Portrait lens for Q?

What lens do you recommend for portraits? I don't want a lot of bokeh, but neither distractives backgrounds.
I think the ideal focal lengh it's between 15mm to 25mm (85-135mm).
The 01 prime (8.5mm) looks a little short for this. But maybe I'm wrong.
The 06 zoom (15-45mm) it's great but a no so fast (ƒ16 equivalent) for blow out the background.
There are also many C Mount lenses very fast, but I don't know them.
Q mount lenses I only know the expensive Sonnetar 25mm 1.1. Is there any other like this?

I look at hundreds of photos of Q, but there are very few portraits and most do not have the background out of focus. If you can, upload portraits with the 01 and 06, these are the most interesting for the AF and quality image. Or upload portraits with manual lenses!

I would go with the 06 zoom. It's F2.8, not F16, but you probably still won't get much bokeh. You'll need a DSLR for that

You could also try an adapted lens. There is a thread about the quality of the various adapted lenses on the Q that has some common and some exotic lenses reviewed here in the Q section.

I really don't want a DSLR, but I don't know how much bokeh can get in a portrait with the 06, because I don't find a portrait example, I just see tiny flowers and toys.

Yes, I look the sticky thread about manual lenses and also the thread about photos with Q. But there are very few portraits

He never said it was f/16, he said it was f/16 equivalent. Why is it that almost no one (with some camera experience) fails to understand equivalence for focal length, yet almost no one understands it for aperture?

I generally don't upload pictures of people, and rarely take them. So no examples from me, sorry.

Hi Elvis,

IMO, Getting hung up in image equivalence arguments with the Q is a mistake. It might be somewhat useful in comparing similar formats, but with something as far removed as the Q's sensor format from 135mm format, it's self-defeating. You just won't find glass with the specs that you need to get equivalent images under similar shooting conditions. For portraits, you'll probably want to maintain perspective, so subject to camera distance will be important, and pretty much the same as you'd use with a 135mm DSLR, but subject to background distance will have to be increased, possibly significantly. Then the 06 Zoom will do nicely in the FL range that you specified, I'd think. With a Q system Quality line lens with an internal shutter, you should be able to use flash pretty well if needed.

The short answer is "hardly any". Pretend you're using a 15mm on a DSLR- you basically need to put the subject right in front of the lens in order to get visible bokeh. And you certainly don't want to do that for portraits, as it would introduce a great deal of geometric distortion.

I saw one cool bokeh example with 06 on DPreview forum, i think. Still you need a far away background and can make "face only' portrait.

If you really can't live w/o bokeh but have DSRL-phobia just use BC mode :P

Not sure what you guys are talking about.
As far as i know bokeh is a form of blur characteristics, so are you looking with a lens with much character?

Here's a good bokeh example:
Blossom - Pentax User Photo Gallery

It's at 44mm, though, which would your subject to be really far away

The real issue with bokeh that most people do not understand AT ALL is that while bokeh is often described as better or worse with one lens or another, based upon the hardness or softness of the out of focus circles and how uniformly these are illuminated, there is another mo significant factor.

It is a function greatly of focal length and the impact of the change in perspective / background magnification when you reposition with a different lens to get the same subject size. Long telephotos result in larger out of focus bits in a background than wider lenses where perspective makes the subject large compared to background. As a result, a confused background turns into big blobs of soft color with a tele, or just into an out of focus mass of little blobs with a wide angle. Go long for portrait, the bokeh will be better

Well ... the 06 is better than I thought! I think it's the best option.

Is BC a good filter? Or is the same as using Gaussian Blur in Photoshop?

I call bokeh to the background blur. Much bokeh means much blur. Of course there are different qualities of bokeh, depending on the lens and aperture blades.

I would also go with the 06 Zoom and increase the subject to camera distance, you should get nice out of focus background with tight headshots. The BC I find is fine but I use it on the lowest level just for ait for 'pop' you could get away with level 2 in certain shots but the third level is ridiculous.
I don't shoot RAW that often with the Q I do most of the processing in camera hence I haven't done a Gaussian Blur comparision to see which is best. I like the Q for fast quirky quick to post photos as apposed to my more deliberate photos shot with the DSLR.
