guys, i want to buy a macro lens

either a efs 60mm or ef 100mm, $370 and $470 respectively

i will be using these for bug chasing, do i need a ring light too or no in day time

i have a speedlite too if that matters

Christ, you're easily persuaded to splash out an extra $100.

canon has cashback right now

the efs will be useless when i eventually get a full frame

and 60mm is close to my 50mm, might as well get 100mm which can work as an 85mm, except longer

you know what i mean

Wow, someone who's actually thought about it before asking /p/. Nice one.

I wouldn't think you'd need a ringlight for daytime shooting, you can easily DIY a simple one with your Speedlite if it turns out you do need one.

nah, he just reckonizes the supremest force that constitutes my power of mental thinking.

respeck, fool!

or maybe i could buy the 100mm and the ringlight and get double rebates on both

awesome

will i be able to handhold this bitch or do people use tripods for this kind of thing

I've heard that the 100mm is an amazing lens. Might as well grab that since it's future proof for full frame.

Dude, if you want substandard choices, go for the gold. Get the digital-only lens or the Sigma that'll start having problems in six to twelve months. I understand that my view isn't held by all, nor should it be, I suppose. It's just a product of necessity.

tamron 90mm with 2x converter.

problemo solved

extension tubes for macro, TC's are a neddy no-no for macro
>> heman
for bug chasing. the 150mm sigma is 1:1 and meant to be not bad

I've got the 60mm autofocus macro for my D200.

My neighbor bought the Canon 100mm autofocus.

Then off we went to the folowers.

60mm was a dumb idea. I have to get the flower up my nose to capture it, and don't even ask me about the wasp picture.

That being said, handheld is a breeze, but AF usually gets turned off.

Dont' have a ringlight - wish I did. Even at teeny tiny apertures, depth of field is a bitch. The best macros I've seen use a tripod and walk the subject front-to-back with some after-the-fact merge of 5 or 6 photos to cure the depth of field problem.

someone mentioned the sigma 150mm, which includes a hood and tripod ring for $100 more so i was interested

i read a review and it says this:

"It is quite interesting to note that the lenses looses between 1.5 to 2 f-stops in speed when set to the min. focus distance. This is in line with other macro lenses featuring an internal focusing (IF) mechanism."

what does that mean? sounds like a disadvantage

the canon 100mm has internal focus too (doesn't extend or move when focusing)

this means that when focused to minimum distance, your lens behaves as a f/5.6 one despite the camera telling you it's set at f/2.8.

okay, and with a lens that focuses by extending, that won't happen

but then i have the inconvenience of an extended barrel

is that it

The 100 macro is an amazing lens - it's also still good for your kit when you beef up your regular lenses; even with L glass and a full-frame you'll find it a useful piece of kit. I've used it as a portrait lens, and as a macro lens.

Looks like you've already made your choice for the 100, and for that you get a thumbs-up from this end.

well no

i'm still confused about the internal focus being inferior thing

I've never heard of this before. Link to the article or some proof?

from the article on the sigma 150mm because someone suggested it

i don't know what it means but it sounds like a negative thing

It just means that the closer you focus, the more light you need. Example is that the 60mm has an aperture of 2.8. but when I'm focused all the way in the camera reads it as 5.6. As the article says this is fairly common, it's just one of the reasons macro photography requires so much light.

At its most basic, focal length is the length from the lens to the focal plane. The physical length isn't really equal to the focal length anymore, thanks to more complex multiple-lens optics, but there's still the basic relationship there. When you give your camera some extra macro ability by adding in an extension tube, you're increasing the focal length (thereby increasing the magnification) while maintaining the same minimum focus distance.

Dedicated macro lenses basically do the same thing, just with the "extension tube" built into the lens--either by physically extending the front element much much farther than non-macro lenses, or by doing the same using floating elements inside the lens barrel.

The same is true for regular lenses, actually. I've got a fixed-lens film SLR where you can physically see the field of view changing when it focuses because focusing changes the focal length slightly. With most lenses out there, though, the change in focal length when you focus is small enough that it doesn't make a noticeable difference (or maybe it's engineered away. Like the maximum aperture of the lens might actually be f/1.75 when focused at infinity but they limit you to f/1.8 to match its maximum aperture at its minimum focus distance)

okay so should i get one that has internal focus or one that extends while focusing?

i've looked at them, the canon 100mm and ef-s 60mm are internal focus, same for the sigma 150mm

there are cheaper ones like the tamron and sigma, not sure what mm, but they extend while focusing
