Aperture f/4 vs f/2 vs f1.4
I use my EF 35mm f/1.4L USM to take three shots with different aperture: f/4, f/2, and f/1.4. As you can see, f/4 and f/2 have big difference (in case of bokeh); f/2 and f/1.4 I can see the difference but it’s not too much. When you want to take portrait photo use EF 35mm f/1.4L USM be careful using wide aperture; for example you use aperture 1.4 with far distance with object – the object maybe blur because the focus area is too small. For myself, I seldom to use f/1.4 to take portrait photo because it’s not easy to hit the focus perfectly and you need to set your position in certain distance – otherwise you don’t get the focus area perfectly (because the focus area is too small). Aperture 4 is very safe aperture but remember that bokeh isn’t very good and also shutter speed maybe become slow and you need too increase ISO (in low light condition) otherwise you only get the motion blur. I use f/4 if only I want to take group photo, so I can cover big area. I often to use f/2 to take portrait photo because I still get fast shutter speed and good bokeh (not superb if you compare with f/1.4) – and the most important is you get the larger focus area and better sharpness (compare with f/1.4 because in wide open aperture sharpness usually isn’t very good). Sometimes I also use f/2.8; it’s also nice aperture – but when I use EF 35mm f/1.4L USM, I think f/2 is the optimal aperture compare with f/2.8.
fixed lens…. susah

BTW it isn’t difficult if you often to use it…….of course it will be difficult in use for some limited spaces and conditions.

get this lens and you never regret it… I think it’s good to combine this lens with EF 85mm f/1.2L USM – I like using fixed lens, these 2 lenses are my fave lenses.

How do get the maximum sharpness at 1.4? how do you know the distance required to get the sharpness?

@Karasawa:
A little bit difficult to answer your questions, anyway I try to answer your questions. The answer of your first question actually is your second question ~ you need to know the distance to get the maximum sharpness. You need to have experience with your lens (in this case I use 35mm/1.4L) attached with your camera (in this case I use Kiss Digital X ~ similar with EOS 400D) ~ try to shot the object with different distance (you can mount your camera on tripod and shoot the object, after that try to move the object backward 5cm then shoot again, after that move the object again 5cm and shoot again, stop until you feel I can’t get the sharpness) and you will know the best distance to produce the best sharpness. The other important thing to get the sharpness is the object size and shape, a little bit difficult to explain this but you can try to shoot small object and large object with the same distance.
Honestly when I use EF 35mm/1.4L attached with Kiss Digital X, I seldom to use f/1.4 because the sharpness is not good as f/2. I like to use f/2 to get the optimal sharpness and DOF. You also can see from the photo, f/2 and f/1.4 are not much different in terms of bokeh (I think).
