Sony DSC-HX20V vs. Sony DSC-HX200V
Well it all really depends on your need. Just think over how you'll be using the camera and then decide whether you need a compact HX20V or the HX200V with better zoom and features like a tillable screen and an electronic viewfinder.
I really don't feel that theres any difference between the HX20V's and the HX200V's photo quality. But other things do matter for example grip, etc
Here's something sourced from http://www.photographyblog.com that may help :
In not being a fashion conscious pocket snapshot - despite being the flagship unit of Sony’s High Performance compact series - the HX200V, which also incorporates built-in GPS, has its shooting advantages; chiefly the grip is larger - large enough to squeeze three fingers comfortably around - the camera, when loaded with rechargeable battery and SD or Memory Stick Pro Duo card, is heavier, plus both these features help provide a steadier hold when shooting towards the telephoto end of the zoom. To further help prevent blurred shots in such circumstances and in low light, Sony has also provided optical ‘SteadyShot’ image stabilization.
The build and finish here is of high quality, with the all-black matt finish to the body and various DSLR-like dials and controls - not to mention both angle adjustable LCD and built in electronic viewfinder - on initial inspection lending it an impression of being a ‘serious’ enthusiasts’ model. While, as we’ll discover, there might be some features missing in that department, overall we prefer the look and feel of the HX200V to the same manufacturer’s entry level Alpha DSLRs; it’s less obviously plastic-y. The compact size also means that locating the right control is never a stretch for forefinger or thumb. Most of the features you want to access are literally at your fingertip, which of course makes for speedier overall operation. The only stumbling block may be, cough, the price. A price of £479 via Sony’s online store at the time of writing is the equal of an entry level amateur digital SLR and kit lens, if admittedly one with far less scope when it comes to available focal range. Overall dimensions are 121.6x86.6x93.3mm and the HX200V weighs a starter DSLR-like 531g.
The front of the Sony Cyber-shot DSC-HX200V is dominated by the Carl Zeiss Vario-Sonnar lens, here boasting a maximum aperture of f/2.8 and a focal range the equivalent of a wide angle (but not ‘ultra’ wide) 27mm to 810mm in 35mm film terms - suggesting serious ‘poke’ at the telephoto end and real suitability for those paparazzi style candid portraits at full zoom, as well as of course landscapes and group portraits at the wider end. The lens does offer the advantage of built-in anti shake and its maker claims this model features a refined gyro sensor - presumably, we hope, thereby making it more effective.
We also get an AF assist/self time lamp porthole top left of the lens - when viewing the camera front on. The barrel itself features a lens ring, which will hold real appeal for photographers who prefer to get hands on, as this not only controls the zoom - if you don’t want to use the compact camera-style lever that alternatively encircles the shutter release button - but can also be used to focus if flicking the switch at the side of the lens to ‘MF’ mode. So manual focusing and manual zooming on a consumer level ‘super zoom’ camera, that is less physically bulky than say Fuji’s Finepix HS20 and HS30 models (also 30x); that’s not to say it’s wholeheartedly better of course - for us the Fuji still has the edge for more precise manual focusing. On the Sony the zoom action is still motor driven, however you handle it.
