For reference, Inon makes a "Lens Arm" for this configuration. However, close-up lenses only.

In Topic: INON Z240/D2000 Type 3 -- Only compatible with Eneloops

14 March 2008 - 01:06 AM

I checked with Mr. Miyashita at Inon Japan on this.

Only difference between Type 2 and Type 3 is LED focus light, which emits more heat the previous Xenon bulb. The main issue is heat.
The 3W LED increases total heat load on circuit unit. Considering the total heat load when using conventional NiMH batteries, Inon decided to limit recommended NiMH batteries to less heat emitting eneloop type, and keep the existing focus light continuous burn time and strobe repetitive flash limitations, rather than making them more strict.

As noted by others, eneloops offer various conveniences over conventional NiMH, and the current lower mAh specs are still completely adequate for most u/w situations.



Addressing the other thread, here is background on Type 2 / Type 3 etc.

Z-240 model history

1) Z-240 (original model)

2) Z-240 Type 2 (also D-2000 & D-2000S were upgraded to Type 2)
Circuitry upgrade for compatibility with Nikon D200/D80 when used with fiber optic cable.
Before D200/D80 models, Nikon only used one preflash and one main flash. But from D200/D80 Nikon changed to where preflash can be one or two times, depending on shooting conditions, followed by main flash.
This upgrade is only relevant for fiber optic configurations, and specifically for S-TTL and External Auto Modes.
Besides this circuitry modification there were no other changes.

3) Z-240 Type 3 (also D-2000 upgraded to Type 3)
Change from Xenon filled bulb focus light to LED focus light.
No other changes to strobe.
However, due to increased heat from LED, only compatible NiMH batteries are eneloop (HR-3UTG). Operational limitations on using focus light in continuous mode, and limitation on repeated flashes are same as previous models. (see two .pdf attachments)
