The brand new Pentax Okay Lens to Sony E-Mount Monster autofocus Adapter is now in Inventory at BHphoto (Click on right here).
The brand new adapter has been examined by Dpreview. The conclusion:
Whereas its efficiency will range relying upon your chosen lenses and digicam our bodies, we discovered the LA-KE1 adapter to yield moderately lesser AF efficiency than is natively accessible from Pentax our bodies, even once they’re utilizing their slower contrast-detection AF in stay view mode.
However we additionally discovered that getting focus within the ballpark first helps considerably with efficiency, particularly for screw-drive lenses or these with lengthy focus throws. And whereas it wasn’t as peppy because the native AF, we discovered the LA-KE1’s AF pace fairly acceptable for all however very energetic topics like sports activities.
And that tradeoff in efficiency brings extra potential than the apparent benefit of having the ability to use your Pentax glass with a mirrorless physique. For one factor, it means entry to resolutions past the Okay-1 II’s 36 megapixels, and multi-shot high-res imagery that (in contrast to Ricoh’s) will increase the pixel depend nonetheless additional.
For one more factor, it beneficial properties you entry to Sony’s eye-detection autofocus algorithms, which may be massively useful for portraits of individuals and pets alike. And also you’ll have dense AF protection throughout the body, in contrast to Pentax’s phase-detection AF which has comparatively few factors and is centrally-focused.
The main focus drive delivers adequate accuracy not only for Sony’s cameras to nail focus in a exact space of the picture, but in addition to permit for issues like effective changes to focus when tethering. In truth, I even efficiently used it for focus bracketing with Sony’s Imaging Edge Distant and the open-source B8Stack utility.
It’s a fantastic pity that assist for video seize isn’t attainable, as that’s lengthy been a weak spot of the Pentax Okay-mount which, if solvable, might’ve been an enormous deal for Pentaxians. However MonsterAdapter has to work throughout the boundaries of what Sony’s lens adapter assist permits, and so for now respectable Okay-mount video should stay a pipe dream.
Actually, the one sticking level is the cost. There’s no getting round the truth that that is fairly an costly adapter even when in comparison with related merchandise from a lot better-known names. For instance, Sony’s personal LA-EA5 adapter is available in at round $250, as do each Sigma’s MC-11 adapters for EF and SA-mount lenses.
However Sony and Sigma can subsidize its prices with physique or lens gross sales, whereas the MonsterAdapter’s fortunes should stand by itself gross sales alone. The excessive pricetag isn’t fully unprecedented, both, as Metabones’ EF-mount adapters additionally are available in at round $400.
