I want the non IS version. it si lighter and sharper and I have no
need for IS.
Are you really sure you have no need for IS ? Also do you have any
real proof that the non IS version is that much sharper ? I have
often heard tons of people say this and the basis of it seems to
result from an unreliable photodo review of the two lens where the
IS version is rated very low for some reason, way lower than it
should be for a lens of its class.
Ive seen no hard proof from anywhere shoing the non IS version
looking any sharper, the view reviews i have seen always show them
to be the same for all intensive purposes
You hear the same with the 70-200 2.8 IS and non IS. some people
claim the non IS is sharper and then other people such as Stefan
will tell you their IS verison is shaprer than any of their copies
of the non IS verision.
Now thats talking about the overall tripod mounted absolute
sharpness of the two. Lets talk about relative sharpness. As
you know, I had a 400 5.6 prime a while back, the sharpest L prime
around in the non supertele class.
If i put it on my tripod and used MLU it was in fact sharper than
my lowly 100-400L. Not a big surprise there, prime beating a zoom
and all right ?
Well when I shot both handheld and tested them, the differences
were negated, and in fact with a 1.4x TC the 100-400l was always
sharper, the prime couldnt produce anything due to shake. This
was on an afternoon with decent light about 3pm
Now at midday when both len were getting 1/100th the story is a bit
more in favor of the prime. Depends on what time of day you
shoot. For me, and my skill level, a poorer quality 100-400L at
1/250th at 400mm with IS turned on is alot sharper of lens than a
400 prime at 1/250th at 400. as they say, your milage may vary
Now if you look through most of my shots, Im always at about
1/125th and usually iso 400 or 800. Thats just what a 5.6 lens
seems to get with non direct sunlight. I cant shoot at 1/125th
handheld. Some people can but not me.
Thats one of the reasons I returned my 50-500ex. Took a few trips
to the zoo with it and couldnt get sharp shots due to shake. The
bright sunlite shots were great of course as its a great lens. But
my subject matter is usually in non direct light or shade. Became
a very poor lens for that.
Now I think before you make any judgements on if you need IS or
not, wait til you try out the lens. Go into it with an open mind
regarding IS. Lets face it, some people that done have IS versions
of a lens simply tell themselves they dont need over and over.
Now for some of those people its fully true, for others its wishful
thinking and they are just trying to fool themselves.
If your going to use the lens just in good lighting, tripod mounted
or for birds in flight and other action, then NO I dont think you
need IS at all, it would be of no use for you.
Im under the impression that you, like myself, do enjoy shooting at
zoo's sometimes. That typically means not much good lighting, and
trioods are a pain. Give your new lens a trail under such
situations and see if f4 is giving you enough shutter speed.
It very well could be fast enough to give you sharp shots, people
have taken great photos without IS for years. But people have had
blurred shots due to shake for years as well.
So get the lens and try it as much as you can. If your getting
some shots with shake, then maybe its not right for you. You paid
what, like $740 i think you said and with no tripod collar ?
Fair price if the lens works for you, but dont forget you can find
the IS version for not much more. The copy I had a few weeks ago
I bought for $850 with a collar, UV filter and it was rated at the
local shop as 9++, basicaly new in the box. If i had known you
were looking I would of let you know it was availbile when I
returned it. but thats an average used price for them
So just try it out and then form an opinon. A good friend of mine
who's shooting alot of wildlife out west once told me he had "no
need for a lens longer than 200mm" and now he owns a 600 f4, the
non IS version but it just goes to show how what we think we need
at one time can vastly change.
