Hi guys, I'm thinking of getting a new lens but not sure whether I should spend more to get a f2.8 rather than f4. I intend to take more of portraits for that lens. Should I spend more to get the 2.8? What benefits do I have over the f4?

Quite frankly, if you want to get better bokeh, go for a prime with >f2. You will be much happier with the quality of the photos.

Generally, an F2.8 lens will be bigger, heavier and more pricy than an F4 lens. Apart from shallower DOF, an F2.8 lens will provide a brighter view finder which will allow both the photographer and camera to see better and thus, take better photos. To me, this is the most important advantage.
Then you probably got a bad prime lens. :bsmilie:
The f/2.8 lens gives you the flexibility to use f/2.8 when the situation arises.
Also, the f/2.8 lenses are usually built to be tougher, for heavier usage. For example an 18-55 f/3.5-5.6 kit lens vs a 17-55 f/2.8
You pay significantly more, though you do get what you pay for.
No. It seems you don't know what bokeh is. Prime lens does not mean good bokeh.
and you are the only one who knows, is it?

Lets see if I get it correct, bokeh is not determine by whether you are using a prime lens or a zoom lens... neither was it determine by whether your lens has variable aperture or fix value aperture. It is determine by the design of the aperture blades, the number of the aperture blades.
Prime lens are generally sharper, due not because it is prime or not, but because there are less optics in the lens, and also the control during manufacturing of these lens is easier, also it had less moving parts too... but that had absolutely no effect on the bokeh.
Nope, it's very common knowledge, well-documented in many sites across the web and is easily researched, and anyone who tries to talk about bokeh should at least know what it really means.
Just because you don't know what it is, does not mean you need to try to defend yourself with aggression. Try to learn a bit instead.
