I want to take macros like Jacko,which lens I need?
01/22/2004 11:28:54 PM · #2
He uses the Sigma 105mm macro
01/22/2004 11:57:00 PM · #3
I have that one too, it is GREAT!

I have the Sigma 105mm F2.8 1:1 macros lens also and I like it very much for the price.

I don't know if it really matters as I am no expert but I've got the Sigma 50mm f2.8 1:1 macro lens
It has an f stop range from f2.8 to 45
Not sure if the 105mm has got that. Also the minimum focus distance for the 50mm is 7.3" and the 105mm is 12.3" Correct me if I am wrong and I could be but doesn't that mean that the 50mm lens can be 5 inches closer to the subject and focus than the 105mm lens? I guess you could just ask Jacko:)

Yes,but what about magnification,and getting close up like 1 inch or so?

Yeh the 50mm can focus closer, but wouldnt the 105mm look like it is closer anyway, due to the higher magnification? It would also mean you can get 'closer' to insects before they get scared and skidaddle.

See now maybe I should have asked that question before I went and bought my darn lens. I'm still happy with it but as you can see I'm not the brightest bulb in the bunch when it comes to this photography stuff.

well the best way to learn is too ask stupid questions;)

I own and use a Canon 100mm USM f/2,8 macro and it's great.
01/23/2004 08:31:27 AM · #11
The Canon 100mm/2.8 Macro has ring-type USM, which means ultra-quiet, ultra-fast automatic focus with full-time manual focus ability without having to flip a switch.

This is an extremely sharp lens, making it great for "general purpose" use, especially as a portrait lens. Highly recommended.

the Sigma 105mm macro is an excellent lens.

Most of these were shot handheld with the 105mm.

The Canon Macro 100mm macro lenses are also great. There are two versions out there ... the older one doesn't have USM, so it's slower and louder. The one with USM has a faster focus. All three pretty much have the same optical quality.

Macro lenses are great because you don't have to get within an inch or two to get a great close up. The closest you'll get (unless you have extension tubes) will be 12 inches. And that is a big time close-up.

My silly Fly on Cactus is full frame (no cropping), however was shot on a tripod with miror lockup and remote shutter release, at f13 and 20 seconds exposure.

Jacko - your images are awesome. I want to get a prime macro lens at some point too, both for portraits and for critters.

Another option though is just to reverse a lens (like the inexpensive Canon 50mm 1.8 prime).

Here is an article about it (with plenty of amazing pictures - check out the rest of his gallery too) written by one of my favorite bug photographers, Mark Plonsky. The disadvantage of this setup versus a macro lens, of course is that you have to get in close (couple of inches) but if you look at his results, you find them amazingly worth it. (and many of his shots were taken with adapters on a Canon G1!)

Jacko,is This the lens you are talking about?
01/27/2004 08:21:47 PM · #15
Ordered new Sigma 105 mm f2.8 macro,as Jacko ordered ! :-)

Hmm... seems like I need to clarify some confusion about magnification.

All the standard macro lenses (Tamron 90mm, Canon 100mm, Sigma 105mm, Can/Tam/Sig 180mm) with 1:1 magnification will give you the same amount of magnification (i.e. on a 10D or 300D, fill the frame with a 22mm-wide subject). The focal length only affects working distance (i.e. a 100mm lens must get closer than a 180mm lens in order to achieve 1:1 magnification, but the 180mm cannot get closer to obtain more magnification unless you use add-on stuff like close-up filters and extension tubes).

The only exceptions are the 50mm macros (which do 1:2 magnification) and the highly specialised Canon MP-E 65mm that can do 5:1 magnification.

how much was the sigma?
01/27/2004 08:52:55 PM · #18
I want to take pictures like Jacko too but I know it takes more than just a lens. I would also need to gain the talen that Jacko has for seeing a photo oportunity and making it into an excellent piece of art. Although, getting the lens would be a start I guess. :-)

Holy Crap! Those are really great shtos! So good, they are creepy! Now, you took those handheld? Thats amazing! Can you use the sigma with different cams or what?

Nope, the Sigma 105mm is an SLR camera lens - you'll need an SLR or DLSR for that.

Sigma,WOW!

01/30/2004 01:44:31 PM · #24
pitsman, here is a thread i did a few weeks ago on using a 50mm lens and Kenko extension tubes, samples are here.

Kenko

you can get a 50mm f1.8 canon lens for about $70 to $80, and the extension tubes i got for $109. Kenko

this could be a lower cost alternative to an actual macro lens.

The Canon 100mm macro is the measurbators favourite lens



It's okay for other stuff too.


From what I've seen the Sigma 105mm and Canon 100mm are both far better than most people using them, so both great choices.
