Latest Pentax medium-format camera utilizes 51.4MP CMOS sensor, delivers more depth

Ricoh has scheduled the launch of the Pentax 645Z DSLR, the higher-end, medium-format successor to the Pentax 645D camera that launched in 2010. While many might say the price of this camera is set rather high, the 645Z boasts a lot of significant features to warrant the price – and a relative “bargain” if your profession depends on this type of camera (e.g. photo studio photographers).  

The 645Z is fitted with a 51.4-megapixel CMOS sensor with an imaging area of 43.8mm x 32.8mm – an upgrade from the 645D’s CCD sensor. Because of this transition to a CMOS sensor, which is roughly 1.7 times the size of a full-frame 35mm, the camera is capable of supporting Live View as well as recording of 1080p video, something the older CCD sensor couldn’t do.

With a sleeker design that doesn’t include the modular back of its predecessor, the 3.4-pound 645Z has a weather-sealed body rated for use in extreme climate conditions, such as rainstorms and other unfavorable weather. 

With an 86k RGB metering sensor, the 645Z uses 25 different cross type points with two linear sensors at the edges of its active focus area to properly expose your subject in even the worst of low-light situations. The 645Z has a maximum shutter speed of 1/4000 and an ISO expandable to 204,800 to further ensure high-quality exposures that are crisp.

The Pentax 645Z is expected to cost around $8,500 (body only), but that price is more attractive when compared to some of the camera’s competitors, like Hasselblad and Phase One. You could spend upwards of $30,000 for a camera with slightly less powerful sensors and an inability to record HD video (although the competition is heading toward CMOS as well, the 645Z still costs less). The 645Z builds on the previous model by shooting up to 3 frames per second (enhanced from 1.1 fps) and an improved autofocusing system. These features enable the 645Z to perform at the level of its pricier competition.

So, what does this mean for us consumers? Most of us wouldn’t be using a 645Z to shoot everyday photos, but your next family portrait taken at a studio using this camera would have greater resolution – important for creating large portraits. Filmmakers would have greater depth control when shooting their movies, as another example.

The Pentax 645Z will be released by June 2014. The full camera specs can be viewed at the Ricoh website.

Best Camera Deals: Save on Canon, Panasonic, Nikon, and GoPro
fujifilm x t4 review set 2 dm 1

Whether you're looking for the best digital cameras or the best travel cameras, there are a ton of options out there, sometimes too many options, especially for those who aren't familiar with the photography world. Luckily, we've done a lot of legwork for you and collected a range of great camera deals across the spectrum, so even if you want something more sports-oriented, like a GoPro, there are a couple of deals for those too. So, let's jump right into it.
Today's Best Camera Deals
One of our favorite deals is the Canon EOS Rebel T7 going for $400, as it's one of the better DSLR cameras on the market, and it has a reasonably budget-friendly price on it, making it a great starter camera. Of course, if you've been in the game for a while and are looking for a powerful upgrade, the Sony Alpha 7R IV is one of the best full-frame cameras on the market, and while it still costs a hefty $3,200, that's still $300 off the usual $3,500 price tag. That said, if you're looking for something more portable and action-oriented, you can't go wrong with the GoPro HERO11 Black Mini, although if you're a professional content creator, the GoPro HERO9 Black 5K is probably the one to go for instead.

Do I Need a DSLR or a Mirrorless Camera?
Like most things, this really depends on what you're trying to do. Mirrorless cameras have fewer internal moving parts, which generally means they can capture images quicker, so if you're taking pictures of action-packed stuff like sports or animals in the wilderness, a mirrorless camera is a great option. On the other hand, DSLR cameras are great for low-light conditions and are great for anything from portraits to landscapes. DSLRs are also cheaper and have much better battery life, as well as having a decade or two worth of lenses to choose from.
