We have experienced this issue with less than 1% of the units shipped. It is an issue with the spacing of the lock ring and the individual camera.

Hi Ryan,

Thanks for your comments. I think that one of the main concerns would be the numerous instances where the subject may be centered (i.e. Paul's license plate example) where the goal is to have the subject filling more of the frame (thus the 1.6X). It just looks a bit odd to have the plates at one level of focus and the tail lights at another when they occupy the same depth of field.

Could you provide some of the samples that Century has produced in testing this lens that show performance at a near and far point of focus? It would be very helpful in seeing if I am realizing the norm for this lens' performance or an anomoly.

Thanks again.

Ryan,

I and a couple of others here are part of the 1%. Is there any way to fix my 0.6X lens - it vignettes very badly from about 6.5 - 12mm.

Is the only solution a return - and if I do will the new one also vignette?

Look forward to your reply.

Thanks Tom. That was exactly the kind of advice I was looking for! I have actually been impressed with some of the video I have seen others post while using the Sony 0.8x. I am just a little shocked that there isn't a better option yet.

cheers,

I was asked by my local shop to check out and post some images of the new ZUNOW Optics 0.75 Wide Angle adaptor for the EX1. Its not schedule for international release till the fall but its out in Japan now. Ill be going into the shop thursday and will post screen shots hopefully that night. Apparently it has zero distortion and full zoom through but lets wait and see.

[Tom Hardwick]

OK, I'm waiting to see. The Zunow produced for the Z1 was shown at the Video Forum in London last year but when fitted to my Z1 had oodles of barrel distortion. I didn't need to zoom to full tele to check it out further, I didn't want my brides barrelling in the middle.

Let's hope their latest design is better.

Well I guess I am part of the one percent also. I have vignetting from full wide, all the way through to above 10mm. The bulk of my shoots involve the need for a wide angle lens, so this is a problem. Is there a fix from those of us suffering from this issue? I know at one point you stated that you were "formulate a solution"....what are the options available for those of us with this issue? Is it something you are able to address or does the camera have to go back to Sony?

I got a chance to try out the new Zunow Wide Angle Lens here in Tokyo today. Who on earth are Zunow? Good question. They are a small Japanese Lens Maker who stiil hand make their lenses in Akita, Northern Japan. Its hard to get much information on them. They had a wide Angle for the Z1 that, although popular in Japan, seemed to get average reviews overseas.

I'm posting comparison shots with the Sony Wide Angle Adapter. I'm no pro user but here are my comments. Let me know if I left anything out. This Lens is nice piece.

My comments...
Noticeably less barrelling than the sony WA .
Its wider than the sony WA. Its 0.75. Sony's is 0.8.
It IS full zoom through just like the sony WA.
A removable hood unlike the sony WA permanently attached hood.
Heavier than the sony WA, around 830grams compared to the sony's 630grams.
It locks onto the front lens by putting it in position and turning a metal ring to lock position.
Very solid build. The hood is a hard rubber material.
It wont be available in the US until October.
It retails at 98,000 Yen here. That's about $900 US I think. I'm told it will be about 20% more when it hits the US market.
Seems like a better lens than the Sony WA but maybe hard to justify double the price for some people.

My local shop is trying to work something out for anyone wanting to buy one from outside Japan. If you are interested let me know. Otherwise you might try through your local dealer.

Cheers, Alex

Yes, the Zunow does barrel distort a lot less than the Sony, but to say it sees wider than the Sony is pushing at microns. Still, I find Sony's barrel distortion quite unacceptable, so even theough the Zunow is a huge amount of money, it's the one I'd choose from this comarison.

Shooting into the light would test out the flare, though as both lenses are hooded and multi-coated I'd not expect to see much difference between them.

tom.

[Alexander Kubalsky]

yeah, I agree, fractionally wider but the less barrelling is really its strong point. That and the fact you can add a matt box. I panned around and did shoot some shots directly towards the sun actually. Maybe I'll post some stills if any one is interested.
I don't mind the barrelling on the sony. I don't film brides and the Japanese are all so skinny anyway.

Anyone experiencing issues with their lens can, as always, send thier lens in for inspection. However, we can only bring the lens to the specification we manufacture the lens to meet which is based on our testing of numerous Sony cameras. If the lens is found to be within our specifications and doesn't vignette on any of our samples of the EX1, then you may consider other avenues of inspection for your camera.

Hi Ryan,

Thanks again for your responses here. I would respectfully ask again that you post some samples of these lenses working correctly. That will be a much more convenient manner for your customers to guage how their lens/camera combo is functioning, as opposed to a costly and time intensive send-back/inspection period. As you mentioned, these have been thoroughly tested, so it should be a fairly simple matter of posting already existing samples.

Is that not possible?

Randy

Ryan,
I have tried two .6x lens now and experienced similar vignetting on both. I am assuming then it is a camera issue. Can you please provide the information we should pass on to Sony to ensure they inspect and service the correct thing, since I only want to send it in once (if that!).

Thanks

From the samples posted the Sony is a lot sharper than the Zunow, both at full wide and zoomed-in.

FYI, barrel distortion is hard to avoid at this price point. It's something I can live with for the shooting I'm doing.

If I really need to reduce or remove it, that can be done with the help of a filter in After Effects. You do lose parts of the image, however.

Dean, Im not sure if I moved the focus ring when changing adapters. The Zunow was the second one. Although I had peaking on all shots, Im not sure if I had it at max on the zunow. Having said that though, while moving the zunow around and focusing I did find it hard to see any peaking fully zoomed in o another shot aimed more toward the sun. I thought that might have been because I had to close the aperture a little. I wish I'd had more time with it to confirm.
