Olympus 14-35, 35-100 zoom lens owners

The 2 lenses match very well and the 35-100 breathes even less than the 14-35. The min. focus is 4.6' which is not very close, but not a dealbreaker.
Weight and size are considerable but I would never use it off a tripod. Optical performance is phenomanal. If you already own the 14-35, you owe it to
yourself to get this lens.
 
Just received my 14-35 and 35-100. Haven't put the big one on yet, but the 14-35 does have the same iris change (in manual) that MonkeyKing reported and Editman confirmed. Basically there is a slight shift in iris (probably about 1/3 or 1/4 stop) as you zoom. At F2 there is no change, so it IS able to do F2 at the whole range. Other than that this lens seems great, and I don't see this issue as a reason to not get these lenses.
 
One remark. The AF100 sensor is smaller than the S35 cinema frame. The focal lengths have to be multiplied by 1.4 to get equivalents on S35. So 14-35 in fact offers the same angles as 20-50 on S35. 35-100 is 50-140. The most commonly used f-lengths in cinema in fact. Very handy.
 
I agree you could get away with the 14-35/35-100 duo. It covers most of the range one need. In fact these are the lenses I have stuffed in my bag along with the AF101. Rest of my lenses are in the 7D/5D bag.
 
Should both the auto iris and auto focus work with this lens? I have auto iris but not focus.
 
What adaptor do you guys use? I use the Olympus one (silver) and when I took the camera on it´s first day of a long shoot I noticed that it dosen´t fit very well.
It slips a bit back and forth when I pull focus or use the zoom. Is this normal or do I have a faulty unit you think?
 
My GH2 + Olympus 14-35 2.0, behaves differently.

Set to f2.0 zoom in tight to 35mm no problems, but when I zoom all the way wide to 14mm - somewhere about 15mm (guess) the f-stop changes, I hear the click, the footage goes darker, but the camera still reports f2.0.

Set to f2.2 there is no change throughout the entire zoom range.

So my results indicated to me that the lens was not able to achieve a constant f2.0, but could achieve constant f-stop at any other setting.

But now we are seeing different people having different results - this does not sit well with me... the image from this lens is fabulous, but these inconsistent results have me questioning the overall value of this highly priced lens.

I have the same one, and mine too dosen´t have a nice fit. It moves back and forth. Does the Pany behave the same way?
 
I started this thread originally testing the Olympus f/2 zooms on my AF100. Basically the iris glitch, as I call it, occured on all stops EXCEPT f/2 (wide open) accompanied by a very audible click sound. Now I have a GH2/GH1 and I share your observations; Even wide open at f/2 there is the dreaded iris glitch in both stills and movie modes. The glitch is more audible in movie mode but if you observe the exposure scale on the bottom right of the LCD you will notice a slight tic +/- in exposure as the image screen slightly brightens/darkens.
Very annoying especially in movie mode where it is noticable. Not so much in still mode but I have acquired several Leica R zooms w/o electronics so I can change focal lengths w/o that irs glitch. Olympus lens IQ is fabulous as you have noted.

Hey monkeyking, and editman...


I'm just trying to find out if we have the exact same thing - or are we getting different results?

I only get the one change (while at f2.0) right before full 14mm wide, the lens darkens.

Assuming the lens IS in fact at f2.0 throughout the rest of the range, this means that at 14mm it does not achieve f2.0.

While at any f-stop other than 2.0 there is no change or click throughout the zoom range.

Thanks so much for your time and input!
 
SP,
This thread dealt with the iris glitch on the AF100 with the f2 Olympus lenses. I believe the glitch you are referring to (and I have confirmed) concerns the GH2.
On the AF100 the glitch occurs on all f stops except wide open at f/2. On the GH2 the iris glitch occurs even at f2 as well as a few other stops.

Go figure : ( I'm not even sure an Olympus lens firmware upgrade can fix this.
 
I had 4 Zuikos (35-100, 14-35, 50-200, 12-60) and recently sold them all -- the iris glitch was one of the main reasons.
 
Thanks so much for your time gents!

I hope some others (if there are other owners with the same issues) join in this announcement...

The Olympus 14-35 is not holding constant f-stop on some Panasonic cameras.

It would be awesome for Olympus to fix this issue.

Yeah yeah, I know, the lens wasn't made for video, blah blah blah...

but

Fact is this is a lens with awesome optics, but the different results seem to indicate we have a firmware problem here, and it doesn't matter if it wasn't made for video, we can take pictures with our Panasonics, and I want f2.0 at 14mm! That's what I paid for!

This is a superb lens for video, and Olympus should welcome the fact that a new demographic (micro 4/3 video) has just been invented for them! Guess what, this lens may be expensive, but not quite SO crazy for the video market... seems to me there are a lot of these new potential clients for them, and they don't even need a new product - just an update to make it do what they say it does.

I still REALLY want this lens, but I prefer it to be working as specified... Olympus is allowing me to return this lens, and providing me with a demo while I wait for a new one, I sincerely hope it works!

As an owner of the Olympus 35-100mm f2.0, I too suspect there's a firmware problem. However, I'm not so sure the problem lies in the firmware that's in the lens. According to the reports in this thread, the lens iris operates differently when mounted in the Panasonic AF100 than it does when mounted in the Panasonic GH2. And when I mount this lens in a Panasonic L1 camera, guess what? It works perfectly at all aperture settings, no iris clicking or exposure variations at all.

While I'm not sure what conclusions to draw about this particular issue, one thing stands out clearly in my view. Panasonic has established a disappointingly inconsistent track record in its support for legacy Four Thirds lenses, both for Olympus lenses and its own Panasonic Four Thirds lenses as well. Check out Panasonic's AF100 lens chart:

http://pro-av.panasonic.net/en/af100/lens_compatibility.html

While the Olympus 14-35mm f2.0 is listed on the Four Thirds lens chart, the 35-100mm f2.0 is conspicuously missing. In addition, Panasonic warns that with all tested Four Thirds lenses, "there are limitations on simultaneous control of focus and iris". This implies to me that Panasonic has stepped back from engineering full-featured Four Thirds lens support in the AF100. Not only the 35-100mm, but the vast majority of Four Thirds lenses appear to be more compatible with the Panasonic GH2 than with the AF100.

http://panasonic.jp/support/global/cs/dsc/connect/gh2.html

Frankly, the dearth of support for legacy Four Thirds lenses is the main reason I've held off purchasing an AF100. I've made a serious investment in Panasonic and Olympus lenses, and they work very well in conjunction with Panasonic's G-series cameras. While the AF100 has a great deal of promise, I'm still waiting for Panasonic to clarify the extent of its commitment to full Four Thirds lens compatibility for this camera.
 
So is the 14-35mm worth buying for the AF100? It seems out of stock online everywhere, which is a problem as well. I wish Panasonic had a 14-30mm F/2 with OS.
