actually that's not true, the lens coatings are optimised for a specific wavelength and transmission coeficient of plane glass a function of wavelenth even before you add the coatings.

I would expect a variation in colour between different coating types (say SMC vs Tamron BBAR) and quite possibly between different generations from the same manufacturer.
I'm saying that there is a difference between lenses but that a lens would not change his colour, I could expect a lens act a bit differently in daylight then under tungsten but I don't expect it to be more green first and a second later be blueish under the same light source.
Or are you really saying that a lens can change his colour behaviour in a second?

Look at the path and the green around it, in the first it's more yellowish and in the second more blueish.

I went from DA40 + DFA100 to a DA*50-135 because of the versatility that wanted but I could afford the change without selling the primes so still use them all but for portrait the DA*50-135 is just perfect.

I also still want a nice series of Limited lenses, I still have my hopes up for something like a DA135 f/2.4 limited or f/2.8 if it's very small.

Maybe you just need a bigger bag Mike or take less with you

Never have a problem either, that's with the 18-55 that I've for almost 2 yeasrs now and the DA*50-135 that's almost a year old.

I think Hefty or John or someone else can tell you more about it.

Like said it's most likely just the name on the box, the catalogue number for example stayed the same so the lenses hasn't changed.

Peter, I believe both versions are the same so it shouldn't matter

The difference is most likely the catalogue name one with SMC and the other with smc.

For the weather you can try Wolfram, it doesn't show cloud height though but other interesting things.

Well John a dishwasher might be an option if you can lower the pressure of the water jets

Yeah but even when you pick up your camera it gets dirty... I haven't bought it to look at it
