    Bridge/dSLR sensors

    Hi, Is there anyone who can tell me why bridge cameras do not have the larger sensors that dSLR cameras have?
    If they did, surely the result would be a camera with the quality of a dSLR with the ease of use of a Bridge.(no lens changes at inconvenient moments in the field)
    I find this an interesting topic and would appreciate your views on this.
    I look forward to hearing from you.
    Cheers, Rod.

    Hi Roderick,

    My guess would be that:
    1. A larger sensor == larger camera.
    2. A larger sensor == larger price tag.
    Either or both may put off the targeted consumer of bridge cameras.

    As well as the points George raised there is the natural evolution of technology and, probably more importantly, the need to maximize the revenue stream by persuading customers that each incremental step forward is worth parting with their hard-earned cash for, or am I just an old cynic.

    Hi Roderick

    I think the key factor is the size, complexity and cost of the lens. A smaller sensor requires a smaller lens (in terms of focal length and physical size). There is a good article on this topic on this website (Tutorials) :-

    Maybe

    but it doesn't mean you're wrong

    Another reason bridge cameras are popular is their lens zoom range, anyting form 10x to 20x.
    With a bigger sensor, that would have to be huge and heavy. Given that most DSLR fitting super zoom lenses are at best about 11x and those are bad enough weight and quality wise, to have one even bigger permanently fitted just wouldn't make commercial sense.

    That's why we have the likes of Sony's NEX range, noticed how the 18-55mm kit lens looks overkill on the 'compact' body?

    Re: Bridge/dSLR sensors

    Hi, Thanks to all your replies I realise now that I have greatly underestimated the complications involved in lens/sensor matching.
    It is now obvious to me that the lens system is the most complicated, and possibly the most important part of the camera.
    I wonder if lens developement will advance sufficiently in the future to allow the type of sensor/lens arrangement for which I dream!
    I appreciate your input.
    Thanks, Rod.

    I understand that Samsung and one other (maybe Sony) are making bridge cameras with 1.5x crop sensors - so they are coming.

    Thanks, will check it out.
    Everything advances so fast nowadays it's hard to keep up - and expensive !
