Post Title: This is like my third attempt why wont it work

Guess who isn't dead.

Despite what I'm sure many of you believe, I am still very much alive. An extra difficult semester and a conference in Mississippi, combined with a total computer failure have set me very far behind. ALAS! We will continue forth, marching onward into the night. RAGE! Rage against the dying of the light. Or something like that anyway.

For real though, things got crazy but I'll hopefully be on the ball from here on out. Thank you everyone for sticking around! Now that my ridiculous intro is over I'd like to have a little talk about how size under the hood, makes your image look good.

Sensor sizes: Size very much does matter.

Below there is a chart, that shows most common (and many uncommon) sensor sizes. The varying size has many effects that can entirely change the properties of your image. Focal length, depth of field, light sensitivity, and resolution are all effected by a sensors size. 

Imagine you have a full frame, 50mm lens. This lens is designed to only focus an image to the distance and size of a full frame sensor. If you were to adapt this lens to say, a Micro Fourth Thirds (or M43), you would receive a tight crop on the available image. Because the lens focuses the image to an area larger than the available sensor, part of the image is lost. This is how Metabones Speedboosters work. The speed booster is designed to focus the image onto a smaller image plane, allowing for a crop reduction and a boost in available light (since the light is focused more, it usually raises the image an entire stop, that's double the light baby!).

"Rylee!" I hear you cry, "How else does sensor size effect available light??" Well, let me explain. On a smaller sensor, there is less room for photo-receptors. Therefore, it is difficult to include high sensitivity ISO on a smaller sensor, resulting in a generally noisy and unusable image. Take for example, the GH5, in comparison to say a Sony a7s 2. Because the A7s has a larger sensor (almost double the size) of the GH5, it is able to interpret low light images much better, and has a much higher effective ISO. So while it may not directly effect the actual ISO, the effective use of a high ISO is considerably lower on a smaller sensor. 

All of the research for this has kinda made me want a GH5, so I may write a blog post defending DSLR filmmaking after all, despite my best efforts I made clear in an early blog post. Thank you all for reading! If anyone has any questions feel free to leave a comment! I'd love to help out in any way possible, and who knows, I'll probably learn a lot along the way too. Hopefully blogs will be more regular from here on out, so get ready for more camera related geek sessions like this one.
