I’ve been pondering the intricacies of image resolution ever since I heard the Canon 90D was coming out with the new 32mp sensor. Many lenses they say do not have the resolving power to make use the the new high pixel density sensor. So the question is, do you forego the upgrade if you are using a 70D or 80D for fear that your version I L series lenses “aren’t going to work”, that the new sensor is going to “make your pictures blurry”?
Well the fact is that it is physically impossible to decrease your overall image quality by increasing the resolution of one or more of your components. Would your images be better if you bought all new series II lenses, of course… unless you have managed to snatch the latest lens technology off the assembly line, there is always going to be a better lens. Given enough money you will always be able to find a better lens than the one you have now.
So the question you have to ask yourself is an important and very basic question, am I still getting the shot? Are your customers still happy with your product? If the answer to that question is yes, I am still getting the shot. My customers are still happy with the product I am delivering, or I am not losing sales to my competitors with newer gear, then you probably should not upgrade yet. If you find that you will benefit significantly from more megapixels and newer camera technology then go ahead and take the plunge. If you can use greater cropping ability, better low light capability, better noise reduction and higher dynamic range, not to mention 4k video, then go ahead and buy the new camera and don’t worry about if there is another lens out there that can give you even more amazing results. You can cross that bridge when you come to it.
For me I am finding that my results with the 90D and series I lenses are good enough for now. My large metal prints look beautiful on the wall, my wildlife pictures are sharper than they were with the 70D with the same lens, and I am having more success with image acceptance at the stock agencies, in fact 100%. Due to new low light picture quality and higher dynamic range I am able to shoot earlier in the morning and later at night, while capturing more keepers. From just higher ISO and faster shutter speeds alone I am capturing more salable images. If I can capture an elk’s whiskers at 70 yards using the 1.4x extender and my 400mm series I lens, which by the way I can now use with auto focus, I’m thinking… it’s good enough! Would I still like to acquire a couple of newer technology lenses? Of course, I am always striving to improve the quality of my gear but for right now, good enough is good enough!
