Which cameras better, Nikon or Canon?

I'm a graphic designer and have been taking pretty good pictures on my Olympic camera but I want something a little more advanced.
I hear nothing but good things about Nikon and Canon.
I would like to know which is the best camera to use to take good photography photos and for videos to upload onto YouTube? Which ones would you suggest?

You are going to have to do more research and then decide for yourself.

Why?

Most professional photographers use Nikon and Canon camera systems because they have the most available lenses and accessories and the pro versions can stand up to the hard use that is associated with professionals.

Now, after you have spent some time on the Nikon and Canon websites and found the cameras that have the features you want as well as the ones that fit your budget, visit the following websites.

* DP Review and read the professional reviews of those cameras. Take good notes
* Visit DXOmark.com and compare the sensor performances of your choices.

This should give you a good idea of which two or three cameras will fit your needs.

With that list, visit a proper camera shop and hold each in your hands. One of those will be just what you want.

There's NO right answer that can be posted here. I use Nikon D300 and D3 cameras with my lenses, even the ones from the early 1970's. Others use Canon 7D or D1s variants which were left over from when they were shooting using Canon EOS 35 mm cameras.

It will only be possible for you to pick the right camera for you, by doing your own research. Do not expect us to spend your money on anything, especially camera gear

If you have a small budget, then you will want to look at the entry level cameras made by those camera companies like the Nikon D3300 or Canon T5/1200D

NOTE: If you buy a Canon entry level, cropped sensor camera, any EF-S lenses you b;uy will hve to be replaced with Canon EF lenses if you ever upgrade to a full frame Canon EOS camera. Full frame Nikon cameras can use either the FX or DX lenses

Both manufacturers make equivalent quality cameras. Pentax and Sony also make nice cameras, so look at their lineup.

Since you're a graphics designer, you may have friends in the industry who shoot a certain camera manufacturer. Buying the same manufacturer means you can borrow accessories like lenses and flashes for those odd projects.

The Sad truth: If you can't get good pictures with an Olympus, you won't either with a Nikon or Canon.

Arggghhhh!
Why do so many people keep asking this?
They are both excellent cameras and you should decide which model has 1) all the features you want. 2) is within your budget. 3) Feels comfortable when you handle it.
Whether you buy a Canon or Nikon does not matter; you will get good results from either make.
But, then, what's wrong with your Olympus? Are you just changing for the sake of it?
Lastly, if you intend taking lots of videos, why not keep your Olympus for stills and buy a Camcorder/ Video Camera for your videos?

"something a little more advanced" sounds like a serious case of the "wants". And that is fine, if that is where you are going. I'm a little more frugal and would ask myself the question, "Is there anything that I want to do with photography that I can't do with my Olympus?" If the answer is nothing, then that is what I would do about a new camera.

1) Sony's SLTs are better for video than any DSLR. Nikon DSLRs use Sony sensors (so do Pentax, for that matter).

2) Many people who rave about a specific Canon/Nikon model have never used anything else.

3) Pentax were making DSLRs before either, and offer better specification (ability to meter with MF lenses, pentaprisms, weather-sealing) at lower prices.

4) If your OLYMPUS is one of the Evolt DSLRs, it will do anything a Canon or Nikon can do - you just have to learn how.

5) Only Canon and Nikon's DSLRs are worth the candle (unless you look at their over-priced, high-end compacts), and they're no better than anyone else's. Both manufacturers shout very loudly.

Frankly, anyone asking this question shouldn't be allowed within 50 feet of a decent camera.
