Simply based upon images I see from others with exif intact and what I see people I know do.Yes, I think there's quite a bit we agree on.I think we agree on most things
Hard for either of us to really know anything about that. And all I really care about is what can be done rather than what most people do.except for two points.
1. Most users (not you by your post) will use any zoom they get primarily at one end of it's range or the other for the majority of what they shoot. They learn to see in two focal lengths mainly because they are alway limited by those two extremes of range.
I can agree with that.My point was not to suggest that MTF numbers provide all the information we need about a lens. I chose it merely to exemplify the more general point that a good standard zoom can perform about as well as a good prime, and at any rate sufficiently well, when shooting at the rather small apertures that the zoom allows us to use.2. I like photozone for what it offers but find comparing charts and percentages to be very misleading at times. From this part...

"On the other hand, sites exist that overwhelm you with MTF plots purportedly providing indisputable facts. MTF methodology has a genuine scientific foundation and there is nothing "wrong" with MTF as such. I even understand the mathematical equations. However, such statistics basically are as helpful as knowing the mass of a lens - on its own, MFT testing cannot predict the pictorial outcome of any lens. Thus, MTF tests will not show all problems from field curvature, colour fringing, flare and ghosting, the variability in performance that arises from near or distant focus, the subjective 'feel' of the images and in particular the out-of-focus rendition (given the buzz word of 'bokeh'), the way a lens handles under actual use, and so on. MTF data can just indicate there is a problem with a lens, or that a particular lens might be an excellent piece of glass. All of this information can be obtained as easy (but likely not as fast) just by shooting pictures with the lens. Averaging MTF numbers to arrive at a single value in order to rank lens quality is simply impossible and largely a waste of time."
That last sentence sums up how I feel about MTF numbers and using them to compare lenses. Especially based on opinions and the majority of reviews vs. what I see in real use.
