We're looking at the following over a 350D:
- Full frame sensor
- Full-pro camera
- Weather sealed body (Not all Ls and EF lenses are weather sealed. Take note)
- High fps
- Built-in grip, larger body with better support (some ppl swear by these and some ppl swear on it cos of the friggin' WEIGHT!)
It all depends on whether u want all these features or not. Whilst I personally lust for a 1-series (even after my switch), I jolly well can't afford those features without any blood-letting on my part. So, it remains there on the shelf till I strike Toto 1 day.
So, do u
need those over ur 350D? U have to ask urself this question.
