Getting your money's worth...
I am writing this observation as kind of an statement of exasperation... (sigh).
One of the problems that I have been dealing with is the desire to see a better sensor and noise processing (smoothing algorithm) for the Full Frame camera. The α850 was a reduced speed α900, but identical in almost every other aspect. It was not an improvement. Again, since its release in 2008, the α900 has not had one, except for some firmware modifications.
In the meantime, we have seen Nikon walk all over with their higher-end sensor performance. Again, I have always wondered if SONY (Minolta) was going to stay in roughly the same body design, why not make the sensor interchangeable, like CPU chips in the PCs? That way, when the updated sensor became available... in it would go.
Anyway... I feel I have no choice but to keep plugging away with the older body... not that it cannot achieve a good image, but I know we can do better with a technology upgrade. Call it "Tweaknology"... allowing us to work "smarter," not harder. I do find it annoying to have to purchase a whole new camera body that looks almost identical to the former one.
Now, admittedly, there are those photographers that tend to "bounce" their equipment, unmercifully, and I have to shrug... as their gear will be short-lived. I am smugly reporting that I have portable computers that have survived since the early-80s. I was never one on those "kickstand-optional" kids, who just threw their bicycle down when they got off it. Imagine, actually parking it upright! This respect for my "toys" has carried on through the years and I still have nearly every camera I ever bought... and they STILL work! So, this modular upgrade seems more practical and "green," than to always be throwing away the last generation of equipment.
Don't get me wrong about this... I', not stuck on the idea of not developing... but, convenience has its price... and it looks pretty grim to me. A little more forward thinking and finance balancing would be deeply appreciated.
