I’ll save you having to read a confusing lesson by myself on the technicalities of full frame cameras.
If you’re interested, I have linked a simple 10 minute video below on the basics of Full Frame vs Crop Sensor or “Entry Level” Cameras.
Josh Katz explains it very well. See full frame vs crop sensor/ aps-c video here.
Full frame? Whats full frame? Do i need it for travel?
To avoid camera babble deterring from my list of my photography gear, I have written a post here about Full Frame Mirrorless Cameras For Travel and why it is my choice.
so do you need it? wellLL, its full frame for me all the way - here’s why.
YOU CAPTURE MORE OF THE SCENE INTO YOUR PHOTOGRAPH WITH THE SAME LENS ON A CROP SENSOR
The main appeal is it enables you to capture more scene standing from the exact same position using the same lens as you would with APS-C, Full Frame captures more image because well, it’s sensor is bigger so it sees more.
Also, the more image you fit in, the more you can crop it later on to use a portion of the photo. Instead of the inverse and not actually having the photo there.
Full Frame = More Image!
WAY BETTER IN LOW LIGHT WHICH IS GREAT FOR LESS NOISE
Travel can be so unpredictable with its lighting eg. Inside one moment, outside the next, night time attractions etc.
It is always good to be able to shoot in low light with a higher ISO without compromise of quality. No one likes a noisy photograph.
BETTER CONTROL OVER DEPTH OF FIELD
You can pull backgrounds and foregrounds more out of focus as the larger the sensor a digital camera uses, the shallower depth of field you get, this is why portrait photographers rave about full frame. So if portrait work is something you want to focus in your travels well..
BUT, if you want to shoot landscapes and need to make your depth of field large and sharp in the distance. you'll be able to get away with using, say, f/11 on a crop sensor, whereas full-frame camera you may have to use f/18 to ensure your scene is sharp from foreground to background
THEY’RE ACTUALLY PRETTY AFFORDABLE THESE DAYS, SO WHY NOT?
As I wrote above, you can pick up a Sony A7 with a Full Frame sensor for around $1000 USD with a Kit lens included. Yes, it is an older model but still packs a punch and you’re getting all the benefits a FF can give you.
5 years ago I wouldn’t have been easily suggesting that you go out and buy a full frame camera, because well… they cost about double and I really started to get tired of the weight and size when travelling.
