From

The 10-25mm is 2.5x zoom and the 25-62.5mm would be 2.5 zoom also. The range would be equivalent to 20-125mm in full frame considering the two lenses, enough for all film work.

If 25-62.5 is difficult to build, maybe 30-60mm 1.7 would be great also

Weighing in at less than 7 oz (192 g), the new lightweight FE 50mm F1.8 “normal” prime lens (model SEL50F18F) delivers an outstanding blend of performance, compactness and value, making it a perfect choice for hobbyist photographers and videographers looking to experience the benefits of a wide aperture prime lens at an attainable cost.

The lens features a new optical design with an aspherical element that effectively compensates for all forms of aberration, resulting in beautiful, crisp imagery. Additionally, it has a circular aperture with a maximum of F1.8, producing beautiful ‘bokeh’ in images that allows the subject to stand out against a smoothly defocused background. For extended durability, the new prime lens is built with a solid metal mount.

The new FE 50mm F1.8 prime lens will also be available in May for about $250 US and $350 CA, respectively.

For those interested in expanding their X-T200 tool kit, the new FUJINON XC 35mm F2 lens gives an equivalent to 52mm field of view on 35mm format. Weighing just 130g and measuring 46.5mm in length, this new prime lens has nine elements, including two aspherical lens elements in six groups, which work to produce sharp and crisp images with creamy bokeh. AF operation is quick and near silent thanks to the use of an internal focus system and a stepping motor, which is used to drive the focusing elements quickly and accurately.

This new ZEISS® Distagon T* FE 35mm F1.4 ZA full-frame wide angle prime showcases legendary ZEISS® optical performance in a compact design.
With a minimum focusing distance of approximately 12 inches, the ZEISS® Distagon T* FE 35mm F1.4 is the first E-mount lens to feature an exceptionally fast aperture of F1.4. The lens has a 9-bladed circular aperture, which makes it a superior choice for creating smooth bokeh (defocus) during portrait shooting. It also performs extremely well in low-light shooting scenarios or for simple everyday photographs.

The new 35mm prime lens produces stunning corner-to-corner sharpness – even at maximum aperture – thanks to its advanced optical design with 3 aspherical elements including one Sony advanced aspherical element and a 9-bladed circular aperture. It also features ZEISS® T* coating that suppresses flare and ghosting for natural color reproduction and excellent contrast.

Additionally, the lens has a Direct Drive SSM (DDSSM) system that enables whisper-quiet precision focusing, even at the shallowest depth of field. A dedicated aperture ring can be set for smooth, continuous operation – ideal for movie-makers – or with click-stops to provide tactile feedback when shooting still images. The ZEISS® Distagon T* FE 35mm F1.4 is also dust and moisture resistant design for reliable operation when shooting outdoors.

FUJIFILM Corporation has unveiled the latest plans to add to its Family of GF Lenses, designed exclusively for the GFX Mirrorless Camera System; which is equipped with Fujifilm's large format (43.8mm x 32.9mm) image sensor, an imaging surface approximately 1.7 times the size of 35mm full-frame sensors*1.

Bringing the eventual total to 13 lenses, this expanded GF lens lineup will accommodate even broader shooting categories and diverse shooting styles.

More about the two lenses recently added to the GF lens development roadmap:

FUJINON GF30mmF3.5 R WR: An impressive, wide-angle, prime lens. This wide angle 30mm lens is an equivalent 24mm focal length in the 35mm film format and is a perfect solution for landscape photography.

This lens will be a slim, compact, and lightweight lens offering incredible resolving power for high-resolution imaging sensors.

FUJINON GF80mmF1.7 R WR: A unique, wide-aperture, standard lens. A standard 80mm lens with an equivalent focal length of 63mm in the 35mm film format, which is incredibly suitable for portraiture and making images in low-light conditions.

This will be the lens with the widest aperture among GF lenses and be an incredible solution for portrait photographers who want beautiful, creamy bokeh with their GFX System Cameras.

This compact and lightweight lens will have a wider angle of view than the highly popular GF100mmF2 R LM WR and deliver the same level of incredible image quality.

Today, Nikon Inc. announced the fast, wide- angle NIKKOR Z 24mm f/1.8 S, the latest addition to the ever-expanding NIKKOR Z lineup of lenses. The 24mm f/1.8 S is optimized for capturing everything from cityscapes to environmental portraits and is built to take advantage of Nikon's large Z-mount, delivering the ultimate combination of fast, bright and sharp performance in nearly all lighting conditions.

"The NIKKOR Z 24mm f/1.8 S continues our commitment to offering exciting prime lenses to Nikon Z 7 and Z 6 users, while also providing exceptional level of quality achieved by the S-Line of NIKKOR Z lenses," said Jay Vannatter, Executive Vice President, Nikon Inc. "The combination of wide-angle perspective and a fast f/1.8 aperture is optimal for all types of photography including landscapes, making the NIKKOR Z 24mm f/1.8 S a must-have lens to unleash the full potential of the Nikon Z series."

The NIKKOR Z 24mm f/1.8 S -- A Storyteller's Dream Lens:

The NIKKOR Z 24mm f/1.8 S joins the S-Line of high-performance NIKKOR Z lenses, giving creators an essential focal length to add to their kit of fast prime Z-mount lenses. The lens takes advantage of the most advanced NIKKOR technologies to deliver optical superiority, exceptional sharpness, beautiful bokeh and high-resolution across the entire frame, even at maximum aperture.

The new NIKKOR Z 24mm f/1.8 S was designed for photographers and videographers looking to capture gorgeous wide-angle landscapes or vivid street photography, a travel adventure or a stunning starscape. For videographers and content creators, this popular focal length is a staple for production due to its natural perspective. Thanks to the advantages of the lens' bright and fast f/1.8 maximum aperture along with the wider Z-mount, Nikon Z series users can capture exceptionally sharp images in dimly lit settings, with a lens that's ideal for nighttime shooting and astrophotography.

The NIKKOR Z 24mm f/1.8 S features 9 rounded aperture blades, allowing users to capture beautifully circular bokeh that adds a level of dimensionality to help capture compelling content. Users can confidently explore their creative potential in nearly any landscape thanks to the lens' reliable dust and drip resistant design, ideal for tough weather conditions. The lens construction also consists of four Aspherical Lens Elements and one Extra-Low Dispersion (ED) glass element to combat aberration, while Nikon's patented Nano Crystal Coat helps eliminate ghosting and flare. The 24mm f/1.8 S is further equipped with Nikon's Multi-Focusing System, which uses two AF drives in tandem to deliver superior resolving power and achieve fast and accurate autofocus, even at minimum focus distance.

In addition to achieving the top-notch image quality that storytellers and content creators have come to expect from the S-Line of NIKKOR Z lenses, the NIKKOR Z 24mm f/1.8 S is also optimized for video capture. As a popular cinematic focal length, the 24mm f/1.8 S will be a welcome addition to Z series shooters' arsenals, boasting near-silent stepping motors for ultra-quiet performance, reduced focus breathing, a customizable control ring for smooth control of aperture and exposure compensation and the ability to take advantage of the in-camera 5-axis VR + eVR of the Nikon Z series cameras.

Price and Availability

The NIKKOR Z 24mm f/1.8 S will be available in mid to late October 2019 at a suggested retail price (SRP) of $999.95. For more information on the latest Nikon products, including the new NIKKOR Z 24mm f/1.8 S and the full Nikon Z mount system, please visit www.nikonusa.com.

Dedicated video lenses usually feature stepless aperture to allow for smooth adjustment of exposure. Most still photography lenses, in contrast, feature stepped aperture adjustment. This article demonstrates how to "de-click" Canon FD lenses to get stepless aperture.

Before you continue, note that

1. De-clicking is easy. All you need to do is to unscrew the rear and take out one or two things.
2. The process will not introduce dust into your lens---the optical assembly is sealed in one piece inside the lens.
3. There is a "cheat" that gives you continuous aperture adjustment without the hassle of opening up the lens. All you need to do is set your lens to the smallest aperture, then turn the ring on the FD adapter. The downside of this cheat is you do not have any indication of which f-stop you are at.

With that in mind, if you still believe de-clicking is useful---and I personally do find that being the case---here is a quick demonstration on how to do so.

1. Take apart the lens from the rear and remove parts that cause un-smooth movement

2. Remove the piston

If instead your FD lens locks with a rotating metal ring, you will need to remove the two ball bearings inside the aperture ring.

3. Removing the spring holding the aperture selector

4. Linking the aperture ring to the aperture diaphragm

If your FD lens locks with a rotating metal ring, you will be lopping around the coupling fork instead:

5. Re-assemble the lens. It's done!
