Irix announces its long-awaited 45mm F1.4 still lens for Canon EF, Nikon F and Pentax K mounts

09 Mar

Irix has announced the details of its new 45mm F1.4 manual lens for full-frame camera systems.

The lens was originally teased as a prototype way back in 2017 at The Photography Show. Last year, a cine version of the lens was released, but the still photography version remained to be seen, until today.

The 45mm F1.4 lens is based around Irix’s Dragonfly design technology, which uses an aluminum-magnesium alloy and composite elements to create a lightweight, but sturdy design that’s weather-resistant thanks to multiple gaskets throughout the lens. The focus ring has a 140-degree throw, a focus-lock feature and offers laser-engraved markings with luminescent paint for easier viewing in low-light environments.

No launch date or pricing information is available at this time. When the 45mmm F1.4 lens does launch, it will be available for Canon EF, Nikon F and Pentax K camera systems. We have contacted Irix to request more information and will update this article accordingly if and when we receive a response.

Hasselblad’s new X-series 45mm F4 claims to be the smallest and lightest lens ever developed for digital medium-format cameras. Equally compelling is the fact that at $ 1100 it’s less than half the cost of the existing $ 2700 XCD 45mm F3.5. So what does that loss of a stop look like in use? Take a look through our sample images.

Gear of the Year 2019 – Carey’s choice: Sigma 45mm F2.8

06 Dec
Photo: Dan Bracaglia

Sigma’s 45mm F2.8 DG DN Contemporary lens is, in many ways, not a great lens for pixel-peepers. It exhibits some fringing, it isn’t particularly sharp, and it has a pretty pedestrian maximum aperture. But I really enjoy it anyway, and it’s served as a reminder that any given lens doesn’t have to be perfect to be fun.

I first got to shoot around with the 45mm F2.8 Contemporary on a trip to Japan for the release of Sigma’s fp, their staggering 35mm F1.2 Art, and the newly designed 14-24mm F2.8 Art. No surprise, the little 45 mil was easily overshadowed by its headline-grabbing brethren. But during my time on that trip, it was glued to the a7R III I was using while traveling from one locale to another. The biggest reason for that is that the lens itself is so small.

Small gear is unobtrusive and far less intimidating for subjects, and this definitely has an impact on the way I take pictures: namely, I take more pictures of people when I’m working with less intimidating gear. I also just tend to take pictures more often, as I’ll always have a smaller camera and lens combo slung over my shoulder, whereas larger gear is more likely to be tucked away in a bag when I’m not actively using it.

We’ve touched a bit on the Sigma 45mm’s image quality at the outset out of this article, but I’d like to backpedal a bit. The biggest ‘issue’ with it is uncorrected spherical aberration, essentially trading-off some sharpness for more attractive bokeh: a deliberate decision on Sigma’s part. And I have to admit that there’s something about its rendering that I find appealing. I also appreciate its very close minimum focus distance, which helps you get shallower depth-of-field than you might expect with an F2.8 aperture, though images get a bit hazy if you’re focusing very close with the aperture wide-open.

And then there’s the build quality. The 45mm Contemporary is not weather-sealed, which is a big disappointment; especially considering how well it pairs with Sigma’s fp, which is very well-sealed throughout. But the lens still has a premium feel, with its all-metal build. The focus ring is so perfectly damped that I fiddle with it all the time even though I’m exclusively an autofocus kinda guy, and the aperture ring has just the right amount of clickiness to it. Autofocus is very fast, and works well with the DFD technology in Panasonic’s S1-series of cameras.

There is room in the market for less ‘serious’ tools that are still excellent in actual use

I think my main grumble concerns the price. It’s currently still hovering around its launch price of $ 559 USD, which is unequivocally a lot of coin for a slow, non-weather-sealed prime lens that has, perhaps, a bit more optical ‘character’ than people may expect nowadays.

Sigma fp | ISO 100 | 1/125 | F8

On the other hand, I’m pleased that Sigma is making it. It’s a company with a portfolio chock-full of glass that was created with size and weight considerations taking a back seat to optical excellence. There is room in the market for smaller, lighter, less ‘serious’ photographic tools that are nonetheless engaging in actual use. That’s the type of tool the Sigma 45mm F2.8 is, and I hope it’s not the last lens of its type we see from Sigma.

Irix announces impending release of its new 45mm T1.5 cinema lens

22 Oct

Cine lens manufacturer Irix has announced the impending arrival of the Irix Cine 45mm T1.5, its latest full-frame cinema lens.

This new lens marks the third full-frame cinema lens Irix has made specifically for shooting at up to 8K resolution. Irix says the 45mm T1.5 is ‘based on a completely new [11 elements in 9 groups] optical design which includes four elements made of high refraction glass, one extra-low dispersion lens and one aspherical lens’ and delivers ‘ultra-low’ 0.5-percent distortion.

The nine-blade aperture diaphragm ranges from T1.5 to T22 and the lens features ‘practically no focus breathing,’ according to Irix. Other features include a 95mm front filter thread on the housing of the lens, another 86mm built-in filter thread and a reversible lens hood that’s attached via magnets, which Irix teases will work with ‘future accessories.’

The gears are standardized 0.8 pitch mod cine gears and the lens, which is constructed of a magnesium-aluminum alloy is sealed. Irix doesn’t specify what the lens should be able to handle, other than saying it’s ‘prepared for all weather conditions.’

The Irix Cine 45mm T1.5 will be available in Canon EF, Sony E, MFT and Arri PL mounts. Pricing and availability ‘will be announced soon.’

Press Release

Irix Cine 45mm T1.5 — into the art of cinematography

Irix expands its offer of cinematographic lenses with the new full-frame 45mm T1.5.

Irix, the manufacturer of high-class optics, expands its Cine line by introducing the new 45mm T1.5 lens. This new model is the third full frame cinematographic lens designed for shooting with Ultra HD 8K cinema cameras. The Irix 45mm T1.5 is based on a completely new optical design which includes four elements made of high refraction glass, one extra-low dispersion lens and one aspherical lens. 11 elements in 9 groups deliver crisp details, vibrant colors and an ultra-low – 0,5% distortion. The circular 9-blade iris ensures a pleasant background blur and a smooth adjustment of the T- number from 1.5 to 22. With practically no focus breathing, the Irix Cine 45mm T1.5 is the perfect lens for filming scenes with a natural character.

Press release October 21st, 2019 — Irix Cinematic Design

The 45mm T1.5 is the third lens in the Irix Cine line which stands for a perfect combination of advanced technology and modern design. A good example of the Irix smart design is the front housing element which has a diameter of 95mm and a built-in 86mm filter thread. It also provides a magnetic mount for the reversible lens hood and for future Irix Cine accessories.

This synergy is also visible in the shape of the geared rings which have been integrated into the lens housing. The convenience of operating by hand and full compatibility with follow focus systems was a priority in the external design of the lens. You can use any follow focus system you like and position it wherever you want to thanks to a special rotating adaptive ring design. The adaptive ring can be adjusted to any desired position and expose the geared ring to couple with follow focus systems.

The Irix Cine line has been carefully deliberated from the start. The focus and aperture rings of all the lenses are aligned at the same height and have the same rotation angle. With the exception of the Irix

150mm T3.0 Macro 1:1, where a longer 270 degrees focus throw is necessary, the rest of the Irix Cine range lenses have ring rotations of 180 degrees for the focus ring and 75 degrees for the aperture ring.

Ready to shoot in any weather conditions

A high-class cinematic lens must work in any atmospheric condition. No matter if you are shooting on burning sand in the Sahara Desert or on the frozen peaks of the Himalayas – the Irix 45mm T1.5 is prepared to not only face it, but also to capture the best image possible. Every time. Enjoy your lens’ reliable construction with rubber seals placed in all the crucial points to ensure protection against rain or dust. Now, you can film anytime, anywhere – and seize the wondrous power of nature.

Your comfort is important! Focus and aperture marks are laser engraved and filled with UV paint. This makes them visible, even in low-light environments.

Versatility and compact in size

Irix Cine lenses are some of the most compact and lightest film lenses covering the full frame format. The housing is made of a lightweight and impact-resistant aluminum-magnesium alloy which has been successfully used and tested in the Irix Blackstone still lenses. Thanks to the low weight (every Irix Cine lens weighs about 1.1 kilograms / 2,4lbs), they can be used on smaller cameras on handheld rigs or stabilizers as well as on professional setups. In order to achieve greater comfort while working with follow focus systems, the Irix Cine lenses are equipped with a lens support foot. Depending on your needs, this support foot can be attached to the lower or upper part of the lens.

Key features of the Irix Cine 45mm T1.5 lens:

  • Mid-range focal length with field of view 51,4°

  • Suitable for shooting with Ultra HD 8K resolution cameras

  • High-quality optical elements – 11 elements in 9 groups. HR, XLD, ASP produced in

    Japan

Sigma 45mm f/2.8 Lens for Sony Review

08 Oct

The post Sigma 45mm f/2.8 Lens for Sony Review appeared first on Digital Photography School. It was authored by Suzi Pratt.

The Sigma 45mm f/2.8 DG DN (sony, Leica) is the latest addition to Sigma’s Contemporary lens line. Launched in July 2019, this lens is available as Sony E-mount or Leica L-mount. The latter mount is of particular interest as the new L-mount is compatible with Panasonic and Leica full-frame cameras, plus Sigma’s own forthcoming L-mount mirrorless cameras. I got my hands on an E-mount version and tested the lens with my Sony A7RIII. Here are my thoughts.

Sigma 45mm f/2.8 Lens for Sony E Mount

Specs

The Sigma 45mm f/2.8 lens has a maximum aperture of f/2.8, which may be a disappointment for photographers used to having at least an f/1.8 on their prime lenses. It also is a fairly expensive lens given its $ 549 price tag. However, this lens makes amends when it comes to size and the build quality.

Size

Compared to other Sigma prime lenses such as the Sigma 35mm f/1.4 Art (Nikon, Canon, Sony), this lens is significantly smaller and more lightweight. It weighs 7.5 ounces (half of the aforementioned 35mm) and comes in at less than 2-inches long. This makes the 45mm much more portable and discreet when compared to Sigma’s other Art lens primes that all have an f/1.4 aperture, but are significantly larger and heavier.

This compact size is closer to that of the Canon 50mm f/1.8 and 40mm f/2.8 pancake lens. Both were my longtime favorite prime lenses when I shot with Canon DSLRs. The beauty about this size is that it feels very balanced when attached to a full-frame camera, whether it be my old Canon 5D Mark III or my new Sony A7RIII. With that said, this lens puzzles me when I compare it to other similar lenses that I’ve owned.

Build quality

It’s hard to ignore the design of this lens, which is both visually eye-catching and functional. There are two physical rings – the outermost ring controls the focus and the innermost ring selects the aperture, similar to how a Fujifilm lens performs. Choosing the aperture via the lens can take some getting used to, but it’s a wonderful way to interact with your camera. There’s also a switch to toggle autofocus or manual focus. The lens itself is made mostly of metal, and it includes a lens hood that is also made of metal. There is also weather sealing on the mount of the lens to keep dust and dirt at a minimal.

Shooting experience

45mm is an interesting focal length. It sits comfortably between two of the most popular focal lengths out there: the 35mm and 50mm. Not too wide or too narrow, 45mm gives you a range that feels natural, yet intentional. Autofocus on this lens is fast, accurate, and very quiet thanks to a fast-stepping motor.

If you shoot on a Sony full-frame mirrorless camera, you may also be familiar with the feature of flipping between shooting in full-frame and APS-C mode. While the latter does crop and shrink your images, it gives you the ability to shoot at a slightly zoomed-in focal length. This, in turn, gives you at least two focal lengths to shoot from, and it is one of my favorite features of my Sony A7RIII.

Image quality

The images captured by the Sigma 45mm f/2.8 lens result in very consistent color, tones, and sharpness. This lens has a rounded seven-blade diaphragm that renders a smooth, shallow depth of field. There is a minimum focusing distance of 9.4 inches, giving this 45mm decent macro capabilities.

In Conclusion

Overall, I had a very positive experience shooting with this Sigma 45mm f/2.8 lens. The compact size complemented the Sony A7RIII perfectly, making it a very portable unit. I usually have a 24-70mm f/2.8 or 55mm f/1.8 glued to my camera when shooting in low lighting scenarios. Thus, the 45mm’s f/2.8 aperture did not hinder me much. However, there is something to be said about having a faster aperture, especially in low light conditions.

If you enjoy shooting with a versatile prime lens that is reasonably fast but very portable, this Sigma 45mm f/2.8 lens might be the lens for you.

What are your first impressions of the Sigma 45mm f/2.8 lens? Would you purchase it? Why or why not?

Rokinon announces pricing, availability of its new 45mm F1.8 lens for Sony full-frame cameras

13 May

Rokinon, known in other markets as Samyang and Bowers, has announced the pricing and availability of its new AF 45mm F1.8 lens for Sony full-frame camera systems.

The lens, which Rokinon calls ‘tiny but premium’ is the latest in its ‘Tiny Series’ lens lineup. The optical construction consists of seven elements in six groups, including two aspherical elements and one extra-low dispersion element. Certain elements inside the design also feature Rokinon’s ‘Ultra Multi-Coating,’ which is said to reduct flaring and ghosting.

Inside, it features an autofocus motor for Sony camera systems, a nine-blade aperture diaphragm and an aperture range between F1.8 and F22.

While the lens was designed for full-frame Sony mirrorless cameras, it can also be used with Sony APS-C models where it ends up being a 67.5mm equivalent focal length lens. The lens measures in at 61.8mm (2.43in) by 56.1mm (2.21in) and weighs just 162g (5.7oz).

The Rokinon AF 45mm F1.8 lens is available to pre-order for $ 399 on B&H and has a suggested retail price of £349.99 in the UK. Orders are expected to ship at the end of May 2019.
