Tamron 28-75mm 2.8 question

[sugar_babygirli]

Hey there!

I just got my Tamron in the mail today and was curious as to why it says MACRO on the box? Are there two different Tamron 28-75 2.8 lenses and one is macro, the other isn't?....because I didnt order the macro one as it's going to be used for mainly wide-ish angles, full body shots, etc.

Will this work even if it says Macro? Lol :confused:

[mr.photoguy]

yes it will work.
It just has the ability to focus really close.
That's why it says Macro.

Enjoy your lens, and please post a sample image @ 2.8 ...
I would love to see the results..
Thanks

Ok great so it will work? What I'm really curious about, though, is if it indeed is the right lens or do they have another lens the same specs, but without the macro feature? That's what I'm really wondering because how can someone use a macro to take a full body shot?.

Me confused a bit. :o

Its the same lens that everybody is talking about..........mine had the Macro logo too. :-)

The word macro is probably a bit misleading - a marketing ploy. More people will buy when they see that written on the box. Think of it as a normal zoom that focuses closer than most.

A real macro can give you up to 1:1 or 1:2 images.

[mr.photoguy]

To be honest, I am impressed with how close it can focus... nearly 8 inches, or so..
The Macro symbol is pretty well deserved.

Ohhhh ok I get it now! Just took some test shots as well and it does INDEED focus closely, but also is extremely sharp zoomed out fully. Thanks so much for the help and explaining!

Forget the word "macro" on the lens, and check physical magnification (reproduction ratio). None of these zooms are macro, but they do useful close focus. The Tamron 28-75 has a mag of 0.26x (1/3.9) at 75mm focal length at 330mm focus.
This means on my 20D sensor of 22.5x15mm size, a subject of about 88mm x 59mm will fill the view. Not macro, that's marketing hype, but useful close focus. Macro, or 1x reproduction means an object 22.5x15mm will fill your image. You can work this math for your sensor if it's different. I use the Canon 100mm 1x macro.
Take the magnification of any lens, 3.9 in your case with the Tamron, and multiple it by the sensor dimensions. That will tell you what size image will fill the view!
Hope that answers your question? Jack

There's only one Tamron 28-75, "Macro" was put on the box by marketing people, not engineers. It's not a real macro lens, it's only 1:3.9, real macro is 1:1 at the minimum focusing distance. It's a good lens, it's just not really macro.

Canon's 24-70 does the same thing.

Yea, means nothing really. It can definately do full body shots don't worry. It just says macro on the box, because to some degree it does have macro capabilities. It can focus at reletively close distances, and get a shot of a flower or something. That can be considered macro. True macro is where you can get a shot of a flies eye ball. Or a full frame shot of a bumble bee and see ever last hair on it's body. See what I'm saying here? So, don't worry. It's not truely a macro lens, it just has SOME macro ability to it.

Ok I get it now! :D Thanks to all who replied!
