Is there a big bokeh difference between 60mm f/2.8G micro and 85mm f/3.5 micro?

I have a Nikon D3100 and am planning to buy a new lens, specifically a prime lens. All the photos I take are of food, for my food blog http://fifteenspatulas.com/

My problem with my photos now is that they are not sharp at all.

I've narrowed my choices for a new lens between the Nikon 60mm f/2.8 micro and 85mm f/3.5 micro. I do want to have some bokeh/blur (I know those aren't the same thing but forgive my lack of photography knowledge) but I don't know if 2.8 and 3.5 is a big difference.

I also think maybe the 85mm may be too much zoom for me but that's another issue.

If you have any insight on the differences between the aperture for these lenses (or anything else), I would be grateful to hear it.

Macro lenses are primarily used to shoot close ups where the out of focus background is not that important since the depth of field is so shallow at 1:1 or 1:2 image to subject ratios, the term "Bokeh" is not really relevant.

Here is a discussion of what Bokeh is.

It is my thought that you have only heard about Bokeh and do not know all that much about it. This thought is further supported because you seem to think a 85 mm lens is a "zoom".It is not. Macro lenses are prime lenses a lens with a single focal length. Zoom lenses would be something like a 24-70 mm lens.

To really see what the out of focus area will look like is to visit a proper camera store and look through each lens when set to 1:1 macro ratio and spend some time looking at the out of focus area behind the subject.

Go with the 60mm. You do not need the extra length of the 85mm for anything and in fact, I think it is harder to shoot what you do with the 85mm and the D3100. When you go to focus, make sure that you know how much you want in focus and this you control by your aperture. The smaller the aperture(bigger number), the more in focus. Also, focus 1/3 in. Focus is not equal front to back. To maximize, pick a spot 1/3 into the area that you want in focus. If you want softness, just open up the lens and focus on the piece you want sharp. The 60mm will be a very sharp lens. If you are in focus and do not have motion blurs, you will have nice pictures.
