Sigma 16mm f/1.4 DC DN Contemporary

The Sigma AF 16mm f/1.4 DC DN Contemporary lens gives an excellent performance, a reasonable price and a very bright f/1.4 maximum aperture, which all add up to a very desirable package, that will be appealing to Micro Four Thirds photographers.

Kowa Prominar 8.5mm f/2.8

The Kowa Prominar 8.5mm f/2.8 is a classy-looking lens, it's beautifully made and the results are excellent. AF would make focusing much easier, but it can be worked around and still leave the lens being very satisfying to use. At least with the large amount of depth of field available there is some leeway at longer distances. 

In summary, it's a great lens that is delightful in use and delivers the goods.

Venus Laowa 7.5mm f/2

If ultra-wide angle lenses gel with your style of photography, then this is a great little lens. It's easy to use, gives fantastic results and is light and compact. It is also reasonably priced compared to the alternatives. In addition, it is very bright and this is unique at this focal length, which opens up new possibilities for image making.

Meike 6.5mm f/2.0 Fisheye

The circular fisheye lens is a fairly specialised tool, the frame filling designs being much more prevalent and arguably more generally useful. However, who could argue with that f/2 aperture, with the quality of the results, with the excellent price, with the solid construction? The only difficulty is that judging manual focus is well nigh impossible, but the huge depth of field can cover most situations very well.

If we want to delve into the fisheye world at a reasonable cost and no compromise on quality, then this could well be a very strong contender.

Voigtlander 10.5mm f/0.95 Nokton

Overall this is another fine, fast lens from Voigtlander for Micro Four Thirds. Those shooting video will appreciate the option of a stepless aperture and many will enjoy exploiting the fast maximum aperture and ability to isolate a subject from their surroundings with a shallow depth of field.

Sharpness delivered by this lens is excellent, with acceptable distortion and falloff. It’s a shame CA levels are a little on the high side, but then that is probably unavoidable on a lens as wide and as fast as this. Build quality harks back to a bygone era of brass lenses with a silky-smooth focusing action. As a result, it is sure to win over many fans.

Samyang 12mm f/2.0 NCS CS MFT

Overall, this is an excellent optic that produces images with excellent sharpness, low distortion and low CA. Also, what makes this lens especially interesting is the low price which we're sure will grab the attention of many. 

Tamron 14-150mm f/3.5-5.8 Di III

The Tamron 14-150mm delivers good sharpness and quick autofocus in a compact, lightweight lens that's built incredibly well. The zoom is versatile and overall, the lens offers good value for money. 

Voigtlander 25mm f/0.95 Nokton Version II

Overall, the second version of this 25mm Voigtlander lens is a nice improvement. Those shooting video will appreciate the option for a stepless aperture and everyone will enjoy the fast maximum aperture and ability to isolate a subject from their surroundings with shallow depth of field.

This sample also appears to offer improvements in sharpness and contrast over the copy of the first version we tested some time ago. Whether this is down to natural variation between lens samples, or improvements to the optical construction is difficult to say at this point, without having a few of each lens version to test and compare. The sample tested was more than usable at f/0.95, so long as care is taken to ensure accurate focus. Overall, this is an interesting lens, that should win over many fans.

Voigtlander 42.5mm f/0.95 Nokton

This lens is capable of delivering images of exceptional quality, as well as opening up extra creative opportunities due to the shallow depth of field possible at such fast apertures. It's built well, handles well and although it is a specialist lens, it will be worth every penny to those who will make the most of this lens' features.

Sigma 60mm f/2.8 DN A

The telephoto focal length and fast f/2.8 maximum aperture make this optic a perfectly good lens for portraiture for not a lot of money. Even though this lens is reasonably inexpensive, Sigma hasn't skimped on build or optical quality. It is capable of delivering pin-sharp results from maximum aperture and it is built well enough to be a worthy investment for many years to come.

Samyang 7.5mm f/3.5 UMC Fisheye

Being priced so low, this diagonal fisheye from Samyang for Micro Four Thirds system cameras represents excellent value for money. It produces sharp images and has excellent build quality. With a fisheye lens, it is relatively easy to use manual focus due to the huge depth of field provided.

Sigma 19mm f/2.8 EX DN A Art

This compact lens should make an ideal addition to any Micro Four Thirds kit. Its lightweight, compact size and excellent optical performance are complemented by fast autofocus speeds and good build quality. The lens represents excellent value for money also.

Sigma 30mm f/2.8 EX DN A Art

During testing, this lens proved itself capable of producing excellent results, even at maximum aperture. The lightweight, fast autofocus and excellent build should win this lens many fans, especially with the price being so competitive.
