Nice lens, I wonder if it performs better than the Sony equivalent?

On article CP+ 2018: Hands-on with Tokina's 50mm F1.4 and 20mm F2 (73 comments in total)

With Tamron and especially Sigma offering all the bells and whistles in the third party lens department, what advantage does Tokina offer over them? Due to their small size I suppose they always seem to be a little behind the curve.

Elliot H: a very silly lens

A no-compromise lens too far? I think so...the 105mm is probably superb optically but just too massive for a portrait lens. It seems unwieldy to work with handheld.

Shlomo Goldwasser: "It's not totally clear-cut who this camera is for."

Given its price and feature set it is directly competing with the Panasonic G9 and Olympus OMD-EM1mkii, as well as the Nikon D500. While the x-h1 has not been tested yet, its spec sheet and feature set are not as impressive as the competition.

This camera looks like fanservice.

Shlomo Goldwasser but that means the sensor has to move twice the distance vertically or horizontally. Can current IBIS systems, like the one used in the X-H1 do that?

Zdman: Before everyone gets excited Invisage were pioneers of this technology and even managed to get a mass prodcution partner. So what happened? Well there a a few little disadvatages not mentioned here. First reset noise (Ktc) and dark current which was more than a magnitude higher than CMOS. The only published reading was 600 electrons per second dark current for a 1.5um pixel. Even with a larger full well thats probably 4 bits of noise after a second. Then there's non uniformity due to an inability to get a consistent layer. Finally there are lifetimes issues so don't expect the blue dots to last as long as red dots which will change the long term colour accuracy. We might even see sensor burn in with long time lapeses.

otto k thanks

Richard Kwon: Sony is finally becoming a major player! With Sony bodies and current lenses plus Sigma Art lenses is going to make Sony a major player. I can't believe they put so much in the Sony a7 III... Something Canon should think hard about and learn about!!! Way to go Sony!

I actually suspect that Canon are going to impress this year with the 7D MkIII and the replacement for the 5Dsr...for DSLRs anyway. More of a worry for Nikon than Sony I suppose.

Even I’m a little tempted by this camera and I’m a Fuji fan.

Michael1000: I don't understand why it has a crop when shooting 4K/30p.

Rolling Shutter is always a big issue with APS-C and especially larger FF non-stacked sensors.

(unknown member): I just realized that not only the Viewfinder, but also the screen on the back has a reduced resolution compared to the A7R III. I don't even find the screen on the A7R III particulary great - the Nikon D850 has a much better one.

I’ve noticed that with my friend’s Nikon’s...they have really high image quality back panel LCD’s, much better than my Fuji or Canon.

tabloid: Not sure about this.....but isn't the Sony a99II a better all round camera than the a7II. Also I wonder if Sony are about to release a a99III. Now that should be interesting.

I suspect the a99II’s days are numbered. Sony seems to be shifting most of its r&d to the mirrorless E-mount. I don’t believe there is ever going to be an a99III.

This is Sony’s most compelling FF camera yet! Very well featured for the price and about as much as many enthusiasts would ever need. I suspect its going to be quite a hit for Sony.

I wonder why they reduced finder magnification? I really appreciate all the improvements this camera offers over the X-T2. But it’s too bulky and heavy for me. Hopefully the upcoming X-T3 will offer most of these, together with a brand new sensor and processor! But without the added bulk and weight, I can live without IBIS, which the X-T3 is rumored to not incorporate anyway.

Those camera improvments seem to be mostly gimmicky. I still think a variable aperture on a smartphone’s tiny sensor is pointless. Wide aperture shots on my smartphone still provide excellent DOF on landscapes while allowing for shake free fast shutter speeds. While if you want shallow DOF on a smartphone, there’s alway’s portrait mode.

Edmond Leung: So, we should more focus on chemical studies to support electronic development.
It seems the best investment in photography is still the good optical lenses, but not the digital cameras. Digital camera technologies are too easy and too fast be outdated.

badi couldn't’ agree more! I compared some of my photos from my EOS-20D (circa 2005) to my EOS-80D (recently purchased) and in most situations, especially on a quality high-res monitor (I haven’t printed out anything in years) there wasn’t much of a perceptible difference in quality.

Hello, layman here, what’s dark current?

Link | Posted on Feb 22, 2018 at 12:51 UTC

Wow! Seems like the holy grail of photo-sensor design has been achieved here. Just wonder how long it will take to become affordable, reliable and wide-spread? Maybe in time for the Fuji X-T3 later this year? LOL! Of course not. Still fascinating tech though.
