Fuji patents evolution of the “real-image zoom optical viewfinder”.

 photo ovfzoom_zps0188fb01.jpg

This is one of the (many) Fujifilm patents you can check out at freepatentsonline here (PDF file here). It was published back in April (04/29/2014), Filing Date or the Patent: 01/02/2014

It seems to be an evolution of the “Real-image zoom viewfinder” already present in the X20 viewfinder. There is plenty of technical stuff to read at freepatentsonline, but petapixel sums it up saying that “the viewfinder would be able to optically zoom in synchronization with the varying focal length of a zoom lens.” And, at least looking at the image of the patent, this viewfinder should find its way into future compact Fuji Point&Shoot cameras.

But what’s the advantage of this specific “real-image viewfinder” compared to the one of the X20 (which delivers 85% coverage and a 20° horizontal apparent field of view)? Well, I do not know, and it must be hidden somewhere in the very complicated description of the patent.

So will maybe the X30 feature an upgraded “real-image zoom optical viewfinder”? That’s the question I’ll now send directly to our sources ;-)

But it’s good to see that Fuji continues to work on the OVF technology. It’s definitely a good news for OVF lovers. However, no OVF in the world will give you the possibility to see in real-time how your final shot will be (WYSIWYG), which is very useful, especially when you have to act fast and there is not the time to take a shot, check the result on the LCD, change the exposure, take another shot, check the image again, make adjustments and so on. With an EVF you look through the viewfinder, turn the dial, see immediately the result in the EVF… and “click“.

But what do you think? Do you prefer the EVF or the OVF? 2 alternatives, one answer. And feel free to list your PROS and CONS for a OVF or EVF in the comments.

Oh, and I know, a hybrid viewfinder would make us all happy. So, dear Fuji, don’t forget it in the X-PRO2 :-)

Between the X-T20 and the X-E3, I'd buy the...

And just for fun. Here is how Fuji explains the “real-image zoom viewfinder“. It’s all one sentence, so be concentrated:

“A real-image zoom viewfinder substantially consisting of, in order from an object side, a variable-magnification objective lens system having a positive refractive power, an erect optical system, and an eyepiece lens system having a positive refractive power, wherein the variable-magnification objective lens system substantially consisting of, in order from the object side, a first lens group that includes a first lens having a negative refractive power and a reflective member arranged in this order from the object side and is fixed during magnification change, a second lens group that has a positive refractive power and is moved during magnification change, and a third lens group that has a positive refractive power and is moved during magnification change, the erect optical system has at least one reflective surface for converting an inverted image formed by the variable-magnification objective lens system into an erect image and is fixed during magnification change, the eyepiece lens system has a positive refractive power and is fixed during magnification change, and conditional expressions (1), (2A) and (3) below are satisfied at the same time:
1.5<U2/U1<3.0 (1),
1.76≦|f2/f1|<2.0 (2A) and
1.0<f3/f2<5.0 (3), where U1 is a distance from an object-side lens surface of the first lens to a most object-side lens surface in the second lens group along an optical axis in a state where zoom setting is set at a telephoto end, U2 is a difference between the distance from the object-side lens surface of the first lens to the most object-side lens surface in the second lens group along the optical axis in a state where the zoom setting is set at the telephoto end and a distance from the object-side lens surface of the first lens to a most image-side lens surface in the third lens group along the optical axis in a state where the zoom setting is set at a wide-angle end, f1 is a focal length of the first lens group, f2 is a focal length of the second lens group, and f3 is a focal length of the third lens group.”

Patent: new color filter, also for organic sensor!

The innovation continues. Fujifilm is working hard on the new organic sensor. Will this be the sensor of the X-PRO2? I still don’t know it. In the meantime check out the patent for new color filters giving better color reproducibility and less noise, applicable also to the organic sensor, at freepatentsonline.com.

Organic sensor or not, looking at the various polls shared here on FR, the majority of you prefer an APS-C sensor over a Full Frame sensor.

Patent: fast super telephoto XF zoom lens 85-300mm f/2.7 – 3.7

 photo fuji_x_85_300mm_zps879795d7.jpg

Mirrorlessrumors spotted a new Fuji patent. The Fuji patent, published here, shows a fast super telephoto zoom lens, the XF 85-300 f/2.7-3.7. It’s a patent, so the figures could change. Also the XF 56mm (best seller at AmazonUS) changed from f1.4 to f/1.2 on my birthday last year (April 17th).

A new source told us previously here that the lens would be a 120-400 lens (equivalent or not, the source did not specify).

EU-ORDERS: Luzu: “Choose UPS for international delivery, their option “UPS Super Saver” for around 45$ is the cheapest anyways. If you “pay on delivery”, UPS will handle all the customs work for you and deliver the item home to you where you pay the customs costs directly to the mailman. No going to customs office needed! Declaration of the deliveries from B&H is made very professionally by them and UPS, so I guess German customs are seldom stopping them. I already ordered two lenses this way (the 27mm and the 55-200mm) without problems! Btw.: The delivery is by plane and super fast … around two days only!

Fuji Patent: X-Trans evolution? Sensor with enlarged green pixels!

 photo egami_zpsd88ced24.png

Fujifilm has been at the “forefront of sensor innovation” thanks to the X-Trans sensor (technology of the year award 2012 at imaging-resource here). The company is also working with Panasonic on the organic sensor (press release). And if I remember well, a Fuji manager said that Fujifilm wants to have the best sensor on the market, focussing more and more on the pixel quality rather than simply on pixel quantity.

And indeed, Fujifilm is not resting on its laurels: egami spotted one more Fuji sensor patent here (translation).

„Fujifilm is different pixel size by color imaging element of the is pending. The human eye is sensitive to luminance noise than the color noise, it is possible to improve the high sensitivity performance and practical to increase the pixel size of the white and green.”

Looks like an X-Trans evolution to me.

Fuji’s birthday tomorrow

NOTE: Tomorrow it’s Fuji’s brithday! According to the information I have, the X-T1 should be announced on the 28th. But I wouldn’t be surprised to see other products coming on the 20th in order to celebrate Fuji’s birthday. So stay tuned, I’ll keep you updated with the latest news.

enjoy your Sunday,

organic sensor patent

A couple of time ago Fuji and Panasonic announced a new partnership and said that they are developing the first organic sensor together. The new technology promises among the others “Industry’s highest dynamic range of 88dB”, “higher sensitivity than conventional sensors” and “ faithful color reproduction“. Now at freepatentsonline.com you can read 19 pages of technical explanation how this works.

Fujifilm purchasing Kodak patents

kodak

 

As petapixel reports, Kodak sold valuable imaging patents for $525 million to various companies. “The deal involves more than 1,100 patents related to the capturing, manipulating, and sharing of digital photographs.” Fujifilm is part of the consortium that purchased Kodak patents.

Although this sale leaves Kodak empty-handed in terms of digital imaging patents, the company is still loaded with patents related to other areas of its businessNow that the sale has been completed, Kodak is free to move forward with its plans of conquering the world of commercial printing.

New Fuji patent discloses a phase detection pixel technology

We know well that it AF speed is not exactly one of the most impressive features of the X cameras. But Fuji seems to working on some innovative solutions for the future. The Japanese website Egami (translation here) spotted that new patent describing an on sensor phase detection system. The interesting news here is they found a way to allow such a feature without the use of extra Phase detection AF pixels!

Let’s hope this is coming with the next X camera…

Sigma Japan Suspends Orders for Entire DC DN Lens Lineup

Sigma Japan just announced the suspension of orders for the following DC DN APS-C lenses:

So the entire APS-C lineup orders are on hold in Japan. I don’t know if this is valid for the rest of the world too, but for now they seem to be still available for order at stores like BHphoto.

The motivation they give is strange: the demand exceeds Sigma’s expectations.

So I wonder what happened. If all of a sudden demand for Sigma APS-C lenses rose strongly, or if maybe Sigma’s production capacity dropped for reasons we do not know.
