Panasonic announced the 12-35mm ƒ/2.8 ASPH POWER OIS LUMIX G X VARIO zoom lens in May of 2012, offering the equivalent of a 24-70mm (in 35mm film terms) ƒ/2.8 zoom lens for their micro four-thirds camera bodies. The lens offers a constant ƒ/2.8 aperture across its range of focal lengths.
The lens was designed for the micro four-thirds mount, and thus will not mount on other four-thirds camera bodies. It should however mount on other micro four-thirds bodies, such as those produced by Olympus. The lens uses 58mm filters, and ships with a petal-shaped lens hood. At the time of writing, we have no pricing information.
Panasonic Lumix G X Vario 12-35mm F2.8 ASPH Key Features
- 24-70mm-equivalent central length; continuous F2.8 highest possible aperture
- ‘Power OIS’ visual picture stabilization
- Nano area covering for reduction of area and ghosting
- ‘HD’ status – near quiet function during video shooting
- Micro Four Thirds install for Panasonic and Olympus cameras
Panasonic Lumix G X Vario 12-35mm F2.8 ASPH Body And Design
The 12-35mm represents a leaving from previous Lumix G contacts in terms of construction. The back section of the gun barrel between the zoom capability band and the install is metallic, as is the guide concentrate band with its finely-milled ridged hold. This instantly gives an impact of construction that Panasonic contacts have recently was missing. The 12-35mm is also Panasonic’s first lens with any kind of ecological closing, although it’s uncertain whether this expands beyond the thin rubberized closure that circles the lens install.
This impact of top quality products is strengthened by the wonderfully-smooth zoom capability band action, that competitors Cannon and Nikon’s top-end contacts for its silkiness of function. It moves about 80 levels between the wide and tele roles, which allows you to fine-tune your arrangements with some perfection. The electronically-coupled guide concentrate band on our-preproduction example doesn’t have quite the same level of smoothness of spinning, but it does offer extremely precise guide concentrating with a extremely well-tuned responsive ‘feel’, which is all that really matters.
Lens body system elements
- The 12-35mm uses the all-electronic Small Four Thirds install, significance it will work on Olympus’s PEN and OM-D electronic cameras, as well as on Panasonic Lumix G techniques. In this perspective you can just make out the thin rubberized closure that encompasses the install, and helps secure against dirt and water getting into our techniques at this relatively insecure point.
- The narrow line is 58mm, and does not move on autofocusing, which should please narrow customers. Next to it is the bayonet install for the petal-type lens bonnet (see below).
- The zoom capability band is 16mm extensive, and moves roughly 80 levels clockwise from 12mm to Negatives, providing excellent compositional control. Its action is magnificently sleek and accurate – a cut above Panasonic’s current zooms for Small Four Thirds.
- Olympus customers may wish to remember, though, that (as usual) this is the other of spinning in comparison to their M.Zuiko Digital zooms.
- The finely-ridged guide concentrate band is 10mm extensive, and uncommonly is metallic. Like most Small Four Thirds contact contacts guide concentrating is ‘by wire’, and designed such that fast spinning of the band changes concentrate range quickly, while slowly spinning can be used for excellent concentrating. Panasonic’s execution works especially well, but it does mean that there’s no range range on the lens.
- Thankfully the 12-35mm has a physical OIS change (many latest Panasonic contact contacts have devolved this operate to a selection establishing on the camera). For customers of Olympus electronic cameras, this allows relatively easy changing between visual and in-body IS techniques.
- The 12-35mm comes with a bayonet-mount petal-type lens bonnet, that turns around nicely for storage space.
Panasonic Lumix G X Vario 12-35mm F2.8 ASPH Images Quality
The Panasonic 12-35mm ƒ/2.8 provides very distinct outcomes, reliable across all central measures. The lens provides almost tack-sharp efficiency when used open up at ƒ/2.8, with only a bit of smooth in the excessive corners; avoiding down to ƒ/4 provides strong edge-to-edge sharpness. In fact, ƒ/4 seems to be the best aperture for this lens, as outcomes actually break down very a little bit when the lens is ceased down further than that. This is all very comparative, though – outcomes are still extremely distinct from ƒ/5.6 through to ƒ/11, with diffraction restricting only becoming essentially noticeable at ƒ/16. At ƒ/22, we mentioned some mild smooth across the structure.
The lens provides excellent level of potential to deal with chromatic aberration. If there is any to be mentioned at all, it seems to be most at the broader end of the lens’ zoom capability range – 12mm – and is quite simple, showing as green fringing on areas of high comparison. It seems to be only in the excessive sides. At other central measures and apertures, it is very hard to see.
The Panasonic 12-35mm ƒ/2.8 does display some mild area covering when used at its 12mm central duration across all apertures, and when taken at ƒ/4, just at 12mm. The figures are little – at its most severe situation (12mm at ƒ/2.8), you’re looking at excessive sides which are a half-stop deeper than the center of the structure. At other configurations, there is less area covering to keep in mind, if any at all.
There’s not much to add to this review that the numbers don’t already show – the pre-production version of the Panasonic 12-35mm ƒ/2.8 that we tested showed excellent performance across the board. In addition, it boasts image stabilization and a splash- / dust-proof design: there is a lot to like here, making it an attractive upgrade for GX-1 users. The only unknown will be the price, which we’re sure can’t be cheap for a lens this good.
For a contact, there is very little distortions at the extensive end, which indicates to us that there is probably some post-processing going on in the digital camera to reduce the effect. Gun barrel distortions is very mild when used at 12mm, hardly recognizable at all, and between 18-25mm, there is no distortions at all. At 25mm-35mm, there is some recognizable pincushion distortions in the sides, but it is not absolutely apparent.
The 12-35mm ƒ/2.8 X provides extremely quick auto-focus outcomes, inspired by an in-lens electrical motor that’s extremely quick and very silent. Filtration connected to the front part of the lens won’t move, making life a little easier for polarizer customers.
The lens isn’t a separate macro lens, providing only regular outcomes for macro – just 0.17x zoom, with the lowest close-focusing range of around 9 inches wide (25cm).
Build Quality and Managing
As with most small four-thirds contacts, the Panasonic 12-35mm ƒ/2.8 is quite little, and relatively mild – they weigh just 305 grms (just 10 ounces). The pre-production form of the lens we examined is a little bit red in its shading, but we have learned by Panasonic that the delivery edition will have the traditional black-grey shading of their lens collection. The lens install is steel, and the 58mm narrow discussions are nasty. The lens also provides a rubberized grommet at the install end for protection from water and mud.
