EX1 wide angle and Telephoto lens at DVinfo.net

Paul Cronin · April 15th, 2008, 08:19 AM

I just received a shipping confirmation that my Schneider Optics wide angle and telephoto are shipped.
OHD-75CV-EX1
OHD-16TC-EX1

I will post a few stills and a short clip of each if anyone is interested?

Please do Paul. A simple perpendicular shot of your TV screen's surround at full wide is a great way to show if barrel distortion is a problem.

Paul Cronin · April 15th, 2008, 08:31 AM

Will do Tom I will post a few stills when they arrive.

More than interested Paul. Can't wait to hear your impressions.

Alexander Kubalsky · April 15th, 2008, 07:39 PM

Would love to see some stills too Paul. Thanks.

I would love to see two identical shots, one with stock lens full wide and one with wide angle adapter at full wide just to see real world difference. I have a Century Optics wide for my SD camera but that really needed it for sure... I think I want one for the EX as well but need to see a sample of the results first.

Thanks!

The wide angle arrived late yesterday and I expect the telephoto today. I will be editing with a client most of the day so it will not be until tomorrow until I can post some stills.

My first impression is nice build quality from Schneider Optics. I would expect a high quality product having owned three lens adapters for my GL2, Z1, and A1’s. The WA came packaged in a box in the leather pouch with caps on both ends. To connect the lens it is the same as their other lens with the yellows dots and it locks in nice and smooth. I am pleased my Century sunshade with 4” x 4” filters fits great. The filter tray is ahead of the microphone so no problem changing filters while the sunshade is attached. Of course you could always set it up to come out from the bottom if a shot gum mic was being used and you needed the clearance.

I will set up both my EX1’s side by side tomorrow and shoot a few different clips so I can post close up and longer distance shots to compare. Sorry for the delay but work first.

More tomorrow Thursday

Well I have results but I can not upload files. I am only trying to upload six .tif's that are 5.9mb but it fails if it is one ore 6 pictures at a time. So once they have the server fixed I will post results unless someone can show me how to solve this problem.

Also telephoto has arrived and I will do a few test with that today/tomorrow.

Paul Cronin · April 17th, 2008, 02:49 PM

I keep coming back and trying but no luck uploading.

Have I been shut off from uploading for some reason?

Dave Morrison · April 17th, 2008, 02:55 PM

Can you post .jpg's instead?

Alexander Kubalsky · April 17th, 2008, 05:08 PM

Don't know what the problem is but i hope its solvable. Cant wait to see some shots.

Jason Bodnar · April 17th, 2008, 05:14 PM

Yes, I can not wait either... Does the Century Sunshade mount with the WA in place? is there a pic of that has well?

Paul Cronin · April 17th, 2008, 05:49 PM

The sunshade fits fine with the WA. I tried .jpg and still fail to upload. Not sure what is happening to bad since the stills reveal a lot. I am sending my WA back since I can not grab focus on the outer edges. Maybe the guys are to busy at NAB and once they are back we can get this resolved.

I will check in the morning to see if there is input on how to solve this problem. I have been uploading for two years most an most of the time with out problems. All files are within the limits and they view fine on my MBP and PM.

With two quick test the telephoto looks fine.

Alexander Kubalsky · April 17th, 2008, 11:37 PM

Paul, So you are not happy with the Wide Angle Lens? What was the problem, Its blurred on the edges?

Paul Cronin · April 18th, 2008, 05:42 AM

Here is my test of the Century WA lens for the EX1.

I did a test this morning and thought the results were flawed then I did a second test this afternoon with the same results. The morning test was two cameras side by side with better background so I will post the results of that test. In the next post I will put the pictures from the afternoon test. All pictures are .tif right from FCP 6 to keep as much information as possible.

There are six pictures three with stock lens and three with wide angle from 12 feet, 24 feet, and 48 feet.

Settings:
MF
ND2
1080p 30P
5600K
-3db
1/60

I am focused on the left door in the middle of the wood. I did try the WA option in the menu but there was no change in the results.

I am very disappointed with the distortion of the WA. No matter how hard I tried I could not get the outside edges of the frame in focus. And at 12’ the distortion is huge just look at the upper left corner. I don’t know if I have a flawed unit or not. But why have a WA if you can’t use the whole frame. My lens is going back to the dealer.

This surprised me since my last three WA lens from Century were excellent

I have a email into Chris to try and solve the upload problem. Once that is solved I will post the 12 pictures from the two test.
