Hi

 

We post updates in the news section on our homepage. 

 

Here is an excerpt from the latest update: 

We expect the first packages will depart at the end of July / beginning of August. The currently pre-ordered flashguns can be expected for delivery throughout August and September.

Please note that our warning regarding the shipping date for pre-orders still stands: "Delivery times may change due to production delays or product improvements. If you are planning a diving trip with the new Retra Flash at the time of the estimated delivery date we strongly advise against pre-ordering! There is no guarantee you will receive the product on time. Your pre-order may be fully refunded at any time. Currency conversion changes will not be compensated in the event of a refund."

 

More updates will follow in the coming months as we edge ever closer to sending out the new products. Right now we are super busy with the pre-production runs.


In Topic: Snoot aiming advice - Retra LSD

18 June 2019 - 11:59 AM

Thank you Tom and Chris for quickly responding to Tim's issue and helping out. Since this topic was started at the same time as Tim sent us his email I said that I will reply here. 

 

If you can see the pilot light clearly and more or less in the center of the beam this means the LSD is mounted correctly which is the most important thing. 

Since Tim already has experience with the LSD on his Z-240 I will skip the basics but if someone is interested here is the topic where most of the beginner stuff was covered: http://wetpixel.com/...showtopic=62595

 

What I would like to add is that masks act as apertures. The smaller the hole the darker the light output and with our masks it goes down about 0.5-1 F-stop per step.

With smaller holes and the Z-240 it is normal to use full power. The new Z-330 is more suited for this because of higher power and the pilot light is slightly tilted making it more central in the LSD which helps with aiming. But still the ideal scenario for snooting is a pilot light and flash tube shining from the same spot or what is more common: a round flash tube with a pilot light in the center.

Hi Oskar, does this mean that the new Retra Pro will be compatible with the typical Eneloops, but you will also offer the proprietary battery pack?  Will this proprietary pack offer half the recycle time and double the number of flashes (like the battery pack extension did with the original Retras)?

Yes, with Prime and PRO. The battery pack will improve recycle time and number of flash, exact figures will be announced when the battery pack is ready for pre-order.

We haven’t tested this yet on the new Retra Flash but Adam tested more than 400 flashes on the original Retra Flash which has 100Ws: http://wetpixel.com/...ymbiosis-ss2/P3
This is quite ideal test situation with new batteries, almost constant room temperature and consecutive firings. In real life there are things that can reduce the number of flash, mainly the temperature and battery age/condition. But we can expect something roughly around 200-300.

Anyway we are working on a proprietary battery pack design which will improve the new flashgun performance (not compatible with original Retra Flash). The new battery pack design will require more intensive work and we aim to confirm it’s design after the new Retra Flash Prime/PRO are already shipping. Specifications will be announced in due course. News on this here: https://www.retra-uw...ra-flash-update

First of all thank you for your extensive opinion, we appreciate the extra input.

 

Lab test in air on a wall with a single light do not really represent real life usage of products because with a single light beam angle is not important

 

Just to clarify, we use studio testing on land because it is consistent and can be repeated relatively quickly without major deviations. But this data is not the sole measure of the quality or the power of light the flashgun produces. We rely on field testing to confirm that something really works as intended and sometimes it doesn't.
