if you use my affiliate code, ws-514, i believe you can also get some free gear with an order over $50

i usually take 2 nikon, full frame bodies. i take my 28-300 lens and take a 16 mm fisheye. love this fisheye, as it is wide enough, and image can be straightened in acr lens correction. it takes great images, it is small and easy to carry.
these are 2 images i recently took with the nikon d750 and the 16 mm f2.8 lens

thanks for posting this. a great site!!

Lens is in very good condition, no signs of wear, I am asking $350

This Sigma lens provides an ultra-wide angle zoom lens from 10-20mm. It can be useful for images of landscapes, large buildings, group photographs or even more. The perspective that changes with the angle-of-view gives picture an extraordinary feeling.the rear lens group to minimize spherical aberration. Minimization of the distortion is a most important issue for zoom lens, but Sigma has succeeded, to provide image quality with minimal distortion by employing aspherical lenses.
Other features include a close focusing distance of 9.4 inches, a non-rotating lens barrel that perfectly suits the petal-shaped lens hood (included), and a one-year warranty.

i have the 750, upgraded from the 700 which i still have and still use often. i love the 750!! it is a great camera, has some nice advantages over the 800. the tilt screen alone is worth it. i use that often with live view and it just makes my photography so much easier....especially if i want to shoot high or low.
24 mg is more than enough. i find the files are large enough, with 36 mg it would be way more.

hope this helps a bit.

i am using ps cs6 for windows, guess i should have been more specific...open a raw file, THEN click on file (top left corner, next to PS), scroll down towards the bottom, click on file info, then click on advanced tab (on the top towards the right)

i hope these instructions and photo help you locate the info.
i am surprised you say you find no pull down for file.

thanks so much!

I did not find any sag nor play: the extension is very solid. Even extended to 71mm, it works well. Yes, it locks firmly on both the lens & the camera.

Thanks so much!!!
I will post another intro for the Savage Macro Art Adjustable Dual Arm LED Light: http://savageuniversal.com/products/macro-photography/macro-art-adjustable-dual-arm-led-light

I use a Nikon D750 camera with a Sigma 105-mm macro lens. To get really close, I used the Macro ART Variable Auto-Extension Tube made by Savage Universal: http://savageuniversal.com/products/macro-photography/macro-art-extension-tube

I have tried extension tubes in the past I never did have any luck with them. I found when trying to use all 3, I could not focus. This extension tube is a one piece, well made, and all metal. It goes from 55-71mm of extension. I used it with my macro lens at a recent indoor Dalia flower show. It was easy to use & easy to focus with the camera on a tripod. I tried both the 55 mm and the 71 mm. I was happy with the results.

The depth of field is shallow, blending into soft focus to the surrounding areas. I was very happy with the results. This was my first time using this variable extension tube.

ISO 250, EV +7, 1/25-sec at f/4, with extension at 55-mm


with extension at 71-mm

i am a nikon user, for macro i use a sigma 105 f2.8 on my nikon full frame camera. i have also used Macro ART Variable Auto-Extension Tube. i was able to get very close up images.
