Can someone in very clear laymans terms explain the difference between these two lens?
Sigma 50-500mm f/4.0-6.3 EX DG HSM for Nikon
and
Sigma 50-500mm f/4.0-6.3 EX APO RF HSM for Nikon

Please? Thanks

One is an EX DG HSM and the other is an EX APO RF HSM.

Sorry, couldn't pass that one up...

Might not notice a difference between the two. Get a monopod if you decide to get one. My last 4 entries was shot with the DG version. Dragon Boat Event was taken with Bigma and 1.4X tele.

Um Monopod what? (very basic laymans terms would be awesome) lol

Your shots are awesome.. love how clear they are..
so the only difference is the purple fringing elimination? Is there a difference in the glass? / quality? still lost

Mono = one, Pod = Mmmmm not sure.... Pretty much a extra leg, atttaches to the funky collar on big lenses so that you can get sharp photos. Not as stable as a tripod (tri = three and i'm still not sure what a pod is) but not as bulky either. I can get pretty sharp photos using my monopod at 1/2 seconds, and 30 seconds with my much cheaper tripod.

From the Merriam-Webster online dictionary:

"Etymology: Greek -podos, from pod-, pous foot
: foot : part resembling a foot <pleopod>"

So, basically, it means a foot in this context. Monopod is one foot, tripod is three feet.

It's a reeeeeaally heavy lens. Actually I was doing curls with them and it seems to be more handholdable.

I use that lens a lot. I rarely use it (twice maybe) on a tripod. The longest session was a 7kilometer trek through a gorge carrying it in my hand the whole way. It took all day...but I did it and got some great images. I have no worries about shooting straight up. I am not a large build, so it can be done.

Some examples -

This other shoot was fast pace. I had 14 - 18 seconds to get 4 shots of each run. Each shot was different focal distance and shutter speed. But I did it....all handheld again.

The Photozone.de Review of this lens for Canon mount explains the difference in the first paragraph.

The Sigma AF 50-500mm f/4-6.3 APO EX DG HSM may be Sigma's most famous lens to date. With a 10x zoom factor and an extreme focal length at the tele end it drew some major attention at the time it was announced. Surely a lens many birders and wildlife photographers have dreamed of. Today it is available in its 2nd incarnation. While the principal design of the 50-500mm EX remained untouched it is now a designated DG ("Digital Grade") lens featuring a new coasting specifically designed for the (shiny) reflection characteristics of today's image sensors.

From that, the APO designated lens appears to be the older version and the newer version is DG.

I'd get the DG.

Hey Judi, here's a question, does Autofocus automatically cut out once the maximum natural aperture goes beyond f/5.6 according to the figure reported from the lens to the camera?

How does it work with regards to aperture and autofocus? Does it report false aperture values?
