Canon 24-70 f2.8 / MACRO?

[andrewaaa5]

I know this lens is not macro, but is anyone able to post some photos at the 70mm end at the closest it can focus, of say something standard like a coin, stamp, lego man etc?

looking at how close one can get with lens, and perhaps other qualities such as Bokeh etc.

any samples much appreciated.

No pics but the spec says 0.29X assuming you are using an APS-C camera the frame will be filled with an area about 76mm wide, try a ruler to get an idea.

This might be of some help. We all know how big a CF card is.

@cdiphoto - yeah, that pretty much shows it. Was it on a crop camera? Thanks for the posting. It seems to get pretty close.

[cdifoto]

Yeah as indicated, this is on a 10D. It wouldn't be quite as tight on a FF or 1.3x camera.

This is a pretty small metal ring. Pretty sure it was close to maximum magnification.

here's a small ninja panda, it's about 1.5 inches tall.

'love that wee ninja panda. Looks like he's training for boxing Tetris pieces.
This 24-70mm f2.8 lens seems to cope with the kind of Macro I'd be using it for...
Thanks for all the examples..

these were taken before I sold the lens. Used it a handful of time while in Nicaragua. Though nowhere near the performance of a dedicated macro and ring flash, this performed really well in a pinch. We wanted to exemplify how badly the poor need dental care in Nicaragua. The intraoral shot shows the root was broken down for so long that the body naturally started to exfoliate it.

This shot shows teeth that were only in the mouth for 2 years, and it's a shame the 8 year old who needed them out could have avoided this if access to dental care were more abundant.

Thank you for SPOILING my evening... And excuse me, but what does this has to do with the OP's question?

[drPheta]

Show's about as much macro as I could get with the 24-70 in those conditions (intraoral and extraoral). The OP asked for lego men, but many macro shooters do shoot clinical photos. I'm trying to show that it can work intraorally, though not nearly as good as a dedicated macro lens. I'm just trying to be helpful.

FYI, the lens was about 1.5 feet from the patient in the first photo @ 46mm. The second photo was about the same @ 66mm.

[olz]

The OP also says "standard" things. I belive mouths vary in size... I'm sure you're trying to help, but please understand that such pictures offend people - including me. I'm not as feeble as I might sound, but when I choose to read a thread about the macro capabilities of the 24-70, I didn't expect to see thorn out tooth and gore.

[drPheta]

I have made a link for helpfulness to those interested in macro photo in clinical settings, and a warning for cencorship. My apologies.

[olz]

Thank you! Love the thing you're working on in Nicaragua! Thumbs up, and my apologies for hijacking the thread. Lets get it back on track - I'm considering the 24-70mm f/2.8 Macro myself...

Wow, thats really clean for ISO 800, especially on a 10D.
What noise reduction did you use?

Proper exposure. :)

Seriously though...proper exposure and DPP's Chrominance NR. Chrominance is where the 10D falls on its face. Get rid of the color noise and you're golden. Same goes for the 1D II.

Plus it's only a 1024px image. :lol:

Here's a shot I got the other day trying to figure out the same thing. I think it works pretty well if things will stand still for a second.

ok, thanks for that posting. Is this a small crop of the original?

[Phrogdriver]

Here is the original...now looking at it again..not sure about the crop. But, this should give you a good idea.

[lowcrust]

Couldn't you stack a few extension tubes on it and get some really good magnification. Would only cost you a hundred bucks or less for a set.

[Sfordphoto]

Dang, I was looking for examples like these too. Thanks

[Phrogdriver]

I'm glad these helped. I'm just getting started myself, so I know how helpful all these things were for me. The extension tube thing...well, I think they would soften the image too much..but, then again. I don't really know. I find a nice sharp image cropped looks better than a softer zoom.

[lowcrust]

How would they soften the image?

[gospastic]

this was taken with tubes and the 24-70, and it's very sharp. only problem is the DOF is razor thin. clickable for larger version:

"Stamen" and "Violet" on this page were shot with the 24-70 on a 5D with extension tubes.

Thanks for the posts...I guess there isn't any softness that I was afraid of. Maybe the DOF gave me that impression. I have never used those personally, just from what I have seen on posts like these. Thanks.
