Conclusion

In terms of image quality, the Olympus M.Zuiko Digital ED 25mm f/1.2 PRO is capable of delivering some truly outstanding results. Traditionally, prime lenses can often be a little lacklustre at their widest apertures, but with this lens, you get exceptional sharpness throughout the range - it’s something you can happily use at f/1.2. 

Bokeh is beautifully rendered, while the clarity and colours that the lens is capable of producing are wonderful. 

It is by no means a small or light lens - one of the key proponents of the Micro Four Thirds systems, but, if you're using one of the professional level cameras, such as the Olympus OM-D E-M1 Mark II, or the Panasonic GH5, it doesn’t feel out of place. If you're using an entry-level model, such as the Panasonic GX80 or the Olympus PEN E-PL8, there are other primes which will probably serve your needs over this lens, but for professionals looking for the best in image quality, it is very desirable. 

It’s also worth remembering that while we are describing this lens as large and weighty, that’s by Micro Four Thirds standards. When you compare it to something of similar specification and quality for DSLRs or CSCs with an APS-C or full-frame sensor, the Olympus M.Zuiko Digital ED 25mm f/1.2 PRO lens starts to actually look quite small. 

Being a standard prime means it’s suitable for a wide range of subjects, including portraits, street photography, still life and more. It’s a very flexible focal length that is enjoyed by many photographers for good reason. Focusing is quick and accurate, while manual focusing is made so easy by the snap focusing ring and smooth mechanism. 

Now for the major potential drawback - this is by no means a cheap leans. It currently retails for in excess of £1,000. This makes it perhaps more likely to be bought by professionals than enthusiasts, but, you do get an extremely nice lens for your money. 

Both Olympus users and Panasonic users are likely to be tempted by the Olympus M.Zuiko Digital ED 25mm f/1.2 PRO, but if you’re looking for a smaller or cheaper alternative, there’s an Olympus 25mm f/1.8 option, or a Leica 25mm f/1.4 option available.
