X2D Firmware 4.0 Multi shot 4x added

There is no sensor based stabilization in the CFV 100c (I believe) so I'm guessing no multishot as it would use the stabilization mechanism to do this.

I am not the photographer of the flowers but I have seen similar artifacts. I believe they are possible due to movement of the subject as that is where I have seen them in my testing. Even though the flowers seem to be silk or artificial they still may have moved during the shoot.
Also I agree you can possibly sharpen up a non multishot to get the similar degree of details. However where I am seeing the benefit is in shadow details and recovery. The difference between MS and non MA is impressive both in extra details and lack of noise. Also with higher ISO images less noise.
As Phocus software makes this process so easy if tethering is possible to me it makes sense to shoot a MS and then a single of the same subject.

Previous iterations of the Hasselblad digital backs (pre-CFV) had a Piezo-driven motor that moved the sensor for the multi shot sequence. As a result, the chassis of the digital back was larger in order to accommodate this. There was a physical difference between a single shot and a multi shot capable digital back. I am doubtful we'll see this happen in the CFV series.

Artifacts in multishot backs are sometimes due to the internal shifting mechanism not working 100% corrector, or due to the slight change of lighting, so you can shoot a perfectly stationery object and still get it from time to time.

Yeah, I would imagine the voice coil based image stabilizers are less accurate for shifting the the peizo actuators in Sinar and Hasselblad multi shot backs too. Maybe that’s untrue?

Another one is the entire house/apartment/building vibrating… Someone using their washing machine near our unit is enough to vibrate everything enough to ruin multishot.

with Sinar multishot I was surprised how well it was implemented in their last prudced back,the 'Exact' model - it works perfectly fine in at least 90% shots, regardless of circumstances, while with 54h it was a hit and miss at around 50% and could be ruined by the slightest vibration, for example by a truck passing by your building. That was a nice surprice, considering that the precision of shifting had to be increaed at least twice.
I am not sure how good the IBIS mechanism is in respect of getting back to the exact same position - if it is anywhere near the Exact's performance, then it is a great feature to have, especially in higher shots mode than just 4 (sinar does 16 shots - real colour and 4x resolution but Hassie only 6 max, so probably they will aim with real colour and interpolated resolution or 4x resolution and interpolated colour.)

Since we are talking about static scenes here, I wonder how good would be in comparison if one uses an achromatic digital back to make 3 shots with the three base color filters mounted on the lens, and then compose the three images into a color one.

The hvac system turning on ...

I also don't know how consistent the results are with IBIS-based multi shot and how they compare with piezo driven motors from legacy digital backs. The comparison is a moot point for the most part, since the last piezo-based multi shot digital backs were the Sinar eXact launched in 2012, and the Hasselblad H6D-400 launched in 2018 (now discontinued). The essential data is simply how reliably does the IBIS driven multi shot perform.

My first quickie test looked excellent. More testing is needed.

If it can't be used for Soup, then what's the point? :LOL:


Motion artifacts. Very sad.


It works REALLY well on stationary objects. I just have to find some.

Fine Art! Take some of these images, run some color alterations over them, and you can have your own series of Warhol-inspired Soup images!

LOL, it takes a multi-shot back to show signs of life in the sleeping/sprawling Soup!

Hi,
Probably good, for the 4 shoot, it won't help with the 5 shoot (increased resolution) and it's a lot more work, to get the same result for a lot more money,
I will call it pretty bad deal 🤣 and nonsensical business ;)
Clearly if one already have the think, it's a nice alternative.

best regards.

Well, it depends on how stable and precise an IBIS mechanism can be. I often see artifacs produced by multishot implementations.
As for the speed, no one here in the MF forum expects to be a fast shooter. 😉

Anyway, my idea was mostly in the spirit of making an experiment and a comparison of results. I by no means meant to suggest it as a practical or economical alternative. 🙂
