Hi
Anyone is using the Big_is chiped adapter? (EMF chip)
Iīm using it with the 35-70 on a 1Ds MKIII body, and when I attach it to the camera the aperture get stucked at f1.4, and I canīt change the aperture with the camera dial in manual mode to enter program mode of the adapter chip.

I apreciate any help

Thanks in advance.

The best solution (as much as any adaptor-mounted lens can be) is generally held by afficionados to be the Fotodiox. You are very likely to get the best results out if it, and you have to feel you are worth it for the unalloyed pleasure of using a CZ lens on a modern Canon.

What I am waiting for is the definitive EOS adapter shootout, comparo, smoke me out...everyone has the same questions and still it remains a black insider's art. Can I get away with a cheapie? Which one? Are the expensive ones worth it? The optical system breaks down without a high quality adapter, and it already adds a non-design factor to weaken the factory designed/developed bayonet-body join, a very refined effort. (Same issue for NEX, etc. except when heavy/large lenses are used, extra load is placed on the mount design and its resistance to flex.)

This should be pretty easy: get a starting list of popular contenders, decide a sound methodology, pick a wide, a normal and a tele, and shoot MFD and infinity, then pixel peep away...check the slop and fit, quality of materials and finish; has anyone done this? The age of alt lenses is upon us, whole formats are being helped along substantially by them, makers are encouraging adaper use, Sony released the NEX with 1-2 lenses, doubtlessly believing enthusiasts will want to mount their M lenses etc. instead. Adapters are here to stay.

Not too many nice shots, TooManyShots, always room for more like those.

Just got this lens last week and testing at London Chinatown.

Nice shot Robinlee.

Here's another night shot, very early am in Boston on Sunday

Cheers mcbroomf, however your's better

While I agree that Fotodiox has been better than 'generic' adapters I've tried, I do not consider them optimal and would really like to find a source for better models.

In the case of their C/Y adapters I've had problems with the spring piece that 'locks' the lens into the adapter. I had to bend the piece to make it tighter just to keep the lens from coming loose in the mount while turning the focus ring. Even after bending, the piece usually comes loose while remove the lens+adapter from the camera.

I have also found that the more expensive pro line has been fine with all 3 of my C/Y lenses while the cheaper series of adapters gave mirror clearance issues on full frame.

The Fotodiox Pro adapters are significantly better that the 'just plain' Fotodiox adapters. The best adapter that I've tried (but not bought) is from Novoflex. The one I tried was Leica-R mount to EOS, and it fit like a shrink-wrapped glove. Unfortunately, it cost about 1/3 as much as the R 90/2 that I bought.

OTOH, the Leitax mount replacement system is most excellent, and costs less than a Novoflex adapter, although it does take a few minutes to attach. I use the Leitax F to EOS kit on a Voigtlander 20/3.5, where the high precision of the Leitax system really pays off.

Getting past mid-winter and a little color is starting to return - about 50mm f11

My apologies - it was Novoflex adapters I meant to say earlier on, for Canon DLSRs. One from last trip away.

Another.

philip - both shots are spectacular!

Sneaked out my Canon with 35-70 yesterday during a Nikon Photo Safari...

I've found this lens to do quite well for my first stitching experiments. 5x5 image pano (original has ~108MP), shot at 70mm/5.6 with Fuji S5 Pro using a polarizer.

The bottom image is a "100% crop".

Another one ...

Nikon subliminal advertising?

It looks like the wrong message in that case...a torn down, prone on the ground, discarded, tawdry sign - denoting that it belongs to yesteryear - with a beautiful bird all but eclipsing it totally, in a lovely image shot with a 30 year old Zeiss lens.

What do you mean? It is a 100m long banner, being pulled behind a plane in the nightsky, well-lit by the well-funded campaign, putting another nail in the Canon coffin

Pe'epe'e Falls - I may have posted this before, still...

My wife and I couldn't get close enough w/o taking a dip. Water was kind of high.

First shot is the original, second is my crop from that image.
