I think that the limiteds should have been used at f4 rather than f6.3 as this would have given a similar DOF as the DA16-45 and thus better bokeh. I would not read too much into the bokeh of the limited's in this instance.

Same flower, 3 lenses, your comments.

Have the 43 & 77 ... Waiting for the 31. Eventually I'll sell the 43 as I have a FA 50/1.4 as well.
Best
TOPS.
There is no correct answer.
You like what you like and that's it. It was simply one flower taken with 3 different lenses just to show they were different. I possibly should have used a narrower DOF, ie an aperture of f4, to make the bokeh on the last 2 better.Quite possibly, but it also may have been the lens differences and slight exposure and post process variations.

I think it is the bokeh of the DA16-45 which helps it quite a bit in this particular shot. I used f6.3 which gave it a DOF of about 9mm whereas the DOF of the 31 and 77 at f6.3 is about 22mm and thus has affected the bokeh of those lenses. I should have used an aperture of f4 with the 77 and 31 to reduce the DOF to and make the bokeh better and at least on par with the DA16-45.
The DA16-45 is an excellent performer.
No problem, thank you for your input Gareth.

Yes, I should have used an aperture of about f4 with the limited's so that their respective bokeh would be similar to that of the DA16-45. This is due to the reduced DOF of the DA16-45 as it was at a much closer focus distance and thus resulted in a better bokeh.

Most definitely and I am still learning how best to use my lenses also. In this particular instance I used too small an aperture, f6.3 instead of f4 on the limited's which affected the bokeh. If I had used f4 I would have achieved a much more pleasing bokeh similar to the DA16-45. I used the same aperture of f6.3 for all 3 lenses when I should have used a larger aperture of f4 for the limited's as I was shooting futher away and the DOF was greater. This affected bokeh to it's detriment.
I do not have or ever used the FA20-35 f4, but many on the forum have attested to it's excellent image quality and this would be due to the fact that it is only a 1.75x zoom. If you have a look at the most of the top image quality zooms they are in the order of 2.5x or less. This puts less demand on the lens and thus results in excellent image quality. It is no coincidence that the FA*28-70 and FA*80-200 etc are only 2.5x zooms and the DA16-45 is a 2.8x zoom. Still, the DA16-45 is an excellent performer and would quite possibly be as good as the 20-35 in that particular part of it's zoom range.

... depth of field. Because of the minimum focusing distance of the Limiteds you can't get close enough for higher magnification and therefor DOF brings the background more towards focused. With the awkward given subject matter this isn't so good for the OOO effect...
