Falcon II (Integrating detector)
Quantum K2 Summit (counting detector)
Both the Falcon II and the K2 will provide information at the Nyquist frequency of the image.
The most common magnifications used on both the Falcon II and K2 give approximately 1.4 or 1.1 Å/pix
Using a lower magnification may not give you more particles as you can not take as many movies per hole
Larger holes allow more images to be collected per hole e.g. for a 2 micron hole at 1.1 Å/pixel we can routinely get 65 movies/hour on the Quantum K2 and 75 movies/hour on the Falcon II compared to 0.6 micron holes where we can only get 30 movies/hour on the Quantum K2 and 45 movies per hour on the Falcon II.
