Can someone explain how fractions and decimals got mixed into the same “number” (eg. 1/2.3) ?Even when the reference of TV tubes was valid, this would be strange!

Recently, a discussion in the DPReview forums posed the question: "What have you learned that you would tell beginners?" We thought we'd share what your fellow readers had to say, along with some insight from our editors.

We regularly receive emails from readers confused as to the actual size of sensor used in digital cameras. Sensors (CCD / CMOS) are often refered to with an imperial fraction designation such as 1/1.8" or 2/3", this measurement actually originates back in the 1950's and the time of Vidicon tubes. Those who find the specification sheets for these sensors are then even more confused about the relationship between the fraction and the actual diagonal size of the sensor. Below you'll find an explanation and a table of common sensor sizes. We'll be adding this information to our glossary for future reference.

They may both be correct - each of theses sensor 'sizes' are actually sensor 'types': they are simple the nearest classification that a particular sensor falls into.

The 'Type' designation given to today's CCD sensors is that it harks back to a set of standard sizes given to TV camera tubes in the 50's. These sizes were typically 1/2", 2/3" etc. The size designation does not define the diagonal of the sensor area but rather the outer diameter of the long glass envelope of the tube. Engineers soon discovered that for various reasons the usable area of this imaging plane was approximately two thirds of the designated size.

A faster sensor, improved autofocus and video see Nikon's third-gen mid-range full-framer go toe-to-toe against Canon's EOS R6 II and the Sony a7 IV. We feel its all-round ability lifts it to the top of the pile.

When the manufacturers say they've created a camera for 'creators' or vloggers, that doesn't mean they've turned their back on photographers.

Above $2500 cameras tend to become increasingly specialized, making it difficult to select a 'best' option. We case our eye over the options costing more than $2500 but less than $4000, to find the best all-rounder.

Could you please tell me the dimensions of a 1/4'' sensor?? I have found two different versions: 3.2 x 2.4 and 3.6 x 2.7. Which one is the correct??Thank you.

What’s the best camera for around $1500? These midrange cameras should have capable autofocus systems, lots of direct controls and the latest sensors offering great image quality. We recommend our favorite options.

Adobe's continued working on its Content Credentials system. We sat down with the head of the initiative to discuss new developments and its future.

This designation has clearly stuck (although it should have been thrown out long ago). There appears to be no specific mathematical relationship between the diameter of the imaging circle and the sensor size, although it is always roughly two thirds. Each 'Type' represents a class of sensor around these dimensions, rather than specifying an exact size.

What’s the best camera for around $2000? This price point gives you access to some of the most all-round capable cameras available. Excellent image quality, powerful autofocus and great looking video are the least you can expect. We've picked the models that really stand out.
