actually i'm thinkin to fit 2x on 100 macro for potrait or wildlife use , so i don't need to buy another tele lens ,
anyone ever tried this before ?
and will my 450D able to AF ?
thank you,

Ok, few of my thoughts:
- did you read the link to the FAQ I gave in previous post?
- as I just posted, you'd need to get the Sigma 2x TC unless you use tubes as well.
- with the 2x TC you lose image quality. There is also some loss of IQ with the 1.4x TC, but not as noticeable.
- with the 2x TC you lose 2 full stops of light, so f/2.8 lens effectively becomes f/5.6 len max aperture. Think that's the limit of AF effectiveness?
- the 100mm lens is fine as a portrait lens without 2x TC
- the 100mm with 2x TC is probably too short for wildlife, but depends what you're shooting. Typically would have thought you'd be after at least 300-400mm lens for wildlife. I have the 100-400 L. Plus for wildlife would think the loss of IQ is unacceptable.
- I'd recommended researching more whether you'll get AF with the Canon TC + tubes + 100mm lens. Table in the FAQ says you do with Sigma.

Personally, I'd get the Sigma 105mm macro lens (this will do your macro and portrait work), and with the bucks you save by not getting the Canon 100mm and don't buy a 2xTC, put it away towards getting a more "conventional" wildlife lens soon.

I agree on this to a point. It depends on how much macro/portrait you do compared to wildlife.

I use a Sigma 100-300/4 EX for wildlife and I find I am often even needing a TC on that (it still produces excellent shots with a TC by the way). I just don't think a 100mm lens is long enough for wildlife. Now you may see people using 200mm lenses for wildlife, but you'll find the IQ you get from a 200mm prime will be far better than a 100mm macro with 2x teleconverter.

If you are more into macro and portrait I'd invest in a Canon 100mm macro. It has nicer features compared to the Sigma. Save up a while for a tele lens for wildlife. Perhaps you could look at the Sigma 100-300 EX for that side of things as it won't cost you an arm and a leg and it is an excellent piece of kit.

hi all i'm intersted to buy this lens for general purpose, potrait and macro and indoor sports
i have question though, can this lens be fitted with 1.4x or 2x Tcon? canon or 3rd party one ?
and what f it's gonna be when fitted with 2x tcon ?
thank you , sorry i'm still beginner :P
thx.

Not recommended, compatibility with the Canon TCs with a tube fitted also so loss of infinity focus. An independent might work OK but 100mm is a bit short for a TC to work well. Macro is demanding on lens sharpness so adding a2X gives a bit hit on sharpness, probably less of an issue at low magnifications.

Take a look at the 200mm/2.8L, an excellent and lightweight lens that is very sharp and a lot less expensive than some. Is compatible with the Canon TCs and takes them very well to boot.

I just ordered this lens from B&H today after looking through this thread with great envy for the last few weeks, especially staceyann and her ridiculously good photos.

how did i do ? please CC .. im just starting to learn about macro

^^^IMHO, I wouldn't consider your shot a macro, per se... I would shoot a tighter shot at one of those components (e.g. blue 'On' switch) with some bokhen would be better. Happy shooting!^^^

yeah, you're right ... now where are them bugs lol

It does demonstrate how versatile the lens is though. On any normal lens that would be about the closest you could get, but with the macro you can go much closer if so desired. I find it very useful in composition and not having to attach tubes etc when your just not quite close enough is a Godsend

Heres my first pic with this lens,

Just got mine in while I was at work today. Here is my very first shot with this lens, nothing special, just a handheld shot at my cubicle...

haha, that first cat shot is pretty cool looking. It appears as though it's ready to pounce out of the picture at me because of the way the paws are cropped off. It makes it seem a lot closer. Good stuff.

Hi,

Just bought this macro lens. Did some self test at home. Here are some sample. All photos are straight from camera. Pictures are not post processed except resize and cropping.

I've had this lens two weeks now - there is a bit of a learning curve to go with it and you don't realise just how much it likes a bit of stability until you try it. IS would be nice.

The shot is the innermost workings of a Rhododendron.

Interesting post. I like it a lot, but I'm not sure it demostrates the capability of the lens...
