Yes they are!And cell phones aren't easy to break?
They can survive a drop.
They have cases that protect them from big falls.
They have scratch resistant glass
They are thinner than DSLR's and pocket camera
They have neat pouches that clip on the belt
They are more resistant to extreme weather/moisture
They are less heavy/less form factor
Person carrying a mobile phone is a normal thing whilst carrying a big DSLR and/or a bulging pocket camera is a bit of a issue and not a normal thing you see on the road.
And yet, the percentage of cell phone users I know who have irreparably damaged their phones is MUCH higher than the percentage of DSLR owners I know who have irreparably damaged their cameras.
Ofcourse not! DSLR's are much better (I own a D5100, SB-900, P7000 etc). BUT that doesn't mean photo's taken with a good camera phone should be turned down from Nikon and its photo competitions! My photo's prove exactly that!
Did they give you a reason why they rejected your photo?
I have taken some beautiful photos using my galaxy s2 gt-I9100 phone which has a 8Mp backlit Cmos sensor camera. Can I submit those to the competition?
Thank you for your inquiry.
As stated in the "Submission Guideline",
we would ask you to submit your works which is shot by digital still cameras
(including medium and large-format cameras).
*The cameras are not limited to Nikon.
Therefore, we would ask you to refrain from submitting your works
which is shot by mobile phone.
So, this whole thing is just because you're ticked off that Nikon said your camera phone wasn't an "official" digital still camera. It's their contest, their rules. They can include, or exclude, any type of cameras they want to. They may have worded it a bit poorly, but it's still their right to say "yea" or "nay". I'm more surprised that they allow non-Nikon cameras than I am that they *don't* allow cell phone pics. I wouldn't get all twisted up about it--none of the pictures you've posted here were in any danger of winning anyway. They're pretty snapshots, but they are just nothing special and wouldn't have held up against some of the truly spectacular stuff a Nikon photo competition is likely to get.
