Hiya
I own a canon 550d which is NOT a full framed camera. I have heard how amazing the 50mm 1.4 lens is and want to purchase one myself. To get the same results as this lens gets on a full framed camera do I have to buy a 35mm 1.4 lens which is 3 times more expensive!!!!
A little confused....if I buy the 50mm 1.4 this would be the equilivant to a 80mm lens on my 550d!?
Any insight on this issue would be greatly appreciated.
Thanks!!!

Long story short - a 35mm or similar focal length lens on a crop sensor body will fit about as much in the view finder, as 50mm in a full frame sensor body.

The Canon 35mm f/1.4L is a professional grade lens that provide great quality (compare to the 50mm f/1.4 or f/1.8 of the same brand) with a much greater price.

Another option for you is to get the Sigma 30mm f/1.4! Lots of people using a crop body praise about this particular lens and it can be bought at anything between $300 - $450: depends on 2nd hand, grey import etc.... But I personally would recommend to buy from a Australian dealer to get the support and service you quite possibly would needed if you decided to go for the Sigma option.

I would be advising you to look more into a " walkabout " lens. One that is going to be on your camera most of the time. There are a lot of options to choose from. 18-55, 24-70, 24-105 just to name a few. You can get a good walkabout that is high spec and will serve you well. Have a good think about what you would be photographing , then decide on the right focal length/s for you. Best of luck.

What lens's do you have now, I have a 450D and a 7D, I have 50 F1.8 and 24-105 and they alternate between the two cameras 95% of the time, the other 5% is when out doing wildlife and the sigma 150-500 comes out. I do have the twin lens kit lens, but very rarely used now.

In hindsight, if I did not have the 50 F1.8, I now would have got the sigma 30 F1.4 possibly instead.

I agree with PH005 & Dave that a good 'walkabout' lens is the go. I have a Canon 500D & use the Canon 24-105L lens. The image quality is excellent & you have the option to zoom in & out as you wish. I use this lens 95% of the time & pretty much 100% when travelling.

I suspect that the 'amazing' reports you have heard about the 50mm 1.4 have less to do with the focal length (or apparent focal length) and more to do with the shallow depth of field you can achieve with a lens like this.

Your profile indicates you have the two kit lenses at present. Why do you want the 50mm lens? Do you plan to use it for a particular type of photography, such as portraits? Knowing your intentions might help us to give you better advice.

I think you need to decide what focal length you want and what aperture you need.

There is plenty of amazing lenses, but what do you want to do?

That cat`s tail keeps getting into my eye:p


ok just read your profile, you have the 18-55 and the 55-250 , so a prime lens with big aperture like a 50, 1.8 or a 50 1.4 would be a good addition.
Big aperture for low light ability and for shallow depth of field. The 50 1.8 is cheap excellent image quality but noisy focus, the 1.4 also excellent image quality better focus system and you can focus manually. Is the 1.4 worth 4 time the price, probably not but its better build and nicer to use and I wished I had bought it.

If you like portrait photography you may enjoy the 85 1.8 or even the 100 2.8 macro.
macro is fun have you considered a lens that can double as portrait lens, low light and as a macro lens?
