Hello all I am looking for a prime lens for my 400d. I have narrowed it down to 2 http://www.amazon.co.uk/dp/B00005K47X/r ... YP75&psc=1or http://www.amazon.co.uk/dp/B0089SWZDU/r ... JE2JCD4K1SIt is mainly for portraits. Question is which do you think is better for the job given the different focal lengths, apertures etc Thank you

I'd go for the 50mm.
It is interesting. When I learnt photography the common wisdom was 90mm or 110mm for portraits.
Good, 50mm is no longer the same as 50mm on a film camera, but it is interesting that the size has come down.

The 50mm. The 40mm is nice, but the 50mm is great. The 85mm on a full frame is great.

James, you could up the focal length and the aperture as well, I have a 120mm f/4 lens that takes beautiful portraits. Of the ones you picked, I'd probably go for the 50mm over the 40mm.

I have ordered the 50mm. Reviews I have read say it gives really good pics for the price.

I've been reading up about this and it boils down to the issue around APS-C and FF. The angle of view is different and you can get differences in things like bokeh. Eg f/2 on that lens would be f/3.2
In the end, it got so confusing. The best advice was just to use what you need eg portraits -use 80mm or 100mm macro.

This lens will give me 80mm on my camera. None of the reviews ever mention the aperture changes. Will see how it goes.

look up 35mm equivalent focal length. Because the sensor on a digital camera is not the same as a 35mm film frame, the amount of cropping on the frame is different. So 50mm on a Nikon APS-C sensor is equivalent to something in the region of 70-75mm on a 35mm film body.

It's a canon so crop factor is 1.6, not nikon's 1.5.
James, from what I recall reading about this, crop factor didn't matter too much. If you wanted the effects of 80mm lens, you used it irrespective of FF/APSC.
I have the plastic-fantastic nifty-fifty and whilst it's great fun, I wonder what the f/1.4 would have been like.

Yeah, I know all that, but your post made no mention of crop sensors. Also, you are misleading when you say "Because the sensor on a digital camera is not the same as a 35mm film frame" because my digital camera has a full-frame sensor, so there's no crop factor involved. There's increasingly more and more full-frame sensor cameras on the market these days. Mark

I must have missed something,Mark... what model have you got now?
Back on topic, I was always told that the 50mm forces you to frame your shots more carefully. Mine certainly did, and I still say it's my favourite lens on the NIkon D90.
