What To Know Before Buying A Camera

1. Storage Area

When the brand-new cam body you are thinking about has a higher megapixel count, difficult drive area is the apparent impact. More pixels suggest larger picture files. In my example, the Sony a7R produces 36MB RAW files. The a7R II pumps out 42MB RAW files– that has to do with a 16% boost. Non-trivial for disk storage, but workable. If I mess around with uncompressed RAW files, I’m looking at more like 80MB per shutter press. I’ll hazard a guess the a7R III will produce even bigger RAW files, on the order of 50MB to 70MB.

What about sd card? How large are the ones you own? If you are still shooting with 32GB memory cards, that might be a problem. Using my example once again, my a7R might take around 900 photos before filling a 32GB card. That drops to more like 750 with the a7R II. Or a mere 400 for those 80MB uncompressed RAW monsters.

Storage is reasonably inexpensive, but for respected professional photographers (believe sports, wildlife, weddings), you might be consuming disk space and memory cards much faster than Pac-Man consumes dots. Forecasting your storage requires is easy sufficient math. Just know those storage needs featured a cost beyond the cam body– and they are recurring costs.
2. Lens Compatibility

Many of us that have actually been into photography for a very long time have an investment in lenses. Perhaps you’ve scrimped and saved to get some actually excellent glass. You require to consider lens compatibility if you are thinking about a video camera body from another vendor. A prime example is moving from a DSLR system to a mirrorless system.

All things being equivalent, it’s probably more suitable to protect the investment you’ve made in lenses. There are lens install adapters out there. Read the spec sheets. Adapters have actually improved and better. You have to do your research. Does the adapter support your lenses? What functions (e.g. auto-focus) will or won’t work? What features (e.g. focus speed) are obstructed by the adapter?
3. Lens Resolution

You are drooling over that new, high megapixel cam. And maybe you are able to keep using your existing glass with an adapter. Nevertheless … can your existing lenses fix enough information for that huge new sensing unit? A top-notch sensor coupled with a lens of lower optical quality will not produce ideal images. Excellent glass from a few years back might or might not depend on the job of fixing 40 or 50 megapixels of data.

DxOMark added the “affective megapixel” to their lens scores a number of years ago. A good feature of the DxOMark website is you can check the scores of a lens as installed on a range of electronic camera bodies (presuming the combination has been checked). I examined my Sony lenses on DxOMark and the perceptual megapixel (sharpness) worths increased going from the a7R to the a7R II. Sony constructed the lenses planning ahead to larger sensing units. Did they believe all the way ahead to a reported 50-60MP a7R III sensor? We will see.

I likewise temper by-the-numbers rankings by asking other professional photographers I rely on and know that use the gear I’m thinking about. Naturally, I can just ask about electronic cameras that exist. I have lots of photo buddies that utilize the a7R II. If I jump on the a7R III train early, I won’t have much tribal understanding to use.
4. Computing Horse power

When moving to a brand-new electronic camera body, the power of your computer system is something all to frequently ignored by photographers. Envision going from a 20-megapixel to a 40-megapixel electronic camera. You have actually doubled the size of every picture you are processing. Can your computer handle that?

In this example, you are asking your machine to do double the work. Of course, you do not want to have a sluggish processing experience. If your system is a couple of years old, you will most likely experience sluggish behavior. In my viewpoint, the days are gone in the photography world where we can anticipate to utilize the same computer for more than a few years without an upgrade (or tolerating a slower experience).

I attempt my finest to get 4 years out of a desktop machine … which’s pressing it. When I acquire a system, I get the optimum config, especially for parts I understand I can’t quickly swap in and out to upgrade myself. I also add loads of memory and future-proof my system as much as possible. I’m not anticipating my next iMac update– memory will not be user changeable. Apple’s prices on RAM is … well, let’s simply state off market costs.

If you’re able, get a couple of test files from the body you are considering. You might have the ability to discover some online. Or find a professional photographer pal that is utilizing the video camera you are considering and try working with the files on your machine. Visit a local video camera shop and ask to take a few snaps to your own sd card. Or rent the body for a weekend and give your processing and cataloging workflow a real-world test. Another idea is to sew together a few panoramas and take those through your workflow. They are morally equivalent to large RAW files with lots of pixels to push.

And prepare yourself: you might either need a computer system upgrade as well or cope with a sluggish experience for a while.
5. What Issue Are You Attempting to Fix?

The last consideration on the list need to be the first thing you consider. Why are you getting a brand-new camera body? I ask myself what photographic problem the new equipment will fix when I think about a brand-new gear purchase.

Often the reasons are easy to rattle off. Your present video camera 10 years old and reaching the end of its life. Or your present camera is flat out broken! Other times, the benefits are nebulous, the perceived issues are more subtle. You ask yourself “Do I really need that gear? Or do I simply desire it because it’s brand-new?”

Difficult drive space is the apparent effect when the new electronic camera body you are considering has a higher megapixel count. If you are thinking about a camera body from another vendor, you need to consider lens compatibility. A good function of the DxOMark website is you can examine the ratings of a lens as mounted on a range of camera bodies (assuming the mix has actually been evaluated). The power of your computer is something all to typically overlooked by photographers when moving to a new camera body. Why are you getting a brand-new cam body?
