Photokina, where camera nerds wrestle with wants vs. needs

Canon and Sony launched theirhighly anticipated new dSLRs.

The photoindustry's biggest trade showis where camera makers like to launch their latest wares and this year's Photokina didn't disappoint. Both Canon and Sony unveiledtheir highly anticipated new digital SLRs, the 5D mkIV and Alpha A99II.

Lens companies also bring out the big guns atPhotokina.

Regular picture-taking folks make up the bulk of the camera-buying market, butPhotokinais also where the optically-obsessed showcase their flashiest,niche equipment.

But itwas Fujifilm that stole the show, according to many industry watchers.

The GFX 50S is the Japanese brand's first digital medium-format camera (its newly designed sensor is way bigger than the standard 35-millimetre ones that form the benchmark for most higher end dSLRs), and Fuji promises to sell it for "under $10,000" US. A price tag in that range is, believe it or not, quite a bit more reasonable than othercameras in its class, which is givingFuji some potentially game-changing cach.

Somewhat paradoxicallythere aren't many photos of the latest cameras, but tech site Engadget has a good review of the new Fuji.

The cameramarketplace is crowded with quality.

Manufacturers continue to pushpowerfulmodels on consumers, which makes it hard to pick a lemon when it comes to buying something new. But, asThe Verge reports, several years of high quality releasesmakethe need for upgrading from a good camera that's a few years old to a newer model a much harder sell.

Action cameras are another growing market.
