Chromatic aberration is the lens' inability to focus on the sensor or film all colours of visible light at the same point. I really like the bright 25mm marking on the lens, making it quite easy to identify, especially in the dark.

This means straight lines will look, well, straight (see the images above the flowers for an example). is a solid option whether you're looking for a companion to your 'kit' zoom lens or you just want something small and fast to shoot with.Dedicated to extreme close-up imaging, this lens is a specialized macro lens for photographing subjects at magnifications greater than life-size. Large, clear numerals on both sides of the focus barrel enable your focus puller to work from either side of the lens without remarking or flipping the lens upside down. There's no optical stabilization, though this shouldn't matter for the vast majority of shooters, as almost all modern Micro Four Thirds bodies have internal IS. Camix LTD is an Introducer Appointed Representative of Pay4Later Limited, trading as Deko, which is authorised and regulated by the Financial Conduct Authority (FRN 728646). The hard-to-correct longitudinal variant, also known as LoCA, is barely noticeable in photos from the 8-25mm F4.

If both sensors have the same number of pixels, the amount of light reaching each pixel for the same image is exactly the same. there’s less than a stop of light fall-off in the corners, which will rarely be noticeable in normal use. The lens provides a 50mm focal distance (35mm camera equivalent) similar to that of the human eye when mounted on a Micro Four Thirds camera and takes advantage of Panasonic's 240fps contrast detection AF system. It is very easy to induce quite obvious flare, creating image artefacts and also reducing contrast to a soft haze.It is a bit on the short side for portraits closer than half length because as we close in the perspective becomes too steep and noses become too big and distorted.

A scratch resistant PTFE hard anodized finish is provided on all Cooke lenses, providing a durable, hard-wearing surface to meet the most demanding environmental conditions.

Sample images in this review were edited in Adobe Camera Raw with adjustments limited to white balance and exposure parameters. and full-frame 35mm (36x24mm), which enables kit to be made much more compact and this includes lenses where there’s the benefit of a 2x crop factor. ccFusion Xpres™ injectable bone putty is a combination of demineralized bone (DBM) with mineralized cancellous chips and biphasic calcium phosphate (BCP). That's precisely the difference (or less) between the PL25 and the other lenses when stopped down to f2. All Cooke miniS4/i primes have a common fixed front diameter of 87mm, except for the 18mm which has a front diameter of 110mm.
