I'd love to know how well this works. Been thnking about something
similar myself for the 350.

Please be sure that the 50-250 results are no better than the 85-250. I
don't wanna have to lust after **another** lens! :>)
BTW, has anyone offered to loan a 35-80/2.8?

I got my issue yesterday. The article is by Keppler. It tests mainly
Nikon F5 with and w/o MLU. Results are astoundingly better **with** MLU.
Sometimes exceeding **two** or even **three** times the resolution of no
MLU! The OM-1 vs OM-4T results are not quite as eye-opening, but the -1
with MLU does show up to 43% better resolution. The 'worst' shutter
speeds for the 4T are 1/8 and 1/15. (BTW, it's interesting to see his
comparison pix of a sliver of -1 and a -4T, showing where the MLU lever
used to be is now the viewfinder illuminator. It's interesting because
the -1 he shows has **red** leatherette on the body.)
**Now**, conspiracy theorists, listen up! At one point he lists **all**
the current SLRs which have MLU. I won't list 'em here, but suffice to
say most every mfg'er has at least one. Except Olympus. Now, here's the
strange part: Next paragraph reads: "The Maxxum 9 and Pentax PZ-1p MLU
systems are different from the others. Instead of locking up the mirror
manually,..., the **self-timer** is used to lock up the mirror about 2
seconds before the exposure. ... I like (this system)...."
Now, my conspiracy question should be obvious: Why are the 4Ti and 3Ti
not included in his list? Their self-timers do the same thing, albeit
12 seconds before exposure. Why did he single out Oly for criticism in
the article. (The point of comparing the -1 to the -4T was to see if
Oly's engineers had been truthful when they told him the mirror damping
on the 2-4 was so good that they didn't need MLU.)
Anybody know Keppler's e-mail address?
