أداء وملاءمة Heden M21VE follow focus محركا لمختلف أنواع العدسات
مضى على هذا 12 سنة. قد تكون المعدات والأسعار قد تغيّرت منذ ذلك الحين.
ما توصّل إليه النقاش
- ومحرك M21VE صغير وخفيف الوزن، مما يجعله ملائماً للسيطرة على اليريس و عدسات حديقة الوزن الخفيف مثل أوبتيمو وآلورا لوز.
- The M21VE struggles with heavier lenses such as Primo primes and large-diameter focus applications due to lower torque and longer calibration times.
- The M21VE successfully operated on new Primo V lenses in testing, though performance may differ on older or stiffer lens examples.
- The M26VE motor offers more torque than the M21VE and is better suited for focus applications on stiff lenses.
- On smooth lenses, the M21VE-L may achieve faster speeds than the M26, but the M26 performs better on stiffer lenses that require higher torque.
- Heden service from Sweden provides fast turnaround, typically one week round trip including overseas shipping.
- Direct purchasing from Heden is significantly more cost-effective than buying through North American vendors, though current policy may require purchasing through authorized distributors.
- The M21VE has a relatively small gear requiring longer calibration time on larger diameter lenses, but operates at acceptable speeds once calibrated.
يعتمد على
- Performance comparisons are based on limited field experience rather than extensive long-term testing.
- Motor performance varies depending on lens condition, age, and stiffness, with newer lenses easier to drive than older examples.
- Availability of authorized service in North America appears limited to specific locations.
- Direct purchasing from Heden may no longer be available as of the thread's final updates.
- No comprehensive comparison testing between M21VE-L and M26VE models was completed during the discussion.
