    Are you sure about that @StormtrooperStu?
    IIRC, a 50mm APS-C lens on an APS-C camera will be equivalent to 50 x 1.5/1.6 (Nikon vs. Canon APS-C) on a full frame.
    Full frame = 50mm
    APS-C (Nikon) = 75mm
    APS-C (Canon) = 80mm

    Someone please kill this thread, it's giving me a headache.
     
    I think there a couple of people here going around in circles.  :rolleyes:

    I red this as i was going to be last night and it finally makes sense. I thought the entire time that @Myki was correcting me on the crop factor and that putting a 50mm EF mount lens on a crop frame camera would cause it to be a 80mm equivalent. This may be because he had the wrong crop factor and at one point was doing the math wrong possibly. After reading your post it seems he was actually trying to correct me on EF and EF-S lens's being different focal lengths even though they are both for example 50mm. I really dont know why I thought this though because I do know that a lens's focal length is the lens's not the lens's camera.

    Nope no bad blood as i also took it as that and was surprisingly one of the first times I could have something like that on this forum. This is likely because I was wrong for once and I seems now that I was confused one what we were discussing.
    I can actually try that as I have a 40mm EF prime on my camera and that poopy kit lens somewhere around here.

    Not really I kinda just grabbed a good all around prime lens for what I had planned on shooting and started playing with the camera as @The pokemon kid said. I knew a bit about ISO, aperture, and exposure from my canon point and shoot's manual mode. No I usually know what aperture I want and a good deal of the time what ISO but working out exposure without a few shots is proving hard. This may lily be because I am usually shooting in lowish light by hand as a tripod would really get in the way usually. I am wishing now that I went with a ball head instead of the pan head but I can always buy the ball head and swap it out and then would still have the pan head for video. My suggestion would be to start shooting in AP mode as it does exposure but you control aperture and ISO.

    Cool now I dont even have to do the comparison thing with my camera even though it would be a bit different, a EF-S and a EF mount lens on the same camera. Fort some reason I thought the 50, 60, and 70D were full frame 9dont ask me why) but that means the lowest full frame canon is the 6D and that really needs refresh. I dont plan on going full frame anytime soon, its just something to keep in mind.

    The only way in which I could replicate this was with my 17-40mm. I used my Canon 5D Mk II and my Canon 50D. The Canon 50D is a 1.6 crop. so to get the same results I did 17mm x 1.6 to get the correct focal length to shoot at on my 5D MK II which was 27.2mm. My 17-40mm has 28mm marked on it so I just used that...

    It is all about playing with the camera and getting different results for yourself. The F/1.8 aperture is hugely different to the f/3.5 of the 18-55mm at 18mm. The shallow depth of field is great and you can get some amazing pictures if you combine the shallow depth of field with a close up image (you get Bokeh. Do a quick good of that.)

    A 50mm EF lens will give the same focal length as a 50mm EF-S lens on a crop sensor. The same applies to if you were able to get both of these lenses onto a full frame camera. They would be identical focal lengths.
     
    The difference is when you have one lens and two camera bodies. If you take the 50mm EF lens and put it on the crop sensor camera, you are actually getting an 80mm focal length. If you were to put it on the full frame sensor you would be getting a 50mm lens. This is because of the crop of the crop sensor camera has. This crop effectively  increases the focal length.
     
    If you took a 50mm EF-S lens and put it onto both camera bodies, you would have a 80mm focal length on the crop sensor camera and a 50mm focal length on the full frame camera ( I know that the EF-S mount wont work on the full frame, just saying hypothetically for this.)
     
    From the link I posted: "For example, a Nikon APS-C crop sensor has a 1.5x multiplier. When a Nikon 50mm f/1.4 lens is attached to that Nikon DSLR, the focal length is multiplied by 1.5x and effectively acts like a 75mm lens on a full frame DSLR."

    This only applies between full frame cameras and crop sensors. If you use a 50mm lens on a full frame sensor it is 50mm's on a full frame there is obviously no crop as it is "Full" frame. On a T2i you have a crop sensor of 1.6 . You have to multiply the crop sensor by the focal length which would actually make the 50mm lens on the T2i 80mm.
     
    Another viable option for OP might be to get a FD 50mm for ebay or the like and get a FD to EOS adapter. This will allow him to use any old Canon lenses.

    The main thing that I would suggest for OP is that he goes down to his local camera shop which has one of these and testing it out. This lens is great for shooting in low light situations where the use of flash isn't possible and also the use of its wide aperture for narrow depth of field. Trying it out is the best thing when it comes to a new type of lens (new to OP) like this.

    The simple answer is no. You do "need" a prime lens.
    Also the lens you mentioned is plastic, it rattles and hunts to focus and is noisy.
     
    BUT
     
    With that lens you will amaze yourself with the shots you will take. Full open at f 1.8 the background just melts away.
    When I got mine I really didn't like it. It took me a few weeks to learn how to get the best out of it and now it rarely leaves my T5i.
     
    A quick example below.
     

     
    Buy this lens today.
    If you don't I will come round and slap you with a wet fish.

    The best thing about prime lenses is the ability to let in more light due to the wider aperture which gives you more freedom to bump up your shutter speed and/or lower you ISO to get a more sharp and clean image. This is especially true in low light situations. I suggest you use your 18-55mm kit lens at 50mm and see whether you are comfortable with the focal length. It's a killer lens for the price, and if you don't like it you can sell it quite easily.

    I'm aware of the crop factor, but the 50mm setting on his kit lens is the same focal length as the Canon 50mm 1.8 prime lens he is considering in buying.
     
    Yes the focal length is 80mm equivalent on a full frame camera, but that's irrelevant because:
    1) He doesnt have a full frame DSLR
    2) His lenses already cover a decent range, therefore he can just play with the focal lengths and find out whether a particular fixed prime lens would suit him.
     
    Actually to get a 50mm focal length on a full frame he would have to set the 18-55mm kit lens to around 30mm. Setting the telephoto lens to 80mm will give a focal length of 128mm on a full frame.

    EOS M is great if you really need something super compact to use for casual shooting, but then something like the Sony RX100 would be better for around the same price.
     
    But let's say he wants to take it more seriously and invest in some lenses that he can also use when he upgrades the body down the track. He would have to buy the mount adaptor and that's pretty hard to find let alone expensive. I haven't personally used an EOS M but I've heard the AF is pretty whack.
