What exactly does the macro switch do? Decrease min focus distance? Does it actually move an element in the lens? eg. what is the difference between shooting an insect at 250mm with or without the macro switch enabled?

The switch allows you to move closer to your subject, i.e. it does decrease the "minimum focusing distance" of the lens, which in effect turns it into more or less of a magnifying glass so you get far more detail than using the standard zooming function of the lens. What's cool is if you pick up some inexpensive magnification filters you can get quite fine detail of small objects in combination with the macro feature. I don't know if any elements are moved inside the lens.

Under the manual focus setting, you can still press the button half way down as normal, then fine tune your focus with the wheel. You will be able to then turn it to the area needed for macro range.

How does the macro fit on the camera? The fisheye part threads on but doesn't take focused pictures, the macro and fisheye doesn't seem to have any way to fit on? This came with NO instruction manual so I'm at a bit of a loss.

Macro lenses are by design usually better than most prime lenses. In this case my Nikon 40mm will out preform most of my very expensive primes. And yes they carry this performance to any distance.And contrary to the other commentary it will focus accurately at any distance including infinity. I know because I use it thus many times a week.

No it does not. You will need to set your camera to Aperture priority and then set the f/stop on the lens. Nor will it autofocus a lens. This is best used if you have an older fixed f/stop lens or are using a older macro lens.

Thank you guys, really appreciate you help. I was in confused state in selecting sigma 50-150mm f/2.8 or tamron 70-200mm f/2.8 macro, but after a week study i have selected this sigma 50-150mm which is exactly in my budget. Once again thank you guys.

works great for macros! seriously this lens is amazing for the price. You do need to be 2-3 ft away but works and looks awesome!

You need to push a button and slide the focal ring so the ring shows it is in macro. Just push the button above the macro button and slide the focal length ring to either manual or electronic focal length adjustment. It works with all modes including manual.

It can focus pretty close at all focal lengths, but it doesn't have a formal "macro" position. There's a discussion of this on cameralabs site, see the review of this lens. He claims a magnification ratio of 1:2.6 is possible. I haven't measured it myself, but it is a good lens for closeups.

This lens does not have the MACRO option, but can focus down to 4" at 18mm ... I just tried it.

You screw it onto your lens just like a filter. You then focus the same way you would without it. It allows you to focus in much closer than with just a non-macro lens. It works really well.

Canon EF 100mm f/2.8L IS USM 1-to-1 Macro Lens for Canon Digital SLR CamerasHello:I am a Canon newbie and have recently bought my starter equipment. I bought the T1i Canon kit that I found on the amazon.com site. I have now begun to shop for a macro lens and am considering the one indicated by the link. It appears to have the IS feature which is what I was looking for. After reading the reviews, the only negative thing that I have noticed was the price! I suppose you get what you pay for. Any thoughts or suggestions would be appreciated. Canon EF 100mm f/2.8L IS USM 1-to-1 Macro Lens for Canon Digital SLR CamerasHello:I am a Canon newbie and have recently bought my starter equipment.

Yes, this lens does have the option for auto focusing. But I clearly find that manual focusing is the better of the two choices. Unlike some lens, this option to change from manual to auto focusing is done by sliding the forward most ring, the one closest to the len's end back and forth. No switch. There is no automatic zoom option. You have to rotate the ring closest to the camera body to zoom in and out. I guess that is why I prefer the manual focusing. But either way, I am very happy with the photos I have taken with this lens. Hope this helps

I wasn't aware Sigma made this same lens in a "macro" version? Becarefull believing the discriptions as some "used" products are misrepresented. Any how, macro will allow for a shorter minimum focus distance. Good luck

I would suggest getting the 105 mm macro if you want a true macro for closeup photography with any Nikon camera. I've used this lens for four years and have been extremely satisfied with sharpness and bokeh. At extreme macro settings, autofocus should be turned off, as it has difficulty searching for focal points. A 1:1 macro ratio is achieved when end of lens is approximately 5 1/2 inches from the subject.

Hi personally it did not work for me. The camera becomes set back so far as a result of the mounting that focussing is a problem. For me other than macro work it was not suitable and certainly not as all round useful as I understood it to be.I returned mine for a refund
