Topics I've Started

Diopter

28 June 2015 - 05:04 PM

I am going to take a deep dive into macro photography and I had a couple questions about diopters. If I am shooting something as small as a nudibranch with a 85mm macro lens (Nikkor). Is a diopter still needed?

 

Does someone have a shot with a diopter and without one for comparison?

 

Also can I use AF with a diopter?


Life of a Strobe?

09 June 2015 - 06:06 AM

I have searched the internet and can't find anything on this topic. Can someone give me an idea on the life of a strobe or at what point a servicing is needed? I bought a pair of YS-250. They look great both fire but as I mentioned in my previous post I am struggling with them. I can't seem to get any power out of them. Flash on the camera is set to manual But I have to be right on the reef to get a shot. Keep in mind I am moving up from a 4/3 system shooting in live view.

 

The previous owner had them for about three to four years and used them maybe 8-10 times a year. I can't imagine that is any usage on these strobes. Again both fire, seals are good.

 

Am I right in the assumption on the usage or should the be sent in?

 

Or is it I am expecting to much? Maybe I am asking the wrong question.

 

At what distance will these strobe fully illuminate a reef? 

 

Thanks for any help.


Question on strobe power and Syncing with Camera D7100 YS 250 Strobes

04 June 2015 - 03:53 PM

I just got back from a trip to Coz with the rig that I put together. Nauticam housing Dual YS 250 strobes triggered through fiber optic cables. I really struggled with the strobes. My first quesiton: I should set the camera to manual and not TTL correct. I am asking this but I am pretty sure on this one.

 

Second is it possible that the strobes could some how not put out full power? Both fire just fine but they didn't seem to put out any power. If I was just a small distance off the reef I got almost no lighting. I was using 1/125 and F8 a lot not a really fast shudder speed or small apature. I adjusted the strobes and had to crank them all the way up.

 

I called a Sea and Sea rep and of course they want me to send them in but I was hoping to get some insight from the group. If the strobes are firing can it be said that the issue is not with the strobes?

 

Also the person I bought them from shot them TTL I shot them with fiber optic cable.

 

Another question if you had the option of shooting TTL or using a vacuum pump system to seal the rig which would you choose?

 

I appreciate any help.

Thoughts on pricing in the forums

05 March 2015 - 08:01 AM

I had a general question for the forum shoppers and sellers. I have purchased a few items and plan to sell a few items. Is it unreasonable to expect a 30-40% price reduction on a used item? Since the buyer assumes all the risk and is receiving an item with no warranty for the most part. 

 

I understand that there are variables such as gently used and so on. Also that it is everyone decision on which deals to accept. I am just trying to get a general concenses.
