The D3S is better at high ISO, but it's not night and day.

2010

Everyone knows the first Mirrorless digital camera with a 24x36 sensor (FF)

Less sure on the other hand for the first APS-C ML

It's the Samsung NX10 (2010)

14.6 MP sensor (4592x3120)
1st APS-C mirrorless
$750.00 CAD

Samsung has come and gone very quickly from the digital camera market.
Surely to focus entirely on smartphones, a much more lucrative market!

In 2010, after several years of waiting, Pentax's digital medium format is finally available.
The Pentax 645D is equipped with the magnificent 40 MP Kodak CCD sensor.
The great strength of the 645D is to be very versatile and easy to handle, it can be used both outdoors and indoors.
And what about the pleasure of looking in such a beautiful viewfinder!

Pentax K-5 (2010)

The same year Pentax released its very famous Pentax K-5, a Great little DSLR :)

Pentax Q (2011)

Decidedly, Pentax was in great shape in the years 2010-2012!!

Here is the opposite of the MF Pentax 645D
The mini, mini, Pentax Q (2011)
1/2.3" (6.17 x 4.55 mm) 12 MP (4000x3000) sensor
Price: $800.00 USD
With a multiplication factor of 5.53
ISO 125-3200

It took me 10 years to get one.
With the K5 I brought a used mk2 well before getting the Q.
The 645D is going to have to wait quite a bit longer, none of my lenses adapt easily to it, so the initial cost of ownership will be significantly higher. My 5x4 lenses could be adapted but I doubt that would prove practical in use.

How many warehouse do you have for all your cameras Marc ?

Unlike others, FA 645 lenses are easily found at very affordable prices.

But for now, I'm very happy with only two lenses
Pentax-D FA 645 55mm f/2.8
Pentax FA 645 120mm f/4 Macro

*Actually, I'm running out of space. 🤣

A very nice lens.

Careful your in danger of sparking off a fresh attack of GAS

The Pentax 645D is the only digital MF I can afford. 😁
The other MF are unaffordable 😩
But I would also like to have one of the Hasselblad digital H System. ❤️
It's important to keep dreaming 😇

Hi,

The highest price I paid for any of my P645 lenses was $200. Most from Robert's Camera in Indianapolis back in 2000.

I bought lenses with greater performance for less money than I would had paid for old Pre AI Nikon lenses.

Dirt cheap, I'd say. Which is ironic since they are mostly made from sand. :P

Just for fun, I made a comparison between the two Pentax 😈

Prolific year for Panasonic, which allows the Lumix GF2 and GF3 to be released in the same year!

It is the proliferation of µ4/3 It's a good time, the period just before the invasion of smartphones.
