Lens for a good bokeh behind the model

Hi guys,

I am searching for a lens which would be good for outdoors fashion photo. I want the background behind a model to be very blurry. Currently I am using DA 35mm F2.4 which is a great lens, but angle is too wide and the background blur is not enough when taking full height photo.

I expect something like DA 55-300mm would be a good option but I did not manage to find any good examples of a full height photos. Every time I am searching for a bokeh sample photos I see only flowers, dogs or in a best scenario -- portraits. However I want to see a bokeh behind a standing person

Any ideas or suggestions? Maybe 50mm F1.4 or 18-135 or *50-135? Just let me know what you think
Do you guys have a good sample shots using any other lenses with a requested bokeh?

Cheers,

P.S.My budget is limited, but I am not in a hurry, so can be a bit flexible with price.

The 50-135 is a true portrait zoom and at 100-135mm it really isolates the subject. Smooth and buttery blur both in front and in the back of the focus area. Otherwise something like the Samyang 85mm. The Fa 77 is fast but have different characteristic to it than most other lenses.

Standing back just far enough for a full body shot with a 50mm at f2.8 does not get you a very out of focus background on APS-C in my experience. Factors such as how far things are behind the subject come into play, of course. And I can't say what you are expecting but I'm guessing you will need wider than f2.8 on a 50mm or a longer fast lens to really blur that background.

tuco, sure, distance is one of the keys here. I have a lot of space around, so can walk far away from the model and have background starting in some 10m behind her.

The thing is I do not have much options to try out lenses and see what is possible. Thus asking for samples, ideas and opinions

JinDesu, thanks. Your picture shows amount of separation I would like to achieve.

The DA 50mm F1.8, DA* 55mm F1.4 or Sigma 85mm F1.4 would all be great choices.

Yep, the 55/1.4 is really nice too.







The FA 50/1.4 got a similar look to it, though I like the 55/1.4 I got now more.

There is a 50mm at f1.4 and a upper body shot standing close. A good reference. A full body shot standing farther back will bring in that background at f1.4 even more.

You ask for a full body shot and everyone shows you close ups where practically anything will render out of focus when you get close enough.

Don't forget that the blur character (this is what bokeh means) is different with each lens.
So you also need to keep that into consideration.

Just compare the DA*55 with the Sigma 50mm to see what i mean.

Well, I tried hard to find something but had to settle with the pics I posted. At the same magnification the DOF basically about about aperture so the lens with the lowest F-number will win in that regard. So either a full frame camera with a really fast lens or in second the same scenario with a crop camera is the way to go. So basically a F1.2-1.4 lens that is as long as possible to stretch out the background perspective. Backing really far with something like a 85/1.4 or maybe go closer with a 50(55)/1.2 will provide maximum "apparent" blur.

Going all blurred out for a full body shot requires either some kind of crazy equipment, post-processing magic or a long distance to a smooth background. There really is no way around this fact.

Surfing flickr gave me these:

Crop camera and a fast lens: Nikon D2H + Noct-Nikkor 58mm f1.2 AIS



m4/3 and a superfast lens: Olympus E-P2 + Voigtländer 25mm f0.95



Full frame with a super-fast lens: Leica M Monochrom + Leica M Noctilux 50mm F0,95 ASPH



Full frame with a super-fast lens: Leica M6 Classic + Leica Noctilux 50mm F0.95



To get anything more that this would require something like a brenizer stitch.

I would go with the DA* 50-135 f/2.8 as well. Really nice lens with a very useful portrait zoom range. Here is a photo I took of my nephew. Little man on his own isn't full body sized....but with the bag on his head he is Either way, you can see the gradient of the OOF areas from foreground to background. This was shot on my K5 with a focal length of 65mm @ f/3.5. If you would back up, zoom in, and open it up you should get even better bokeh.
