A 50mm is one of my favourite lenses and one of the best lenses for family photography. The 50mm lens is close to what our eye naturally sees and is an excellent place to start. We can fit so much in but we do need to be careful of distortion in the corners which can be an issue for family portraits. Wide angle lenses give us flexibility on our angle of view. With long lenses we can photograph things further away and they also compress perspective which can be very flattering in portraits. Yes you read that correctly!ĭifferent focal lengths give different perspectives to our pictures and can be used in different situations. Lenses come in a huge variety of focal lengths from Canon’s EF 8-15mm f4L fisheye USM to the incredibly rare Canon EF 1200mm f5.6L USM lens which was on sale in 2014 for £99,000. These cover pretty much all eventualities but there are lots of different zooms on the market, from those aimed at travel photographers such as the Canon RF 24-240mm f/4-6.3 IS USM or the long lenses aimed at sports or wildlife work such as the Canon EF 100-400 f/4.5-5.6L II USM.

The most common zoom lenses used by professional family and wedding photographers are the 16-35mm, the 24-70mm and the 70-200mm. We can change our angle of view without needing to change our lenses and so can move from a wide angle to a telephoto view in a matter of seconds. Zoom lenses are designed to make life easier for us as photographers. Instead I can quickly move, or ‘zoom with my feet’, to get the perfect angle. I don’t waste time tweaking my focal length. Personally, I love to shoot with primes as I find them more instinctive to use than zooms. They’re also usually optically superior to zooms although modern zooms are excellent. One of the benefits of prime lenses is that they’re usually faster than zooms (only the Canon RF 28-70mm f/2L USM has a maximum aperture faster than f2.8). This is in contrast to zoom lenses that allow you to change the focal length, such as the 24-70mm or 70-200mm. STM stands for Stepper Motor Technology which means the motor in the lens is designed for quieter and smoother focusing which is particularly important for shooting video.Ī ‘prime lens’ is a lens that has a fixed focal length such as 35mm or 50mm. IS stands for Image Stabilizer which means the lens has stabilisation built in. Where you see USM this refers to the small motor built into the body of the lens and means the lens will focus faster than standard models. Canon are bringing out more of these all the time and the new lens line up is very exciting for us photographers with incredible technological advances bringing new opportunities for creative imagery. I am slowly moving towards a completely mirrorless set up and so I will eventually only shoot with RF lenses. The RF or EF in the lens names refers to the lens mount on the two Canon EOS systems: RF refers to lenses that fit on the new mirrorless R-System cameras while EF lenses are on Canon’s traditional DSLRs.Īs you will notice in this article, I use lenses with both EF and RF lens mounts as I shoot with both camera systems. I shoot entirely with Canon lenses and am a Canon Ambassador so I’ll be referring to Canon lenses in this piece. For example you can use Canon’s EF lenses on its RF cameras with an adaptor but you can’t use RF lenses on EF cameras. Some third-party manufacturers such as Sigma and Tamron make lenses for different camera systems, but you always need to check that the lens you buy will fit the camera you own.

Lenses are designed to work with a specific camera system so a Canon lens won’t work on a Nikon body for example. the maximum aperture moves as you zoom the lens. Some zoom lenses have a variable maximum aperture such as the Canon EF 100-400 f/4.5-5.6L II which means that at 100mm the lens has a maximum aperture of f4.5 while at the longer 400mm length the maximum aperture is f5.6, i.e. the Canon RF 50mm f/1.2L USM has a maximum aperture of f1.2. The widest aperture of a lens is described at the end of the lens name, e.g. Very fast lenses, which I tend to use indoors, will allow me to shoot at f1.4 or f1.2. For this guide, I’ll be talking about lenses with an aperture of f2.8 or above as fast.

What is considered fast has changed over the years with advances in lens technology and, of course, one lens can be fast in comparison to another. These are lenses with the option to shoot at wide apertures. I’ll start by running you through some of the basic terminology. It can be hard to keep up and work out what you need to know now and what you can learn later. People talk of fast lenses and bokeh, tilt-shift and hyperfocal distance. When you first enter the wonderful world of photography, the terminology can feel overwhelming.
