This is going to sound silly, I'm sure but I have a question in regards to some lenses I've been looking at...
Unfortunately I can't afford a Nikon 24-70 so I've been looking for alternatives... but there are a couple of Sigma lenses that come close... 24-70 2.8, the both of them. Now... I've seen two versions - one is a macro.
The specific lenses:
Sigma 24-70mm f/2.8 EX DG MACRO Lens and;
Sigma 24-70mm f/2.8 EX DG HSM Lens
The macro is significantly cheaper than the HSM.
Can someone please explain to me what the difference is? Possibly in blonde-girl speak?
