As a working professional I usually keep my eyes open for the latest equipment released by camera and video manufacturers. I've always had this nagging doubt about the relevance of my equipment; the problem with technology, as we all know, is that it's out of date as soon as you buy it, particularly computers.

Cameras and video cameras are always evolving and it's hard to keep up with all the improvements with each new model, in reality do they really make a difference to the work you do and do you need to upgrade to the next model?

High quality camera equipment is generally built to last, so any new camera should last you several years unless you're a professional shooting a lot of images and the shutter counts exceeds it's limit. In this case you may part exchange your cameras for the latest model every 1-3 years as I do.

Camera manufacturers are always proud to announce their new models and what they're capable of; better quality, faster speed, outstanding performance in low light, super high ISO, sharpness etc etc etc; 

One thing they don't tell you, or if they do it's kept very quiet, is that with each new camera or video camera model the more demanding it will be on your PC/Mac. Higher file sizes with new camera models often mean your computer hard drive being used up more quickly, slower performance and in some cases your computer may not even be able to open the files.

It soon dawns on you that you need to invest in a brand new upgraded computer and suddenly that incredible price and cash back deal you recently bought the camera for has ended up costing you a heck of a lot more; and I mean a lot more.

I recently experienced this after purchasing a new Panasonic GH5 mirrorless camera www.panasonic.com/uk  which I bought from www.wexphotovideo to shoot video rather than take photos. Now the PC's and Mac my business has (4 PC's and a Mac) are all fairly high spec; unfortunately though the video files from this new camera lag (jitter) occasionally when playing the clips back. It's only when we use the editing program (Premiere) the clips can be watched properly and even then we have problems.

So even though we can play the recorded clips back, the opening and rendering of the clips is incredibly slow. On top of that the time it takes to download the images from your memory card also takes considerably longer.

So the situation with this new Panasonic camera has resulted in having a new PC built costing me £2500.00; it's the equivalent spec of a £4500.00 Mac (I prefer PC to Mac) so it really is a power PC...but it's cost me £2500.00.

Not only did I have to invest in this new PC but also when shooting jobs, particularly a wedding www.axweddingvideos.co.uk even a 64gb card fills up incredibly quickly. So over £200.00 was spent buying 4 128gn SD cards and I could do with at least another six!

Then there's the additional portable drives I've purchased to back up the larger size files. To date including the camera, new PC, memory cards and extras I've spend in excess of ££4500.00!!! But I did get £150.00 cashback from Panasonic!

So I got a good deal right??

When video editing we also use the Canon C100 www.canon.co.uk/  and last year started shooting in C-Log mode (lets call it the RAW version); the result? The PC slows down, memory cards fill up much quicker etc etc etc.

So my advice is that if you're about to buy a new stills camera or video camera have a look at your computer first and see if it can handle the new camera. The first thing is to  clear your computer as much as possible of all the junk that's on it, unused files, programs, hidden files etc etc. If you don't know how to do this speak to a computer specialist; it may be a simple case of of just clearing and reinstalling programs and you're good to go.

Unfortunately though that lovely new camera may end up costing you a heck of a lot more than you thought.
