As for digital SLR photography …….?
Nikon now say "The Nikon D300 is a semi no, if a professional DSLR it completely? Although not really a patch on the D3, in my opinion, but to say that the Nikon D300 is good at least 150,000, shutter release, now correct me if I'm wrong but when I owned a Nikon F3 with MD4 motor drive, i knocked out about 500 boxes per week as a professional, including the frames of the test. So How I see it, that probably amounts to about 25,000 frames per year, so that the shutter nikon saying only good for about 6 years? or I'm reading bad ……. thanks guys. Thanks for the answer to my waphel: but the D300 as it has been superseded by the D3, so unless you want to move up, and pay extra large pair of full-frame D3, I'm afraid your stuck, but this is somewhat ironic, Nikon do not give a lifetime permanent sealing of the D3, or I miss him.
Japanese manufacturers always contacted each of the parties in relation to another specialist, so that white space coming lens Hoya, finished polished and coated lenses from Pentax, the sensors come from Sony or Nikon for your (and my Pentax) Samsung, pentaprisms come from Pentax, Samsung digital memory (Or one of its susideries in Korea) and the trigger mechanism will come from Seiko. This has obvious benefits for manufacturers because they have no R & D costs of these items, but does not mean that all Japanese cameras have very similar performance, the only difference between any of them is the quality of construction, the A / D converters D, menus and the 'ethos' of the Company regarding such things as camera RAW conversion to JPEG, etc. Do not get me wrong, I think this is a good idea as Seiko, for example, has a worldwide reputation for unsurpassed timing mechanisms, and we, as users of the camera to obtain the benefits of all its wealth of expertise. But when you hear people discussing the draw between a trigger for Canon and other manufacturers that make me smile, because it probably the same exact unit. I noticed lots of film and digital SLR and medium format cameras have never found anything other than a Seiko shutter any of them since the mid 1970, Hasselblad and Leica, even now have them. Those who worked on Seiko were not marked, but a quick search on the number of the FCC on Seiko revealed as the manufacturer. The only thing to go wrong with these modules is the second curtain 'trigger' the older ones were wearing stainless steel, titanium are presently (Same material as the blades of the shutter) that wear very little. The figure of 150,000 is quoted Seiko own and is actually a worst case scenario, add 50% Waiting for an average and double that for a more "normal" figure, if there is such a thing. Chris
