Hi all... :)

I got a Tamron AF Aspherical XR LD(IF) 28-300mm f/3.5-6.3 Macro lens. I thought it is able to shoot macro pics but I seem to have a problem snapping pics...

Do I set the camera to macro mode? Or do I use "M" since it's already a "macro" lens?

Or did I get the wrong lens? Or am I doing it wrongly??

Pls help... Thanks in advance! ;)

The lens u got is a general purpose zoom lense. Although it has a macro function, it isn't true macro. The magnification is 1:2.9 at 75mm. This allows u to go abit "macro" if u are taking small objects and gives u a slightly closer minimum focusing distance. U need to be at least 49cm away from your object in order for your lense to focus.

Although the official name of the lens includes the term "macro" (at least that's what it says on the box), it's really more accurately described as "close focusing". True macro lenses usually give 1:2 or 1:1 magnification and are specially optically corrected to ensure low distortion, flat field and high sharpness at very close focus distances. If u are looking into going really macro, u need a dedicated macro lense.

I dun really know which camera u're using but your preset macro mode isn't going to make the lense macro. And the "M" u mention i highly suspect its manual and not macro.

U could add some 1. reverse rings, 2. extension tubes or 3. close-up filters if u're on a budget to get slightly more magnification on ur lense. But these require u to use manual focusing; no AF.

Thanks bro... that's very detailed and good explaination there, really appreciate it... think I might have to go for a dedicated macro lens... :)

Here's a review of your lens...

esmondng, you may want to put a disclaimer or a link to the review that you copied your text from.
