The longer the focal length, the narrower the angle of view and the higher the magnification. The shorter the focal length, the wider the angle of view and the lower the magnification. That way, you figure out what you want, you position yourself so that you’re in the right place, and you get ready to take the shot even before you hold the camera to your eye. Such a lens encourages you to envisage the composition whilst keeping your specific focal length constraints in mind. The photographer must move to frame the image, which is more time consuming but also makes you think more about compositional aspects of the shot. With a fixed focal length lens, the emphasis is on ‘fancy footwork’. This allows you to capture a series of wildly different images, which can make us lazy with our compositions. With a zoom lens, you can change your composition simply by changing the focal length. It wouldn’t be within the spirit of the challenge to use, say, a 50mm lens and then crop the image effectively to 200mm. Ideally aim to use the lens magnification that gives the field of view closest to what you see.įor obvious reasons, your images should not be cropped. To save having to find out the focal length of your phone, which is not always straightforward, we suggest that mobile phones should simply be used either at their standard focal length, or even better perhaps at a x2 or x3 magnification if that is something that you can readily achieve with your particular phone. The standard lens is typically quite wide angle, often with a focal length of 4 – 6mm (4.25mm is equivalent to 26mm on a full-frame camera, so within the suggested range). If you don’t have a fixed-focus lens, then you can just set your zoom lens at a particular focal length and stick to it. However, to maintain some consistency between participants, we suggest that you aim for a focal length with a full frame equivalent in the 24 – 70mm range. On a standard crop sensor this is the equivalent of about 35mm and on a 4/3 camera, 25mm.ĭon’t worry if you don’t have a 50mm fixed-focus lens. You could even choose to do this during a Cuppa and Capture or Photo Walk outing.Ī 50mm prime lens, often called a ‘nifty fifty’, corresponds on a full frame camera to roughly the field of view we see with our eyes. You may decide to follow Roger’s example and do this throughout the whole of October, or you may prefer to limit your engagement to just one day – or maybe somewhere in between. The pictures can be any genre or subject you like. The idea of this Challenge is to use a lens with one particular fixed focal length to take all your photographs. He will be using only his 50mm fixed-focus lens throughout the month of October, and his comment was “anyone fancy joining in?”, so it seemed a good opportunity to extend Roger’s personal challenge (with his permission) to all members in the form of our next Club Challenge. ![]() This challenge is inspired by Roger Walton’s October challenge to himself, mentioned recently on Facebook. The deadline for submission of your images for this Challenge has been extended until the end of November.
