Well, must say nice and interesting thread.. So, gentleman, i am not a professional or i won't regard myself as an amateur either but i am always interested in photography. I bought one Canon xsi 450D, last year because of my passion and started taking some pics too but eventually i started hating the camera not because it's bad or somthing, it coz i am still paying the credit card payment from which i bought that camera for. But since now, new models are in the market, so i am thinking about swapping if possible. Do you think any manufacturer will swap the phone if we are ready to pay the dedcuctable amount of the new camera.. Any help would be greatly appreciated.. Thanks guys...
