Really it all comes down to what we have discussed many times before in this, our UHH forum, are DSLR on their way out, how good are P&S, what has been your personal experience, what criteria do we use to chose....etc.
Personally the only reason I have two DSLR is to make me look professional when shooting weddings etc.. that bulk and the extra long heavy lens sets me apart from Uncle Joe and his new mistress Louise. For practical purposes of display, 8x10s, 52" TV, Cell Phone, 7" desk electronic frame, the superbness of DSLR huge files and quality is an excess, the camera a burden. Ouch, what a disgusting, tho true, statement. Next to add to the disgust of most I will say that with out close comparison the unaided public can not tell a difference between an Epson 4 color and an Epson 6+ color printer.... what... heretical!!!
Now coming down to P&S vs DSLR,, P&S are there when you need them, on your belt, in your pocket or purse. Life is of the moment (plus stutter lag :lol: ) and beyond if you use burst mode or even bracket mode. The DSLR on the shelf vs the P&S in your hand... P&S the winner. :thumbup:
$600 for a P&S that has a 3.5 zoom... Big sensor great... but compare that to a super zoom with 20x Leica lens and superb electronics and what is the advantage? crop! to zoom!! humph do the math 3.5 vs 20x... roughly 6x the lens magnification .. that is a lot more surface area, 36 x. Is that right!? Wow!
Excellent night image? Good if you shoot a lot at night - not me. Items needed for the P&S must be defined around one's way of life... their real needs. Weight, hand (grip-ability), quality of image needed, zoom desire (photo a rattle snake give me big x# please), how will your carry it (pocket, belt pack, neck strap, etc.), and hate to mention it $$$$. $600 for that Sony 3.5x vs Panasonic 20x at $225, you evaluate!
Comes down to being real and rational and personalized. The original question said, as I read it, shrink my DSLR and make it a P&S. Question could have stated size maximum, any physical limitations (shaky hand, grip etc.), size of hand, type of shooting usually done, color! (black is safer), .. these things listed first then seek the camera. My gosh, it hard to be rational ... and with so many flavors out there! Well perhaps all those really professional review sites on net are our salvation... aaah and then there is going in to a shop with our SD card in hand and shooting a close and far card target and describing to our selves how the camera feels in our hand.. Tough question isn't it. Care to make a check list... care to automate it?
The devil is in the details vs needs :evil:
