Did you mean you are unable to focus to infinity? If so, these infinity adjustment instructions on the Metabones web site may help....

We were wondering if Pentax users want a more affordable, quicker-to-market product without an integral aperture ring, or a slightly more expensive product with an integral aperture ring which...

Disclosure: we have a business relationship with Metabones. On one hand I am an "insider" and on the other hand please take note my viewpoints are likely biased because of this relationship. I did...

In a nutshell, "speed" here means, keep ISO same, your fastest possible shutter speed (for correct exposure) is one stop faster with Speed Booster than without.

Yes, I tried and have to modify my EF Speed Booster slightly in order for PK lenses to fit via a PK->EF adapter, because of the PK aperture lever.

In "Green Power Save" mode, the mode with autofocus, the Smart Adapter or Speed Booster emulates a LA-EA1. The supported feature set is the same as LA-EA1, which is decided by Sony. If Sony decides...

The Metabones Speed Booster has a number of data integrity checks to make sure information returned from the lens makes sense. This is done for the cinematographic community where lengthy...

Regarding the amount of light getting in: same lens, aperture = wide open, same ISO, the shutter speed is faster with Speed Booster than without.DoF: the easiest way to give an answer is that you...

I am not 100% sure about that... if we take the sharpest lenses at their optimal apertures (diffraction-limited) and the sensor still outresolves that, then we would be perfectly safe from moire.

I made a web site about how to do the circuit modification. Some soldering is required. Please email coneos at conurus dot com for the web site URL and also I would need to mail you the component....

You are right. An unqualified utterance of the term "focal length" shall always denote the physical quantity.

"35mm equivalent focal length" is a quantity describing FOV, which is not focal length...

It requires the replacement of one SOT-23 surface-mounted component. We will have to mail you that component. Give me a couple of days and I will try to put together a web page with pictures and...

I "proof-read" again but I am not able to find anything that is outright wrong, although it is true that it could have been made more clear. As always, it is the confusion between "physical" focal...

I have concluded my investigation and ready to report my findings.A slight modification to the circuitry is required to operate in extreme cold weather. Please kindly send the adapter back to the...

You are right, a solder joint fissure can't possibly be camera-body dependent!But your observations have given me some vital clue required to solve the jigsaw puzzle. Thanks a whole lot! I now have...

I speculate that they may have given up. Development costs are high, market is small, and there are many competitors. Lesson learned: do not take pre-annoucements too seriously until the product...

I am charged with looking at this cold weather issue for Genesis, but it seems that there are at least 4 cases with the same problem. My initial conjecture was a fissure in a solder joint. When it...

Did you deal with Genesis Matrix Video? We are working with them on a problem case about a cold weather issue where the adapter works only indoors but not outdoors in cold weather. They are working...

Had same idea and asked lens designer Dr Brian Caldwell about it, and the answer was, unfortunately, no. The glass elements would have to move to be able to autofocus a manual focus lens like the...

Had same idea and asked lens designer Dr Brian Caldwell about it, and the answer was, unfortunately, no. All room available is already used up. If we change the current optical formula to create...
