fmian: This is a full frame ultra wide lens. Best to use it on a full frame digital or film camera for the correct perspective. Otherwise what is the point?
You are wrong
victroria: can you please advise me if this lens is compatible with a canon eos rebel xti?
Sure it is, this lens works on both crop and FF sensors the same way
Sebastian Z: After so many months in space, those wheels are so clean...no dust at all, makes you wonder do they have rover washing stations on mars, or that thing just drives in somebody's living room with fake background...
I have spent 2 weeks in Sahara desert, not a drop of moisture, I was one dirty monkey with dust all over, not a clean spot on me after just 2 days... But Mars is different I guess.;)

Isn’t that main goal of many people?, Remove ability to share the news in uncontrollable way? Photojournalists were always on the guard of freedoms, photos are much harder to manipulate than articles, those days it is simply not convenient, so it will get removed...And you can't stop it.
Look how the world has changed, 15 years ago everyone would say these photographers were harassed like no tomorrow. Today everyone congratulates London how polite and Photographer welcoming London is.
Those guys were just taking pictures, and they were all stopped and questioned. Were they threat? Anyone with backpack can be threat but photographers? Why system is so afraid people with cameras, what are they hiding? Don’t tell me they afraid somebody is planning the attack; anyone can use Google maps for that from the camphor of their apartments.
I think somebody is really afraid any one of those photographers could potentially snap something they should not, so they approach the photographer to make sure they have his face recorded from various angles probably taking voice samples as well then doing facial recognition identification and let them go. They can always get them in a matter of few minutes if something should be taken off of their cameras…
