What type of lens do I need?

My camera is a Olympus OM-D Mark 10 II.

I need a lens that will take a life size full length portrait that will be used for a reference photo for an oil painting.

I’m having trouble understanding lenses. The photo has to be clear and sharp. I have an Olympus Digital 14-42mm 1:3.5-5.6 IIR MSC.

I also just purchased an Olympus Digital 45 mm 1:1.8 and it also has 0.5/1.64ft -~ It’s a Portrait lens  called Prime and doesn’t move. It works OK for above the waist and the photo is clear enough to do a painting with a life-size face.

I understand to avoid wide angles because they would force me to move too close to the subject and will cause distortions. Telephoto lenses would be more useful.

I will be using a tripod and I will be using camera raw. Also, I understand I need to be eye level and at least 15 feet back. I understand at life-size, I will have a foreshortening problem that Photoshop could correct.  

What is the best lens for me?

    Save yourself some cash. Use the lenses you own. Take a waist to head shot,then a waist to floor shot, using your tripod platform elevator. Then stitch together in photoshop.

    Build a high resolution, pin sharp, mosaic of any image.

  • Your camera has a micro 4/3 sensor measuring 17.3mm x 13mm. If you make a viewfinder out of a piece of cardboard or paper that has an opening of that exact size, you can use it to frame your subject and at the desired composition and subject distance, the card distance from your eye will be the focal length distance you'll need to frame the camera image to the same composition with that sensor (or film) size at that subject distance. For example, if your viewfinder ends up 45mm from your eye when you have the subject framed as you desire, you need a 45mm focal length lens for that composition at that subject-to-camera distance. If it was 65mm from your eye, you would need a 65mm lens, etc. This obviously works better with larger cameras, but it is one way to figure it out with any camera.
