Keeping it for Indoor Events

As I've mentioned, I'm migrating back to Canon lenses from my experiment with Sigma lenses designed for my smaller crop sensor bodies. I've sold three of the Sigma lenses so far and the one which hasn't had much interest - probably due to cost - is the 50-150mm f/2.8 APO EX DC OS HSM lens.

This lens has a field of view equivalent to an 80-240mm lens on a full frame body. Traditional options in this range are 70-200mm lenses which have a field of view equivalent to a 112-480mm lens. This Sigma is a very nice lens but I found it a bit lacking for field sports back in the Fall. Where it excels, however, is indoor events where the range between 50mm and 70mm (80-112mm equivalent) can be quite useful and where the extreme long end of the 70-200mm is usually not needed. The optical stabilization also helps with slower shutter speeds which are sometimes necessary with indoor events.

So, I decided to use the Sigma for a flute choir concert yesterday. My kit was the Sigma lens, a Canon 7D body and a Canon EF-S 24mm f/2.8 pancake lens. Here are a few that show the range of the Sigma lens. For all the photos you may visit

50mm, f/2.8, 1/60 sec., ISO 1600

76mm, f/2.8, 1/60 sec., ISO 1600

118mm, f/2.8, 1/90 sec., ISO 1600

150mm, f/2.8, 1/90 sec., ISO 1600

So, since this lens has been discontinued by Sigma I think I'll hang on to it for events like this. For outdoor sports, a non-IS Canon 70-200mm f/2.8L will do fine.

Easter in Church with the Canon EF-S 10-22mm f/3.5-4.5 USM

I'm not a gigantic fan of variable aperture lenses but there's no reasonable Canon option for ultra wide coverage on an APS-C sensor body. Sigma has a constant f/3.5 lens with 10-20mm coverage but I've discovered that I feel more "at home" using Canon's DPP processing software and that will only correct aberrations for Canon lenses.

Accordingly, I've been reversing my migration from Canon to Sigma lenses although I'm still focusing mainly on lenses designed for the smaller sensors, the EF 70-200mm f/2.8 non IS for sports notwithstanding. In any case, I brought along the Canon EF-S 10-22mm f/3.5-4.5 USM to Easter services this morning.

My intention was to shoot wide open at various focal lengths at ISO 1600 in order to keep shutter speeds up for the hand held shots. Since I have 10mm images shot at f/4 I obviously didn't achieve that intention. But luckily it was a sunny morning and there was enough light coming in through stained glass windows for decent settings.

It's obvious which of these shots is a five file HDR composite. The exposure information is for the normally exposed image.

10mm, f/4, 1/60 sec., ISO 1600

12mm, f/4, 1/45 sec., ISO 1600

10mm, f/4, 1/60 sec., ISO 1600

22mm, f/4.5, 1/45 sec., ISO 1600

60mm Macro Lens on Peebles Island

Here are some shots from this afternoon's muddy stroll on Peebles Island with a Canon EOS 70D and the EF-S 60mm f/2.8 Macro USM lens. I was primarily looking for some leftover snow juxtaposed with some of the green which is just beginning to show itself.

Here are a couple of scenes that I managed to find.

But Macro lenses also focus to infinity and are good landscape and portrait lenses as they are generally quite sharp. Especially compared to zoom lenses.

The following photo is of the patch of ice you see in the middle right of the above shot. The pieces of ice were moving slowly and in the time it took to record the five bracketed shots which make up the final image they certainly did change positions. The HDR software, though, manages to adjust for this.
