Can I use EF lenses on my R system?

Yes, with a handy adapter! Canon make a number of adapters for this, so feel free to have a chat and we'll work out which one will suit you best. 

Which is better, Canon or Nikon?

Canon of course! We're on the Canon page! But seriously, this is not a clear cut answer. It's all down to personal preference, what you want to accomplish and what feels right for you.. But, as you're here, then.....yes, Canon is better.....ssshhh don't tell the others!

What does IS mean?

Simply put, IS stands for Image Stabilisation. Clever little systems inside cameras, lenses and binoculars to help keep things steady for better pictures and better viewing. Ideal if you're into snapping or observing your subject at a distance. 

Are Canon IS binoculars waterproof?

Some of them, yes! As these all need batteries (And a way to change them over) not all of them will be fully sealed against the elements. Canon will include "WP" in the title if they are. See all Canon binoculars here.

What lenses are good for Macro photography?

The EF 100mm f2.8L IS USM is a fantastic choice for macro photography, especially if you were interested in insects and small creatures that may scare easily if you get too close. The 100mm will allow you a 1:1 life size image reproduction without disturbing the subject. 

For the budget conscious among you, the EF-S 35mm f2.8 IS Macro STM is a smaller and lighter option for those interested in subjects that won't run away. Suitable for close up food photography, plants and jewellery.

What's the difference between EF and EF-S lenses? 

The lens mount, of course! If you have a "Full frame" camera, you can only use "EF" lenses, but if you have a "Crop frame" camera you can use both EF and EF-S. If you're not sure what camera you have, carry on reading.. Look at the front of the lens mount on your camera (Yes, you) does it have a red dot and a white square? Then it's a crop frame camera. Just a red dot? Full frame. (Now you know!)

What's the difference between Prime and Zoom lenses?

When we talk about prime lenses and zoom lenses we're talking about focal lengths.. Simply, you can change the focal length on a zoom lens, but not on a prime. Why would anyone want this, you ask? Sensible question, carry on below dear reader.. 

Are Prime lenses better than Zoom lenses?

Often, but not always. Prime lenses are often faster and so better for shooting in low light or for getting that nice "Bokeh" effect you've read about online. However, this does mean that you loose a bit of flexibility..

Let's explore an example.. Say you're busy shooting some deer in the distance when a majestic golden eagle lands next to you and starts flexing. With a zoom lens, you might be able to reframe that mighty eagle with a twist of the lens barrel, however with a prime you may have to entirely swap the lens over before you can frame the subject properly.

In other words, sometimes with a prime you have the wrong lens on at the wrong time! 

To the credit of prime lenses though, they are often quick and high quaity, some lighter than their zoomy equivalents. 

What's the difference between full-frame and crop-frame?

We're talking about sensor sizes here and the general rule is, the bigger the better. Canon currently use two different sizes in their EOS, R and M range. APS-C or crop frame is smaller than 35mm format or full frame. Full frame cameras are usually the choice of pros or serious amateurs as they usually provide the best low light performance and dynamic range. Crop frame cameras are normally smaller, lighter and more affordable so that's a bonus for that team! 

What Canon compact would you recommend?

Well, that all depends on what you're trying to do.. But the Powershot G7X III is a big hit with serious photographers and vloggers alike thanks to its big sensor and flip up screen. 


Explain the difference between USM and STM?

No.. I mean.. Err.. Actually it's quite simple! These codes are all about autofocus. USM refers to the ultrasonic motor in the lens, which means fast and snappy focus. STM refers to the use of a stepping motor which are designed to be quiet and smooth, which makes them better for video, if you're planning to use the auto-focus. 


Are L lenses really that much better?

Of course, they've got a red band on them, just like the van in the A-Team. But alongside that, they are usually built to higher standards than regular Canon lenses, featuring better dust and moisture sealing (Though this does vary from lens to lens). Canon also use special types of lenses inside them, including aspherically ground, fluorite or ultra-low dispersion glass elements, which mean better pictures!
