Question: Can i set the aperture and the iso on this meter? It's important for shutting portraits.
Document: This is really nice as an inexpensive light meter. But it only works with setting the shutter. You can't set in the aperture and get a shutter speed. Since aperture is so important for portraiture, I've had to return this and get a model that lets me set aperture and get shutter.
This is my first light meter which I bought for the purpose of product or portrait shots using manual exposure. The little unit does a great job and is easy to get started with. Once you set the ISO and desired shutter speed (shutter priority), the exposure is measured with the push of a button. You can then cycle through the various shutter speed / aperture combination and choose the desired one (e.g., if aperture priority is desired).
Simple, simple, simple! Once I set the stops according to my camera it does what it should. I get perfect exposure or with in a stop of perfect every time. The best is once you record a reading it holds that reading of light. You can then open or close your aperture, shutter or change ISO depending on what you are capturing then transfer those readings to your camera and still maintain perfect exposure.
pretty good meter only thing that bugged me was that the ball head is pretty lose and slides away from the sensor . and it only has shutter priority mode not aperture
The Sekonic L-308s offers a good balance of features and price point. It handles reflected and incident metering, ambient and flash, and readings in EV or shutter/aperture. A good basic light meter for occasional use at a reasonable price.
This meter isn't as feature rich as some, but it has all the features I need in a small, lightweight package that is as easy to carry in a pocket as it is in a camera bag. It is very accurate, runs forever on 1 AA battery. Lack of Aperture priority would probably be it's biggest weakness, but was certainly not a deal breaker for me.
Tested this side by side with a $700 Sekonic light meter and got exact same readings just about every time, down to the decimal. Small enough to fit in my pocket which is ideal on set.
I have used this light meter on several sets now and it hasn't failed me. It's small, convenient, and I wear it on my hip at all times on set. It gives precise readings and is completely straight forward and intuitive... and you can't beat the price!
The unit can be set for incident or reflective lighting and also allows for exposure value (EV) readings as well as sync cord and cordless flash mode.I would definitely recommend this unit if you are thinking about purchasing a light meter.
This is good for person who uses SLR camera. DSLR has better light meter built in. This is for those people who uses the completely manual Hasselblad and large format camera who needs to quickly get the correct aperture setting and shutter speed. I used it for adjusting an old Hasselblad medium format camera and a 35mm SLR, made by Canon. This is good for portability and accuracy. It saves the costly film from being wasted with wrong exposure.
Answer: No, the meter lets you set the ISO and the shutter speed and it displays the aperture. Once you get a reading, you can get the other equivalent aperture/shutter settings by using the buttons on the side. If you're using flash and trying for a specific aperture, you'll have to vary the ISO value.
