Hi ckanthon
Re your question:
Quote: Kindly list out all the advantages of buying (or using) Pentax DSLR.
I'm afraid I couldn't possibly begin to "list out all the advantages of buying (or using) a Pentax DSLR", as there are far too many to mention here ! Being a 'died-in-the-wool' film devotee of many years standing, I originally invested in both the Olympus 35mm system (OM1N) & subsequently a Mamiya Medium Format camera (just so you know, the K10D is my first ever Pentax !)
I tentatively decided to 'dip-my-toe' in the digital waters about a decade ago, when Fuji's S602Z 'bridge-camera' was being superceded and it's cost had dropped substantially.
Over the past few years, as the price of many DSLR's have started to become affordable and following a great deal of careful research, I finally chose a Pentax K10D, D BG-2 grip and Tamron 18-250mm super-zoom and later added a Sigma 10-20 HSM wide-zoom and Metz 48 AF-1 flash.
Thus far I have yet to become disenchanted with my purchase (very much the opposite, in fact !) and IMHO, nothing thus far comes remotely close to offering such a feature-laden camera for so little outlay.
I cannot even begin to describe how naturally balanced and ergonomically "right" the Pentax K10D seems in my hands.....it feels so "comfortable" that it's almost as though it's been tailor-made for me, rather like a Saville Row suit ! All the controls fall intuitively to hand and it's build quality is amazingly solid.....it's possibly the motoring equivalent of an Audi ! Incidentally, I've handled both the latest N***n D300 and C***n 40D and neither of these models hold a candle to the K10D in this respect.
The inbody SR (Shake Reduction) feature is an amazing boon for capturing pin-sharp images in ridiculously low-light situations, which I would never even
thought of attempting in the days of slow ISO film speeds. Here's some free advice : Whatever DSLR you eventually decide to purchase, just make sure that it has either Shake Reduction (SR), Image Stabilisation (IS) or Vibration Reduction (VR). It's one of the few genuinely useful inventions, where hand-held photography is concerned ! Oh, I almost forgot to mention the 72 weather-seals on the K10D's body..........handy if you need to keep shooting when it starts to rain (used with Pentax *DA lenses) !
In addition, every single K-mount lens ever manufactured for the past 40 years benefits from this remarkable technology. Just sit down and think SERIOUSLY about the implications of that for a moment ! How much extra are you prepared to shell-out for equivalent lenses with in-built stabilisation circuitry from either C***n or N***n ? HOW MUCH, I hear you say ??.......you sure got THAT bit right !
In fact, if I'd bought either the Tamron 18-250mm or the Sigma 10-20 HSM wide-angle in either C***n or N***n lens-mounts, they WOULDN'T be stabilised at all, because neither company offer image stabilised versions of these respective lenses !
Purchasing a DSLR is a very personal matter and what suits one person might not suit another. I'd simply advise you to visit a decent photographic store and then try handling as many cameras as you can. Don't be swayed by what salespeople might have to say, because they often have hidden agendas and are probably working on commission anyway ! Then (and only then) buy what feels right for YOU, finances notwithstanding. Hope this helps somewhat......
Best regards
Richard
