Bokeh of 7 Images

I have gathered a few shots with bokeh that I liked.

What do you think?

Fa* 300 f4.5




Voigtlander 125 macro




Fa 77 Ltd




A 50 f1.2




Da* 16-50




Fa* 80-200




DFA 100mm macro




Pentax primes are really great in bokeh production

In terms of Bokeh:
In a first place tie the 77mm 50mm and 100mm but the 100mm is influenced by the nice red berry with an anticipation of the water drop.

Then a second place tie with:

Fa* 80-200, Fa* 300 f4.5, Da* 16-50 and Voigtlander 125 macro

All are great!

Really like the 50mm pic and the 100mm macro pics! They both stand out.
Good work!

You're seriously giving me the LBA bug here, you know? Especially when the 77 and 100 are already on the list...

Great bokeh overall, though I must say the 16-50 looks a little harsh. Might be the business of the background compared to the other images. Great shots.

I'd rate them 77, 50, and 100
then 125, then 80-200
I'm surprised the 300's bokeh looks so weird...

--Cool!--
1. Fa* 80-200 (This probably won't be true on non-green subjects though, given its propensity for axial CA.)
2. A 50 f1.2 (Ditto.)

--Looks good, a little hard to tell though--
3. Voigtlander 125 macro
4. Fa 77 Ltd

--Not too good--
5. Fa* 300 f4.5 (Typical of this lens - and it can work sometimes, just not here.)
6. Da* 16-50 (Blech.)

--Not rated--
DFA 100/2.8 Macro - not enough close to focus (like in the FA* or A50/1.2 shots) that show how it treats the transition. IMO a very close object with a distant background would be rendered pretty nicely by just about any lens, especially a prime.

nice camera bag!! As for the shots, there's something about that 77mm that gives the image a very different look I really like.
Now to rate bokeh
1) 50, 100 tied
2) 77mm
3) 125
4) 80-200 and 300 tied but the 300mm shot is tough for any lens with the highlights
5) 16-50 is a busy shot but zooms have more trouble with this aspect.

Beautiful. IMO:
1st place: FA 77
2nd place: Voigtlander 125 macro
3rd place: A 50 1.2

but it's all hard to judge 'cause I might just be taken away by the beauty of the subjects.
Would have to agree about the FA* 300 - would have expected better, but I'd think it can do...

Liked the shot with the DA* 16-50 - perhaps a comparison with the A 50 1.2 would show off why the 50 is so special...

50 beats the 77 for me personally in this comparison. 100 2nd and 3rd tied for me is the 77 and voightlander. Nice shots all round and i agree.....thanks for inducing LBA

Unfortunately, bokeh is very much dependant on background distance, subject matter and the backgrouds lighting, so it is a little difficult to judge one lens against the other in these examples.

Generally, my FA77 and DAF100 macro have excellent bokeh, which seems to be backed up by your examples here. The A50 f1.2 looks good except for the flowers below the main subject flower. The DA*16-50 is let down by a complicated background which most lenses would have difficulty in producing well. The FA*300 f4.5 is let down by the highlights which seems to affect many lens's bokeh.

To accurately judge bokeh, I would say each lens would need to use similar backgrounds and at different background to subject distances so each lens has a chance to shine.

Just my two cents worth.

yea I agree the FA*300 bokeh is made worse with the bright spots. I guess look on the bright side, there didn't seem to be ring halos on the bokeh circles which could have been more distracting.

I kinda like the shot from the 50mm f/1.2. Bottom line, they are all good. Only have 2 of the lenses in your lineup so looking at your nice pictures is making me drool...

Seriously A 50mm f1.2 is hard to use. But when it works, it stands out. The shallow depth of field is really hard to make the subject even sharp.

As Lance has mentioned, bad me that I picked a busy background. The contrast in the background is quite high - a key property of this lens.

77 seems quite popular and that shot is more like a snapshot when it was taken. Amazing that older lenses stand the test of times...

Sean, thanks for your time commenting. We seem to share similar taste in bokeh. I like Fa* 80-200 bokeh especially on the green background. I like the way it blurrs and the contrast is rather high. This zoom does not do too well on skin tone rendering which is a problem if I bring it to wedding ...

And I can sense your dismay in the criticism of Da* 16-50. This shot is not a good representation of its capability I do not think. I had a problem of accumulating RAW photographs not processing them til next century ...

You are right. Benjikan's key word - closer and closer

That sums up pretty well there.

A 50 f1.2 is a great lens and it balances well on k10d. In an ordinary day, a great lens to walk around with

No, this forum induces LBA. Actually a thread Jonas posted to me today makes me long for Voigtlander 58mm f1.4! The bokeh in the sample shots really fired me up!

Thanks for the time to share the knowledge. The shots are just showing a bit of bokeh, not intended to smear one lens over the other.

You are talking about some sigma telephoto lenses that do that a lot

That was a gift from Jonas. A great lens.

FA 100/2.8 macro

This lens might well be in the league of those you mentioned too...
