Canon EF 50mm f/1.8 II
Delivers superb results for just £79!
Construction: 6 elements, 5 groups
Filter Thread: 52mm
If you're a Canon user, the EF 50mm f/1.8 II represents excellent value for money. When it's connected to an APS-C DSLR it's equivalent to 80mm, whereas when it's used with a full frame model it offers a field of view that's not too dissimilar to what we see through our eyes. Small and lightweight, the shallow depth of field this lens produces is truly stunning.

Olympus 45mm f/1.8
A must-have for Micro Four Thirds users
Construction: 9 elements, 8 groups
Filter Thread: 37mm
This portrait prime lens is equivalent to 90mm in 35mm terms and delivers an outstanding set of MFT results that are strong enough to encourage use of the maximum aperture.
Having the option to shoot at f/1.8 also means a lower sensitivity setting can be used, resulting in cleaner images that are free of noise in dimly-lit conditions.
Nikon AF-S 85mm f/1.8G
A great portrait lens for full frame DSLRs
Construction: 9 elements, 9 groups
Filter Thread: 67mm
With a surprisingly bulky and unexpectedly lightweight design, this 85mm prime suits full frame DSLRs slightly better than APS-C models, where it's equivalent to 127.5mm.
Autofocus is accurate and remarkably quiet. The only thing missing is a vibration control system, but to be fair, it's hardly essential on a lens of this type and would raise the price.
