EF lens adapters
 
Does anyone know how you would control the aperature on a Canon EF lens when using a mechanical adapter? Is the lens wide open by default?

Ken Tanaka July 14th, 2003 10:15 PM

I'm quite sure that the Canon EF Adapter facilitates electronic coupling of an EF lens to the XL1/XL1s. As such, you would use the iris control on the camera's body to control the iris, just as you would with the 16x Manual Servo lens or the 16x Auto lens in manual mode.

Jaime Roman July 15th, 2003 07:23 AM

Hey Ken,

I was referring to an adapter like the mini 35 with the EF mount.

Jeff Donald July 15th, 2003 08:21 PM

It is only controlled electronically. EF lenses do not have a manual aperture ring.

Ken Tanaka July 15th, 2003 08:59 PM

Jaime,
I don't believe you would use the Mini 35 with an EF adapter. The Mini 35 is designed to adapt the XL1S for use with 35mm prime film lenses which do not have servo-driven iris controls. You would run the iris from the lens barrel.

As in, 35mm motion picture lenses, quite a very different thing indeed from 35mm still photo lenses. Hope this helps,

And really sweet . . . right Chris?

EF - lens test images (35-350 and 3X)
 
Hi People,

Today was Christmas in July, I went out for the first time with my new 3X lens, and EOS 35-350. I saw in the image gallery a piece showing the 100- 400 in action that impressed me so much I had to buy my own lens for an upcoming trip to Africa.

I opted for the 35-350 instead, and love it!! I thought I would share my first day with you guys with some images.

How wide is the 3x lens, and how about a 2485mm lens, well look here. I bought my lens used which saved me a bundle, and they work great.

Enjoy,

Michael

Great pictures. Im a big fan of the 3x Wideangle, but as yet have no experience with EOS lenses. Keep up the good work.

Nigel Moore August 1st, 2003 05:40 AM

Michael, thanks for this comparison. It's just the sort of thing that's needed to demonstrate exactly what these lens variations mean in reality.

Very helpful indeed.

Ivan Hedley Enger August 1st, 2003 06:45 AM

Second that one Nigel. I hope to se more of this kind of comparisons. Well done Michael, and have a nice trip to Africa.

Clip
 
I've just shot a short, and achieved good DOF using seven Zeiss prime lenses and the 35mm adapter. Here's a short montage of clips--look at the CU of the gun against the actor's legs--

XL1 with EF Adapter & 100mm Macro Lens
 
I want to fill most of frame with a subject that's about 5mm long

How will the above setup cope?

What alternatives are there, preferably still using the EF adapter?

Thanks

Gareth
