera, not when that shot was being taken (you probably know better to hold it well at that time), but between focusing and shooting!

You may somewhat help yourself by closing aperture tight (f/11, f/16 or so), so that you get a slightly better DOF, but then... well, then you really do need lots of light for shutter speed to be decent, or else you'll get the actual motion blur you were talking about!

So either way - a tripod is a good thing to have when doing macro work... Or hold your camera absolutely still for the whole process - focusing and taking a picture...

Is this all i need to shoot bugs in deep macro detail?

Tha Syko C

I have a canon eos rebel xs

will this lense fit? ---> Canon EF 100mm f/2.8 Macro USM Lens for Canon SLR Cameras
Is this lens all I need to shoot macro of bugs and still life?
If I do need something else like tubes or a flash kit, what do I need?
Thanks in advance.

Answer
Great setup... I would also get a tripod and/or bean bag to stabilize your camera while you shoot so you can get a larger DoF. But I own and love that lens and it will work well with that camera.

I have used tubes with that lens, and while it gets you a little closer, it kills the working distance of the lens, which is one of its best features. Don't use tubes if you're shooting bugs; you end up needing to get too close to the bugs to focus correctly and they run away.

Good luck!

What would be the best way to sell a nondigital 35mm Minolta camera with a zoom lens?

best camera zoom lens image

what about

Since everyone is buying digital cameras these days, what is the best way for me to sell my older 35mm Minolta camera with a zoom lens and some attachments? Who would be most interested in such a camera?

Answer
You'll get the most $$ on eBay.

If the lens is an off-brand (like Makinon) sell it with the camera as it's practically worthless.

If it's a Minolta lens sell it in a separate listing. Same with Minolta flashes and other name-brand items.

You can also try craigslist and kijiji but in my experience auction is less hassle and nets you more bucks.

Hope this helps and good luck.

My camera lens wont open or close how can i fix it?

Sammie

My camera fell and the camera zoom lens 4x wont open or close i have a powershot A560 digital camera. How could i fix it? Or if there is somewhere i could take it for it to be fixed

Answer
The best thing to do is call Canon at 1-800-OK-CANON (1-800-652-2666). You can send it in to them to get a repair estimate, but don't be surprised if it is $125+ to fix it.

When your camera isn't in a padded case, you need to be using the wrist strap properly.
