QHY has confirmed they're releasing a full frame mono cmos camera.  It's called the QHY600 and uses an IMX455 sensor.  They will be displaying it at NEAF.  It seems to use the same architecture as the IMX411 and IMX461 sensors (which QHY is also showing at NEAF).  3.76um pixel size, 61mp, 42mm diagonal.  It has a rolling shutter (preferable).  I have a feeling things didn't work out with the IMX342 and GMAX0806 because they use global shutters.   

 

Here's the sony sensor "Roadmap" for those interested:

This is great news, looking for a good mono sensor for my soon to arrive CFF185. Unless it costs 50k ...

[chadrian84]

Rumor has it the 150MP IMX411 sensor (just the sensor) will cost 9k, and the 100MP IMX461 will cost 7k.  A reasonable estimate would be 5k for the IMX455 sensor.  Figure another 1-2k for the cost of the camera and it should be well under 10k.

Here's the sony sensor "Roadmap" for those interested:

 

I asked on the QHY forums about a week or so ago about their plans on possibly using the sensor in the Nikon D850 (IMX309) in a one shot like their QHY367C, and today just saw Mr. Q's response regarding the QHY600 in both a color and mono version. I have the QHY367C on backorder right now, and now am wondering if I should cancel and wait for the 600 color version? Do they usually give projected msrp pricing at NEAF on new products like this? If the color 600 is like double the price of the 367C then I'd just get the 367C, but if its only a thousand or two more that might be doable.

Awesome news! I am keenly interested, but very nervous about the price. The specs of this sensor really feel like a goldilocks camera is potentially here. 

[cfosterstars]

What about an ASP-C Mono camera?

Thing I'm nervous about besides the price is 60 megapixels on whats not much bigger than a full frame sensor. In the daylight photography world of which I'm intimately connected .. 60 megapixels is medium format territory, it will be interesting to see what this sensor does on the new rumored Nikon DSLR that supposedly will use this sensor.

The cost of these cameras are a bit out of control

The big thing about it is the mono option. And, you can always bin/downsample, which 2x2 would still deliver 15 megapixels.

Exactly. Also I thought these new sensors had a higher dynamic range. This could equate to needing less subs, in the way that CCD cameras work. 

[Jon Rista]

I found some details on this sensor, and some others. It has IMMENSE dynamic range:

 

https://www.sonyrumo...-imx551-sensor/

 

A 49000e- FWC and 2.263e- read noise for 14.45 stops of dynamic range. The IMX551 is even more insane, with 14.9 stops of DR.

[chadrian84]

QHY said today the price will be "much higher" and a "major price difference" from the QHY367C.  That's not a very good sign since the QHY367C sells for $4400.  

[motab]

It’s around twice the cost of a 367C. Don’t think I have that kind of cash to blow on QHY’s recent announcement and would need a second mortgage to pair it up with suitable filters and optics. I guess we’ll never get a decent mono APS-C sensor.

Yeah I saw that .. $8800.00 is outta my league ..... so helloooooo QHY367C and mosaics 

[cfosterstars]

Any specs on the IMX 571 ASP-C sensor? Does it come in mono? APS-C should be much less than a full frame.

Are you speculating or did you get that estimate from a good source?  I have a number I'm willing to pay for FF mono CMOS.  Unfortunately, "around twice the cost of the 367C" is quite a bit higher than I'll go.

It doesn't look like Sony offers the IMX 571 in mono. --- "There's always next year."

Not to sound salty, but what the hell?


Too darn expensive

Nah .. we don't have the exact amount right now, but when I asked Mr. Q yesterday if they were going to keep the QHY367C in the line up he said 'yes as the 600 is significantly more money than the 367C' So yeah how do we quantify one man's significantly more than anothers .. it would be nice if that equated to 1k more .. that I could handle .. but I'm already prepared for that 7/8k figure, but if wrong will be pretty excited  I'm sure those higher res ones will be in the Hasseblad/Phase One bracket .. basically unobtanium  lol. Ok where'd I put my hyper tank .....

I was hoping the IMX342 sensor could make a good mono APS-C camera. It doesn't look like it is in the plans from the response I got on my QHY facebook post. I think there would be a lot of demand for an APS-C mono cmos camera. Being able to use 36 mm filters would keep overall cost down for the setup. I sure hope we will see something in the APS-C mono before too long. 16 bit would be great with large pixels and deep wells.

 

I went with an OSC (ASI094MC) for full-frame for now. I already have a full set of 36mm Astrodons. Having to buy 50mm or maybe even 65mm filters is just too much for me right now. At least OSC is easy. Now, if they could just build a huge sensor with a bayer matrix with Ha, Oiii, and Sii...ha, ha...won't hold my breath!

What about an APS-H Mono camera. 

 

KAF-16200. Been saying this for way too long now. Incredible sensor in good packages for a good price. 

[rms40]

I understand that 36mm filters will vignette with the KAF-16200 sensor. It does look like a good ccd sensor.

Is this the same sensor? They are claiming 16bit. Or am I missing the definition of dynamic range... wouldn't be the first time.

Bit depth and dynamic range are not the same thing. Dynamic range is the full well capacity/saturation limit divided by the read noise. DR may be higher or lower than the bit depth, which is the precision at which the ADC unit reads out at.
