Confusion at the Border: Photography Versus Astronomy
One of the biggest confusions that you might notice as you venture into astrophotography is that photographers and astronomers measure their equipment differently. Photographers tend to refer to their lenses in terms of their focal length, while astronomers refer to their telescopes by the diameter of their opening. Thus, a 75mm f/6 telescope has a focal length of 450mm. Meanwhile, a 75mm camera lens at f/6 has an aperture of 12.5mm. If a photographer is told that someone is shooting a 155mm lens hand-held, it would not raise an eyebrow, but an astronomer told the same thing would be incredulous! I can only barely lift my 155mm telescope onto its mount!

A Review of the Versatile Canon RF 14-35mm f/4L IS USM Lens
A wide angle zoom lens is one of the most versatile out there, useful for a wide variety of scenarios in both photo and video work. For those who do not need the extra-wide aperture of an f/2.8 lens, an f/4 version can save a lot of bulk and money. Canon’s RF 14-35mm f/4L IS USM lens features a wider focal length than most such zooms and adds image stabilization, and this great video review takes a look at the performance and image quality you can expect from it in practice.
Is This Affordable Bokeh Master Lens Worth the Price?
50mm lenses are some of the most popular out there, and they range from sub-$100 f/1.8 versions to well over $2,000 for professional-level f/1.2 versions. However, Meike makes a 50mm f/1.2 lens for all popular full frame mirrorless mounts that costs less that $400, making it a potentially appealing option for photographers and filmmakers who love bokeh but not the money it often costs. This excellent video review takes a look at the lens and the image quality and performance you can expect from it in practice.
