lmao. i agree, just in the act of manual focusing one tends to take more time in composing and thinking about the image. not all the time, just more than not, from my observations. i can udnerstand perfectly how the "zeiss" name in the lens makes you feel like you have to be up to its standard. sounds silly but i can see how it makes you slow down. same thing happens to me, only with my medium format stuff, i know shoot my 1d3 like a p&s to be honest, and thats if i shoot it at all.
sure, zeiss is overpriced to an extent, but hold a good zeiss prime in one hand and a 50L in the other, and then use both. even without looking at the resulting images im sure most would enjoy the zeiss more. is it worth the cost? probably not. photography is not only about the finished product, its about the journey to get there, which is why i think everyone who hasnt shot film should get a good rangefinder, shoot a roll of b&w, process it themselves, and make just one print. that alone will make you a better photog than 6 months of digi shooting IMO. my 2 cents
