I've decided to take the plunge and go for a dedicated macro lens. I would like to take photos of insects, therefore I need a lens with a decent range(i.e. greater then 100mm). I have no real brand preference.

Which macro lens out there offers the best value for money?

I was thinking of either the Sigma 105 2.8 or the Sigma 150 2.8 but I'm open for any other suggestions (please note, this will be a dedicated macro lens).

John,
I have the Sigma 150, and it's a great lens - very sharp and you can have a nice working distance between subject and lens. However, just as with a telephoto, the longer the lens, the more necessary a tripod becomes. It feels like lens movement is more of a problen with a long macro lens and higher magnifications.

Hi Ron, Thanks for the advice.

I forgot to mention, most shots will be taken in a controlled/semi controlled enviroment, with a tripod, therefore feautures such as IS are not too important.

Some other considerations I have are, is it worth getting extension tubes, if so, what length? The same applies to tele convertors.

I've now narrowed my search to:

Canon 100 2.8

Sigma 105 2.8

Sigma 150 2.8

Any more macro shooters out there?

What do you shoot? Statics (indoor) or critters/flowers (outdoor)...

With a 1.6x crop camera would Sigma 105/2.8 make more sense for outdoor (critters/flowers)and indoor macro/portrait photography?

I have seen test reports where 105/2.8 is a little better than 150/2.8 in MTF.

How can anyone says that?

105/2.8: 150/2.8:


The 150mm is definetely better outdoor because one will not scare the bugs away by getting too close due to the greater stand-off distance - A 50mm f/2.8 would be better indoor especially if you work with a stand for photographing small articles, and a 100mm is a compromise between the first two...
Bear in mind that only the 150mm (and the 180mm) has the HSM though :idea:

First of all there's no such thing as a bad macro lens - People who buy theses things expect excellent results, so here's the MTF for the Canon:



-> You tell me which one is better according to the MTF?
Remember the blue curves are when the lens is closed down and the red and green are wide open (i.e. black lines on the Canon) :idea:


The Canon 100mm does come with USM which the Sigma 105mm is lacking (justifiable by the price differential), but then that's why I picked the 150mm EX which has the equivalent HSM instead...

Remember theses are macro lenses so you'll be using the manual focus most of the time (if not all the time). So the speed of the AF is not an issue here, but what the USM/HSM allows is the full-time manual overide which is nice... You don't have to pick AF or manual focus, but just simply twist the focusing ring by holding the shutter release 1/2 way down - That's just how I shoot

Thanks NHL

I'm having a hard time choosing between the Sigma 150mm and the Canon 100mm

To the Sigma's avantage

- Extra reach, will be really beneficial if I ever go full - frame

- Better build quality (Sigma's EX range definately better then Canon's non-L range)

- Better for insect shots

To the Canon's advantage

- Possibly more suitable to a variety of subjects

- Always nice to couple a Canon lens to a Canon body - not really that important though

- Has less quality control issues (photozone.com tester had a bad copy of the Sigma)

Overall, if I was gauranteed a good Sigma copy, it would be an easy choice, I'm buying from BHPhoto but live in South Africa, so I may encounter problems returning a bad copy.

IMO - It's up to you, the extra cost of the Canon is like an insurance premium to get a 'good' copy...
-> but then it depends where you are because in the States the Sigma EX is guaranteed for 3 years so you can return the lens (if there's an issue) quite a long times! :-) :lol: :-)

Someone mentioned 4/5 years warranty in Canada so it'll depend on the countries
