Many of you contacted me after I wrote my post about the Olympus EP3 and my excitement over their addition of two stellar prime lenses, the 12 and the 45 respectively. The questions often revolved around why I wasn’t more excited about zoom lenses. For those who are new, a prime lens is merely a […]

UPDATE: Yes – sometimes I am a bit stupid. Turns out the lens isn’t blue – well it is blue but you can remove the blue cover and then it’s not blue – so ignore anything I said about blue lenses and Olympus, don’t fire that guy after all :) It’s long been THE problem […]

I was privileged to sit on a panel of advisors for one of the lens manufacturers last year. I was allowed to give my input to a design team that was working out the lens of the future. I doubt I’ll live long enough to see most of these recommendations come to life, but I […]

I had some fun shooting at the classic car show in Gig Harbor this weekend. I’ll have another post on how to shoot car shows, but for now, suffice it to say that with some “challenging” backgrounds, focusing on details is usually the safe bet. I really liked the hood ornament on this old Buick […]

You’ve seen the claims: “This is the sharpest lens I have ever used.” But how does a person know whether or not a lens is truly sharp? And is sharpness the only criteria by which we should decide to use a lens? I have used nearly dozens and dozens of different lenses in my career. […]

I was looking for a mid-range telephoto zoom to use as a flight lens or a medium landscape lens.

Nikon* offers the 80-400 VR, but that lens doesn’t focus quickly enough for me. They also offer the 300 F/2.8 – but it’s too heavy for handholding.

This led me to research other options. Several people suggested the Sigma 100-300. Since I enjoy the Sigma 300-800 f/5.6 so much, I figured it was worth a shot.

The first thing that attracted me to this lens was its internal focusing. That means the lens doesn’t get longer as it extends to 300 mm. I also liked the fact that it had a relatively fast (f/4) constant aperture throughout the zoom range. Lenses with variable apertures tend to be less sharp and contrasty than lenses which have a fixed aperture. Continue reading
