Flash cards, Smlash cards, doesn't matter really. That's just data storage. If it works in her 5D, fine. Newer cards write faster is all. If she shoots bursts like at a sporting event or birds in flight, that's critical. If she shoots landscape or other types of shots that require some thought and setup between shots, not so important. I use but a few 512MB cards and a 40 gig Flashtrax storage device. Seems to get me there. When I fill a 512MB card, I download it to the Flashtrax while I shoot another.
As to her lens assortment, f2.8 or lower (faster) glass will produce the better image. Primes are primo, no pun intended. Good fast zooms are a second choice but she should avoid lenses in the f4-f5.6 range if she can afford better. Good DSLRs demand good, fast glass. That being said, I have several slower lenses that I like quite a lot. A Sigma 50-500 zoom f5.6 being one of them. I just can't use it in a dimly lit scene.
And you are both right. Many stock image agencies like Alamy and Corbis require images at around 60MB min. Hard to do that with a 6MP camera. What's harder is to supply them 'unsharpened' images which is what they ask for. Means Robyn will have to keep separate files for printing and submission to a stock agency. |
