Panasonic LUMIX G Lens, 25mm, F1.7 ASPH, Mirrorless Micro Four Thirds, H-H025K (USA Black)

Product Information

Announced alongside the flagship OM-1 camera, the M.Zuiko Digital ED 40-150mm F4.0 PRO is its second all-new optic under the OM System brand, after the M.Zuiko Digital ED 20mm F1.4 PRO. It’s a compact, weather-sealed telephoto zoom than employs a space-saving retractable design and promises premium optics. With a zoom range equivalent to 80-300mm on full-frame, it’s designed for use with Olympus and OM System cameras but can also be used on Panasonic Lumix G-series MFT bodies. The Sigma 30mm f/1.4 DC DN is part of a range of bright f/1.4 lenses designed for APS-C and Micro Four Thirds mirrorless cameras, along with the 56mm f/1.4, there’s also a 16mm f/1.4 lens available. The Sigma 30mm f/1.4 gives a 60mm equivalent field of view, making it slightly longer than the “standard” 50mm lens. With an f/1.4 aperture, it’s also a good choice if you need to shoot in low-light conditions.

Bokeh is a word used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such as smooth / creamy / harsh etc. In the Panasonic Lumix G 25mm f/1.7 ASPH lens, Panasonic employed a diaphragm with 7 rounded blades, which has resulted in fairly nice bokeh, at least in our opinion. However, recognising that bokeh evaluation is subjective, we have provided a few examples for your perusal. The Olympus M.Zuiko Digital ED 8-25mm F4.0 Pro is a compact, lightweight and weather-sealed ultra-wide-angle to standard zoom lens for the Micro Four Thirds system. The OM System M.Zuiko Digital ED 100-400mm f/5-6.3 IS lens is a mid-range telephoto zoom that gives a 200-800mm equivalent, although with a relatively slow aperture, you do need bright sunny conditions to get the best out of the lens and camera. It’s also compatible with the Olympus MC-14 (1.4x) and MC-20 (2.0x) teleconverters if you want even more reach. Covering a 35mm-equivalent focal length range of 16-50mm and boasting surprisingly good macro performance, it shows great promise as a versatile, single-carry lens for landscape, street and travel photography. My review of the Olympus M.ZUIKO DIGITAL ED 25mm 1:1.2 PRO, the first lens in Olympus new F/1.2 Pro lineup. I tested the Olympus 25mm 1:1.2 regarding sharpness, flares, bokeh, and CAs.In our review, we especially appreciated how the smaller size of this prime lens means it’s doesn’t dwarf or overbalance even the smaller mirrorless cameras. Also, the sheer value for money here is really quite impressive – getting an effective little telephoto prime for an MFT camera at this price really can’t be sniffed at, especially with that aforementioned generous maximum aperture. Pros Panasonic continues support under its Lumix imprint, even though it's added a full-frame camera system to its catalog. It uses the Lumix G designation for its Micro Four Thirds cameras, which include mainstream models and specialty options like the tiny BGH1 video camera. With an equivalent range of 16-50mm, the Olympus M.Zuiko Digital ED 8-25mm f/4 PRO lens is a very useful wide-angle walk-around lens. As we noted in our review, it delivers the goods optically throughout its zoom range – it really is sharper than sharp – and Olympus’s ‘PRO’ designation means that build quality is also premium. It’s a lens that feels good to hold and use. Manual focusing is done in a traditional fashion, with the adequately sized focus ring mechanically coupled to the moving lens elements, although there are no hard stops at either end. Focusing is fully internal and the filter thread does not rotate on focus.

While the lens has a fair degree of barrel distortion in its optical design (which is to be expected, as the M43 system prioritizes compact size), distortion is fully corrected for, digitally, in the camera's JPEGs and/or in your Raw converter. This means straight lines will look, well, straight (see the images above the flowers for an example). The lens also shows minimal vignetting wide open and any traces of vignetting are gone by F2.8. The Olympus M.Zuiko Digital ED 8-25mm F4.0 Pro doesn't exhibit too much barrel or pincushion distortion, as you can see in the photos below. You work out a lens’ full-frame equivalent focal length by multiplying th for people with the PanLeica F1.4, I don't think it's as clear or even choosing between the 2. The 25mm F1.2 doesn't seem like it's worth double the F1.4 and it's physically bigger.If there is one area one might criticize the Olympus M.ZUIKO 25mm 1:1.2 PRO it is its behavior against bright light. If the sun is in the frame flares are very likely. Here is an extreme example: The M.Zuiko Digital ED 8-25mm F4.0 Pro lens is very well built, fully living up to the PRO designation that Olympus have given it. Weather-sealing– If you’re likely to be shooting street or landscape photography and don’t want to stop due to poor weather conditions, then look out for a lens that is weather-sealed, as this will help protect your lens, as well as your camera. Micro Four Thirds lenses: frequently asked questions FAQ: Does Micro Four Thirds have a future?

Announced in June 2011, the 25mm f1.4 became the second Leica-branded lens from Panasonic for the Micro Four Thirds system. Like the 45mm f2.8 macro lens before it, this means Leica designs the optics and Panasonic carries out the manufacturing under approval in Japan. Above: In terms of style and controls, the 8-25mm looks like other models in the Olympus Pro series, but actually becomes the first in that range to employ a retracting barrel for a reduced size during transportation.

With the lens set to its maximum aperture of f/4, there is some light fall-off in the corners, requiring you to stop down by at least 2 f-stops to completely prevent it. This wide-angle prime, a recent effort from Panasonic, is a solid addition to the kit bag of any landscape photographer using Micro Four Thirds. It impressed across the board in our testing, delivering sharp results in most shooting scenarios that we subjected it to. It’s also worth noting that this is an autofocus lens, which somewhat sets it apart in the MFT system – generally, for something this wide (18mm equivalent), your options are manual focus only. Bokeh is a word used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such as smooth / creamy / harsh etc. Finding a lens for a Micro Four Thirds camera isn't hard—there have been hundreds of different types over the years. But there are some things to take into account.
