To compete with the Tamron 35-150mm F/2-2.8 Di III VXD lens, Sigma is now working on a 50-140mm lens with a constant aperture of f/2.8. It may have an affordable price tag and they are also working on a new generation of 70-200mm f/2.8 lens.
We, already have Sigma lenses like 50-100mm F1.8, Sigma has filed a patent for a 50-140mm F1.8 Lens. In General whenever a camera maker files a patent for a new product, it roughly they take 1-2 years to make it an official. We do believe Sigma will put extra effort to make it faster.
Kind Code: A1 A compact image forming optical system having a small open F value over the entire zoom range is provided.
2. Description of the Related Art
In recent years, a so-called mirrorless camera, which eliminates a quick-return mirror that is arranged between an imaging optical system and an imaging device and guides light rays to a finder optical system, has become popular. Since the body of the mirrorless camera has been downsized by eliminating the mirror, downsizing of the imaging optical system is required accordingly. Also, there is a demand for a large aperture zoom lens with a small open F-number over the entire zoom range.
[0004]
Patent Document 1 discloses a positive lead type zoom lens having a bright open F number of about 2.8 and having a lens group closest to the object side fixed with respect to an image plane during zooming. Since the optical total length does not change, convenience and robustness are high, but there is a problem that the size of the imaging optical system is large. Patent Document 2 discloses a positive lead type zoom lens having a bright open F number of about 2.8 and a shortened total optical length at the wide-angle end. However, since many lens groups with large diameters that move during zooming are arranged on the image side of the aperture stop, the mechanism required for zooming is large, and the size of the lens barrel in the radial direction is large. .
SUMMARY OF THE INVENTION It is an object of the present invention to provide a compact image forming optical system with a small open F value over the entire zoom range .
Today, Phase One announced an overpriced $65,000 for a camera with a 150-megapixel medium format sensor made by Sony and a 23mm F5.6 (14.9mm, F3.6 equiv.) fixed lens. If the sensor was made by Phase One and was exclusive to that camera, even in that particular situation the $60k+ isn’t justified for a camera body with a lens.
However, we all know that after a while, the same sensor will arrive inside the body of a Hasselblad X2D 150c or X3D 150c camera or the Fuji medium format camera under the Fuji GFX 150 series. So there is a high probability that we will see that particular sensor in upcoming years in many different cameras.
These camera makers like Fuji and Hasselblad will hardly ask you for $10,000 or even less. So the big question is: who will pay that much amount to Phase One? This is the right time for them to learn from others like Fuji and Hasselblad to introduce a stripped-down line of their exclusive series in the competition.
Camera with Higher Price tag NEVER SALES Well, their CONSUMER BASE IS VERY LIMITED to FEW People
Some Budget Medium Format Cameras
But, one Camera maker shows some effort like Hasselblad did with their X Series, and puts the same sensor under an affordable Mirrorless body, and it goes in the TOP seller chart
Fuji GFX 100S is more popular among users and among the TOP selling camera @ B&H Store
So, finally, Canon has discontinued its G1X Mark 3 camera. What can we expect next from Canon? Will they release a new G1X Mark 4 camera or, by looking at the current trend, will they release a new V series camera for their consumer base? Let’s hope for the best
Image of Canon G1 X Mark II [Older Version with 1.5 inch CMOS Sensor]
The G1X Mark III camera was announced back in 2017. It used a 24 DPAF sensor of Canon 200D Mark II and Canon M50 II and Digic 8 image processor. Compared to the Mark 2 camera, which used a 1.5-inch sensor, the Mark 3 used an APS-C sensor. Despite this fact, the size of the Mark 3 was smaller than the Mark 2.
Canon’s Next Move: G1X Mark 4 or V Series?
Now again, we have high hopes after the discontinuation of the G1 X Mark 3 camera. The production lines are clear and the stockpiles are almost clear, so we expect a camera’s arrival under the V series. So, the big question next camera from Canon coming under the V range is APS-C Compact or a Mirrorless camera. Let’s hope for the best and see what arrives next.
Now you can use your Sony lenses directly on Nikon Z Mount-based mirrorless cameras with the help of the new Fotodiox autofocus adapter. The lens adapter works almost perfectly for taking still pictures and you can control the aperture of the lens electronically too. The autofocus is perfectly reliable for still shooting.
However, if you’re into video, then it is probably not recommended to get into this mess. After looking at the results of its tests, I have concluded that it doesn’t work perfectly for videos. Specifically, if you have third-party lenses, then you will feel synchronization issues there several times while doing autofocus for video.
Sony Alpha E-Mount Lenses to Nikon Z-Mount Mirrorless Cameras; infinity focus or beyond guaranteed
Built-in FUSION technology enables electronic communication and control between lens and camera
Restores automated functions on most lenses such as auto-focus, aperture control, image stabilization and more with compatible lenses
Precise fit and solid all-metal construction with chrome plated brass mounts for secure and solid fit; lens has no play, gap or wiggling when mounted on adapter and no adjustments required
Limited 2-Year Manufacturer Warranty
So the adapter is good for still shooters but not for video.

Yesterday, Nikon announced two different lenses. One is the Nikkor Z 70-200mm f/2.8 and the other is the Nikkor Z 180-600mm f/5.6-6.3 VR. The main attraction right now is Nikon’s open Lens Mount policy and they are now releasing a series of lenses at the available price range. Now, why I am talking about an open lens mount? Since one of the lenses among the two is made by Nikon itself and the other (70-180 F2.8) is re-branded as NIKKOR Lens but it’s actually made by Tamron.
Nikon’s Latest Lenses announcement.
The latest edition is the Tamron branded 70-180mm lens. The most attractive thing about this lens is its price: a 70-200mm f/2.8, which is near impossible for any camera brand to offer. Another thing that surprised me, even more than its price, is the use of a stepper motor. Generally, Tamron uses a linear actuator motor in their 70-180mm lens. Stepper motors are generally considered to be more accurate than actuator motors, but you have to compensate with speed.
The Other lens in the set is the Nikon NIKKOR Z 180-600mm f/5.6-6.3 VR Lens (Nikon Z), its covers a vast range of 600mm but has variable aperture. Being a Nikkor homemade Lens, I have high hopes for the lens and its sharpness and overall performance.
So let’s have a look at the teardown of the ultra-popular Fuji X-H2 camera done by IRrecams.de. And as a disclaimer, do not try this yourself if you have some issues with the Fuji X-H2 or any other camera you have in your hand. Don’t attempt these things by just looking at images or videos. It’s better to visit your nearest service center to have it done professionally.
