Sample images to download and compare Four Thirds super wide angle lenses
What is a super wide angle lens? My personal definition is one that can go wider than a traditional 28mm (14mm on Four Thirds) wide angle lens. For that reason, I've included the Olympus Zuiko Digital 12-60mm f/2.8-4 ED SWD, though the samples here only cover 14mm or shorter.
Clockwise from left, 7-14, 11-22, 12-60, 9-18 Zuiko Digital EDs
We've in addition to the 12-60, we've included samples from the near-legendary Zuiko Digital 7-14mm f/4 ED, the classic Zuiko Digital 11-22 f/2.8-3.5 ED, and the brand new. more affordable, 9-18mm f4-5.6 ED. Ideally, I'd like to have included the Sigma 10-20mm f/4-5.6 EX DC HSM, especially as it is very competitively priced compared to the 9-18 and 11-22 and slots neatly between the two. But that will have to wait for another time.
Download links are on page 2 of this article, but first, here are some comparisons of the fields of view from 7mm all the way through to 14mm. It's remarkable what the difference between a millimetre or two of focal length can mean in terms of coverage:
7mm view (14mm equivalent)
9mm view (18mm equivalent)
11mm view (22mm equivalent)
12mm view (24mm equivalent)
14mm vew (28mm equivalent)
And below is a table to show the relative maximum apertures throughout the focal length range, up to 14mm:
|Zuiko Digital 7-14mm f/4 ED||4.0||4.0||4.0||4.0||4.0|
|Zuiko Digital 9-18mm f/4-5.6 ED||-||4.0||4.2||4.4||4.8|
|Zuiko Digital 11-22mm f/2.8-3.5 ED||-||-||2.8||2.9||3.0|
|Zuiko Digital 12-60mm f/2.8-4 ED SWD||-||-||-||2.8||2.9|
