50mm Focal length for portrait
« on: November 02, 2011, 02:40:03 AM »
Can good portraits be taken at 50mm (eq) ? I use a rebel and find that for head and shoulder shots taken at about 4 feet away from the subject, 35mm seems nice. (35 x 1.6 = 56)

Does this contradict the long standing notion that you need a 100mm (eq) for a good portrait ?

Never heard of this, but I've read that the geometric perspective of 43 mm FF is similar to that of the human eye. However, I find it boring to see in photos the same perspective as the eye, so it depends on what you like.

I use 50mm for portrait all the time on a FF and I love it.  I also have the 85mm for tighter shots but my 50mm is almost always on my cameras.  I find very versatile, so dont hesitate to use it.

I think either of this can work. And there are indeed different notions about this question. You will find people who will tell you that 100mm is already too tight and flattens out facial features too much. I don't find that to be true necessarily and like using 135 or 200mm lenses for this - especially outside and with kids.

Assuming here that you have a "crop" camera the 50 will actually give you the equivalent of about 85mm which is also considered a (if not THE) standard focal length for portraits.

But then again I also like fast 50mm lenses for portraits (on full frame) so your 35mm may work well for you as well.

When using a zoom I find myself ending up in the 70mm vicinity a lot - especially inside and when using a neutral background.

It's all good.

It depends on your definition of a portrait - the picture given does not fit the normal definition of a "portrait"; it is an OK picture but not a portrait

85mm to 135mm is the traditional focal length for portraits on full frame.  This would translate to about 50mm to 85mm with a 1.6 crop camera.

So, 50mm is close to the traditional portrait range for your Rebel.

Of course, you can use any focal length that produces results you like.  Some even use ultra wide, while others feel that 300mm flatters the face by shrinking the features.

If you are pleasing yourself use what you like.  If you are trying to produce a flattering portrait to give or sell to someone, stick with a traditional focal length unless you have a specific request.

One taken on the weekend at a halloween party, using a Samyang 35/1.4 on a 7D, so about 56mm.
I was about 2-3m away, live-view MF held about chest-high, slightly cropped (about 80% of original area).
The lower focal length was useful as otherwise I would have had to step back into the garden, and it also kept DOF a bit longer than normal, manual focussing that quickly in that low-light isn't too easy, and I needed a margin-of-error for movement on the widest-aperture available.
Too much gear, too little space.

My definition is a picture of one person, doesn't have to be head-only or head+shoulders. Full-body and 'environmental' portraits are still portraits in my books. But that's just me, anyone have other definitions?

I agree, that first image meets the definition of a portrait.  The second one is not, because there is no face or expression, its a snapshot.

Here is a commonly accepted definition from wikipedia, andthe image of the young boy certainly certainly qualifies.

A portrait is a painting, photograph, sculpture, or other artistic representation of a person, in which the face and its expression is predominant. The intent is to display the likeness, personality, and even the mood of the person. For this reason, in photography a portrait is generally not a snapshot, but a composed image of a person in a still position. A portrait often shows a person looking directly at the painter or photographer, in order to most successfully engage the subject with the viewer.

This article might be of interest.  Comparative shots at different focal lengths.

Thanks April - its nice to get a compliment. The picture is my 9 year old son, taken with a 35mm 1.4L at 1.4 in my living room using daylight. I was sitting in a chair about 4-5 feet from him.

Personally I find the 135F2 best on ff. The quality of the lens is very good, bokeh is excellent and the little extra reach stops distortion. It is also good for dog portraits at about F4

The important thing is the distance between the lens and the subject, combined with the size of the features that you're photographing (usually facial features).

If you try a head only portrait with a 35...50 mm FF, you're likely to increase too much the nose and cheeks. Whereas a focal length beyond 85 mm will force you to keep a distance significant enough to keep away such distortions.

However, if you try half / full body, even 35 mm is perfectly acceptable.
