Devi chiederti se ti serve uno zoom 12X perchè naturalmente la qualità di uno zoom del genere non può essere pari a quello di uno zoom con escursione focale minore. In tal caso opterei per un 3X-5X massimo.
In ogni caso le cose importanti sono 1) la possibilità di scattare in manuale cioè scegliendo liberamente tempo di scatto, apertura di diaframma e ISO, o al massimo almeno di scegliere l'apertura di diaframma e 2) le capacità macro.
Ti riporto il riassunto della recensione di dpreview.com, uno dei siti più affidabili secondo me:
Conclusion - Pros
User-friendly, easy to operate interface/design
PASM shooting modes
Versatile 12X zoom lens
Effective optical image stabilization
Good image quality at low ISO sensitivities
Decent, if not outstanding sharpness across zoom range
Reliable metering/AWB systems in most conditions
Ubiquitous AA batteries will appeal to some consumers
Conclusion - Cons
Relatively sluggish operation especially when using flash
Image quality drops off above ISO 400 as noise levels increase
Sharpness drops off towards frame edges throughout zoom range (and CA is noticeable)
230,000 dot screen isn't as sharp and detailed as we'd like
'Chunky' form factor makes the camera less compact and pocketable than competitors
Battery life from alkaline AAs is disappointingly low (sometimes <100 shots depending on use)
Although not the most slender compact camera out there, the SX150 IS comfortable and easy to use, and its stabilized 12X optical zoom offers impressive versatility coupled with good (for this class) image quality at low ISO sensitivity settings. A well-rounded feature set meets the needs of snapshooters along with those who have (or want to have) more experience with manual controls.
Slow performance and noticeable image noise at mid/higher ISO sensitivity settings are the two major drawbacks to this otherwise appealing camera. Other than fairly responsive face detection and autofocus (in good light), the SX150 IS feels somewhat sluggish. It takes a couple of seconds to start up, and shot-to-shot times aren't great, especially when using flash.
Battery life is bottom-of-the-barrel at around 100 shots using conventional alkaline cells, although there are a number of users who will inevitably prefer the convenience of ubiquitous AA batteries over proprietary rechargeables. Image noise is also an issue, even at ISO 80-200 (if you look close enough at shadows and areas of plain tone). But if you plan to shoot outdoors during the day, you're unlikely to be troubled by it.
Aside from these shortcomings, the camera is capable of delivering some really nice images and comes with enough controls and options for a wide range of shooters to enjoy. The fact that it can currently be found for well under $200 makes it a terrific bargain, too.
Quindi insomma recensione positiva anche se pare sia lenta...ma se intendi scattare foto ad insetti morti non dovrebbe essere un problema...
La foto a cui fai riferimento è molto buona, con che macchina è stata scattata?

fotografare soggetti messi in posa è senza dubbio la priorità, anche se sarebbe bello poter disporre anche di una buona capacità di fotografare insetti in natura. Comunque, per il giudizio che abbiamo letto e per il budget tanto limitato, sembra effettivamente difficile trovare di meglio
