Nobody knows the actual maker's name of most generic 

products. My own bellows are labeled as "Accura" and 

"Vivitar". I formerly used Hasselblad and Nikon bellows, 

and I seriously doubt that 'Blad and Nikon actually made 

those units. All of these can be used on Sonys, cuz they 

are the most adaptable type of cameras around. There's 

one brand that we actually know makes there own, and 

has been know for that for many decades: Novoflex. Do

check out their product line.  

  

A Nikon bellows is also a good bet. It uses Nikon mount

lenses, prolly the most common optics available. Expect 

to buy a lens or two for your bellows. It's pointless to use 

a bellows with regular camera lenses. You might choose 

to use M39 screw lenses, which includes many lenses 

made for enlargers.

There is a huge array of bellows lenses out there on Ebay, depending on the bayonet or adapter you are using.

If you buy a Minolta bellows, there are a small range of bellows lenses available reasonably priced, or you can buy

quality Rokkor wide angle lenses cheaply.

   The most important factor is a quality tripod and a remote trigger, alternatively you can use the inbuilt timed delay portrait trigger

The most usefull of all bellows is the Minolta Compact Bellows. ( do a search on google) it is super compact and a joy to use.

If you are super serious about macro the consider the Minolta Bellows mk 1V AUTO BELLOWS 3, it has the ability to alter the focus planes

and bring the subject are more into the focal plane.

Good luck, it's a brave new world that macro stuff.

    • Problem Description – Sony ZV-E10 II A few weeks ago, I purchased my Sony ZV-E10 II camera from Digital Photo Supply. The unit is updated to the latest available firmware and is showing an abnormal behavior in the continuous autofocus system (AF-C), which can be consistently reproduced under different conditions and with various native Sony lenses. Observed Symptoms The parameters for focus transition speed (AF Transition Speed) and subject shift sensitivity (AF Subject Shift Sensitivity) do not remain stable. When the camera encounters a point or surface with low texture or contrast and takes time to focus, instead of maintaining smooth “focus breathing” according to the settings, it makes a sudden jump to focus. From that moment, autofocus behaves as if the speed were set to the highest value, completely ignoring the configured settings. After a few seconds, or when reframing, the system resumes normal operation. This phenomenon occurs even with Active Stabilization, Face/Eye AF, and Touch Tracking turned off. Testing Methodology Tests were conducted under various lighting conditions, both high-contrast and flat light. Different subjects were positioned at varying depth distances but laterally aligned (scenarios with partially overlapping elements). Medium and low focus transition speeds and medium or low subject sensitivity settings were used—these are the cinematic parameters I normally work with. All tests were performed exclusively with native Sony lenses, varying light and contrast levels to check behavioral consistency. Under these conditions, the camera consistently showed instances where, when using Spot Focus (S/M/L), it would momentarily lose focus and, upon regaining it, start focusing instantly on any new subject as the camera moved—completely ignoring the configured transition speeds. Control Camera Used A Sony ZV-E10 (Mark I) was used as a reference with identical lenses, settings, subjects, and lighting conditions. It passed all tests successfully without reproducing the issue. Impact on Professional Use This malfunction is catastrophic for my professional video work, where precise and fluid focus transitions are critical. When the system ignores transition speed and sensitivity settings, the footage becomes unusable, directly affecting visual continuity and cinematic quality. If this behavior cannot be corrected, the camera is unsuitable for professional video use, as it compromises focus system stability and predictability.
