Everyone is still missing the point. Anything below 50mm is bad for portraits. On the D3100, which is a DX crop sensor, you need an 85mm DX lens. Any photography book will tell you 85mm is the ideal portrait lens. If you put a Nikon prime lens on the 3100 you are putting a full frame lens on a crop sensor camera, which introduces all kinds of variations. I bought a prime 50mm FX lens full frame lens for my 3200 because it was "quoted to be a great portrait lens on a DX camera giving an effective 70mm." and found that was not entirely true. I saw a video comparing a true 70mm DX lens with the 50mm FX lens and the field of view was different.

You're the one missing the point. The consensus has been that the 40mm was not appropriate for portraits. Jessica will find her best (optimal for her) focal length by continuing to practice with her zooms.

Maybe you should watch the short video suggested earlier by mdorn:

No your missing the point your 85mm on a dx is 127 mm its ok , but i used a
85 mm for portraits on a 35mm fx film camera , which would be around 58 on
a dx . That would be 87mm which is a good portrait lens . Or a 105 ff Which is a 70 mm on dx

There talking about 85 mm on a full frame not on a dx , it is a great portrait lens on a ff but you put that on a dx and your into 127.5 mm on a dx the face will not look as normal as it should

I don't see what that video even has to do about portrait lenses. I rest my case!

You sound confused. I don't have an 85 mm lens. I have a 50mm FX lens on a DX camera which is "like" a 70mm DX lens. The point I was making is that 85mm is the best lens for portraits, just be careful that your DX's and FX's match.

I am getting my information from "Photography, Art and Technique" by Alfred Blaker, page 355: "If you use a normal or wide angle lens and move in close enough to fill the viewfinder with the persons's head and shoulders, the nearer parts-perhaps the nose, or one ear-will appear disproportionately large." I think some people here would rather argue aimlessly rather than discuss facts.

That part I totally agree with!

Your previous post about variations using an FX lens on a DX body?
No. I do it all the time.

A 50mm lens on a DX camera (3100) give about the same angle of view as a 75mm lens on a full frame camera. A few degrees difference won't matter. The angle of view of both options gets you the sane distance away from the subject, which is the biggest factor in distortion.

And I want to apologize for my post late last night.
Sleep deprivation and pain meds don't make for a very clear mind.

It's obvious, some of you did not checkout my link to another thread about this very topic (not the cheezburger link). If anyone makes it over there, checkout PalePictures portrait work with a 24mm lens. Furthermore, this also confirms MT Shooter's comment in another thread:

"The biggest problem with people with "knowledge" is that many of them really have very little and simply quote internet postings, many of which are incomplete and even totally false, yet they feel the need to voice their opinions and display their ignorance."

Not my words, but his. I'm sure he won't mind if I quote him. If you care to join that discussion, it's located here:

Goofy - No apology needed. It might be better to read this thread while under the influence of pain meds---I'll have to try it. :-)

I've been doing some research and asking lots of questions with and getting lots of responses on here. I decided to upgrade my lens instead of purchasing a new camera. I went to Best Buy and read about the different lenses. I compared the 35mm, 50mm and 40mm for Nikon. I ended up buying the 40mm because the summary was closer to meet my needs. Got home and tried it out, and most of the photos were horrible. I know I need some more practice with it, but I'm thinking it might not be for me. I'm using it on a Nikon 3100, I don't know if that is making the difference. Does anyone have any advice? I'm thinking about exchanging it for the 35mm

My personal choice for 35mm candids and headshot portraits was always the 75mm to 105mm nikkor. These focal lengths seemed to me to deliver the most pleasing facial proportions, particularly when shooting full-face straight-on, and gave me more control over the background when using ASA 100 film. This interpolates to a 50-55mm lens when used with a cropped-sensor DSLR like Nikon or Canon with 100 ISO selected (I think).

Try it. You might like it... :thumbup:
