Chappers said:For portraits you don't want a lens with to short a focal length. I assume you have the kit lens that cam with your camera. This I think is the 18-55mm. This lens at the 55mm setting will be a fairly good portrait setting. See if this works OK for you. If it does then fine.
If you want something a bit longer then I would suggest you look at some thing around 85mm. However first I would try the existing kit lens and see how it performs. What you don't want is to have distorted features. It's usually the nose that suffers looking bigger than it is in relation to other features. By using a lens of a longer focal length enables you to be further away from the subject reducing or eliminating this unwanted effect.
You can see the effect exaggerated if you take a portrait shot with your kit lens at say set to 25mm and then at 55mm. This is an extreme but it will give you an idea of the problem you are trying to overcome
tezmed said:the 75 to 300 lens is more for zooming in at distance..... for your budget i'd try and get a 50mm lens (£100 in shops ish/ cheaper on ebay/amazon).... and with spare money invest in a light reflecting disc or diffuser, as that can improve photos if used correctly without costing the earth
tezmed said:someone might wanna improve on untechnical answer, but as far as i can make out the 50mm lens is pretty much what the eye can see (viewing angle in shot) so wider than the 50 in the 18mm55mm kit lens... i have both and i use the 50mm lens for portraits (however with this lens you have to move the camera instead of being able to zoom in etc.... as you'd do with the 18mm55mm lens

TCR4x4 said:The 50mm has a wider maximum aperture which is often used in portraiture to blur out the background. Being a prime lens is often a lot sharper than the kit lenses too.
tezmed said:i try a particular style for a month/ or two, then change to something different for a month or two- more to learn about what the camera can do etc etc i just wanna get get a taking photos, for personal use- will take years to become a fully fledged pro lol

TCR4x4 said:Better in some areas yes.
Turnermator21 said:The 50mm f1.8 (nifty fifty) will be by far the best choice for you. A nice focal length and a lens that will really blur out the background to create excellent bokeh. Make sure ur cam is set to aperture priority mode and set it to f1.8. Happy snapping!
