What is the actual minimum focusing distance of this lens? In the technical specs it says 4 inches, but elsewhere it says you can get within 1 inch.

Not sure why it says 4 inches. I can get it to focus at less than one inch. It's a great 30mm lens for macro photography.

This lens can focus down to about 3/4" from the end of the lens, a distance that makes the distance between the subject and the sensor inside the camera about 4 inches. In practical use, one must get very close to their subject to get the maximum magnification, which for some might make this lens impractical. I use this lens not only for macro use, but as the standard lens which stays on my camera most of the time, it does very well in all situations and it is very sharp.

i've found 1 1/2" is the "best". That close, always manual focus if possible.

I believe the specs are correct - the lens will focus about 4 inches from the sensor plane (marked on the top right of the body) That's right about the front surface of the lens, which may be the reference. I have a 1A filter on mine, and the lens will go a little blurry if my subject is on the lens, but ease back just a bit and in it comes.

I have actually taken a very successful picture of my fingerprint at 1 inch. I guess it might make a difference as to the actual detail of what you are taking a picture of. The more complicated, the closer you need to be..........happy snapping

Hi, The focusing distance is always measured from the sensor. Therefore, subtract the distance from the sensor to the front of the lens barrel (approximately 3 inches), and you are left with actual "working distance" of about an inch. Hope that helps.

I think that refers to the macro feature. True macro would be 1:1 meaning a one inch object would be one inch on the sensor/film. So this lens would have a one inch object being .36 inches on the sensor. Which is quite good given the sensor size. The zoom is as rated (12-50 with a 2x crop)

This is the most easiest lens I have ever used....because you will almost never have to adjust focus, just keep it around 4-5.6....every thing will be in focus. Its quite sharp.

What I do remember is this: it is a 5 diopter lens which has a focal point of 3"-5" with a magnification of 1:2.25. So far this has worked well for me.

At full, 42X zoom (1,000mm), the focus distance is about 8'. But I find that if I take the zoom down just a little to 39x (928mm), I can get significantly closer. Maybe 4 or 5 feet. This may give you better results at a distance. Also, at long zoom, it is harder for the autofocus system to focus. Bright light is required.

This lens does not zoom in, it is a fixed focal length. You can get pretty close to your subject with this lens but it's not adjustable.

According to the information with the lens, the minimum focusing distance is 0.39 m or 15.4".

for close ups it is ideal. 25-40 Feet will be fine but for further distances you might get the subject, but it will not be close enough to focus.....For portraits it is an ideal lens, and any immediate close ups up to 15-20 Feet.

I use mine on a Tamron 18-80 lens. The autofocus works fine until it reaches the 4.5 focal length, as stated on the product description, this is around 55 mm, on my lens. anything higher than that I have to switch to manual Focus. I am very happy with the results I am getting while using it...

Closest usable focus distance is about 5.5 inches from the lens. What that means in practice is that an item one-half of an inch across will fill about half the frame (at least on my 50D).

2nd answer. If you mean the closest distance you're able to focus at? I can only guess at about 15 to 20 feet. If you mean the closest distance you can calculate by using the mildot system I would again guess as close as you can get a clear focused picture. Mine gives me a very clear picture fifty yards and out but I could not honestly tell you the minimum useful distance.KT

The lens is about 5 inches in diameter. I actually bought this for my mother, who crochets and does needlework. She loves it and has no complaints about it.

I did not accurately measure this but from my observation using the unit minimum distance that it will focus is about 8-10 feet. It will not focus closer than that.

It really depends on the focal length of your lens. What type of lens do you have?

That is exactly why I purchased this lens and I love it! The focus is a bit soft if you try and go below f2.2, but as I'm generally shooting moving children I usually keep it around f2.5 or 2.8 anyway. 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
