ChaoPhraya Sketchwalk in Bangkok (Video)

Here's the video I made from my recent sketching trip in Bangkok.

I brought the new GH3 along together with the Panasonic 12-35mm f/2.8 and Olympus 17mm f/1.8 lens.

The 12-35mm lens is a fantastic lens for traveling. It's not light, but it has a very useful zoom from the wide of 24mm to 70mm. The main advantage is you don't have to change lens, basically same as kit lens, but with the f/2.8 you get more leeway when working indoors during the day.

For low light, I brought the Olympus 17mm f/1.8 lens. I was deciding between the Voigtlander 17.5mm f/0.95 and the Olympus. In the end, I favored the lighter setup for the trip.

The f/1.8 lens works well at night, but it has it limitations. f/1.8 is relatively fast, but when compared to the f/0.95, it's still almost 2 stops slower.

The f/1.8 lens is good for night photography when there are lights around — the street lamps, indoors at night.

When it comes extreme low light situations, such as candlelight, a nighttime BBQ, you need the fastest lens possible. When you cannot predict the lighting, you need the fastest lens possible.

This was the sort of lighting I was shooting with. For photos, it's still acceptable to shoot at f/1.8 ISO 3200, and maybe ISO6400. Photos will be noisy but alright for viewing online.

The videos I shot at high ISOs of 3200 and 6400 are just too noisy to be used. They are basically a sea of moving grain.

For my next trip, I'll definitely be bringing the f/0.95 lens. It's effectively a 2 stop advantage. The video can be then shot at ISO 800 or 1600. That would have made a difference between having footage you can use or not.

So while the Olympus f/1.8 is fast, sometimes it's just not fast enough.
