My little bokeh test

[Blake.Oney]

I was trying to get the bokeh to be round. It was actually pretty hard to find the range. I was moving back and forth to get the size I wanted and anything above F2 on my 50mm f1.8 was starting to go octagonal. The first thing I tried was f1.8 and it was totally cats eye, so I went to f3.2 and it was like the UFC. So f2 made a pretty good circular bokeh.

Edit: Updated with all my tested apertures.

f1.8

f2

f2.8

f3.5

f4

f5.6

I shot in Jpeg basic and uploaded over half of them before I even noticed they were sideways. There's no actual subject, though so it doesn't really matter. There's the example of bokeh at different f stops with the nikkor 50mm f1.8D. I was 13 feet away from the lights. I started completely opposite of infinity and focused in just a little bit to make the initial dots smaller. Didn't change it after the first shot. They get smaller as the aperture does.

well alright.

I don't know about anyone else but I think it's a nice looking image. Do not confuse this with C&C.

Why you are showing, why not show us the other f/stop results?

 

[NikonNewbie]

Looks cool Blake!

 

[GooniesNeverSayDie11]

The number of blades plays a part as well I believe. I know the nikon 50mm 1.8 has 7 blades. Canons 1.8 only has 5.

Blake ur bokeh is nicer than my bokeh!

Updated with different apertures and explanation of the setup.

What a jump from f2 to f2.8

 

[Blake.Oney]

There wasn't a whole whole lot of difference in between and I was trying to stay close to full stops, unless it made a huge difference. That is the point where they really started to have pronounced sides. The only reason I put f1.8 there is because that is wide open for that lens.

 

[Bitter Jeweler]

No, i mean how it goes from decently round to decidedly polygonal from 2 to 2.8

 

[Blake.Oney]

Ahhh I got you. I thought you were asking me why I made the jump. Yea I was kind of surprised by that too. The 3rd stops in between started to have sides, but not like that.

 

[Geaux]

Ok, to achieve this ... do you manually focus until nothing is in focus?

With Christmas coming up, would be cool to learn.

I thought the brokeh was very round looking at 1.8, even more so than 2.0... But I was really surprised to see how polygonal the brokeh got at 2.8. Cool test Blake, thanks! :thumbup:
