In Topic: AF tips with G7X Mark II

If you look at the work of most u/w photographers, there will be few taking photos of small fast fish.  As you have learned, its not easy.

If you can find a place the fish like to be or dart past often, you might manually focus on that spot and snap a photo when a fish is arriving.  This can work with salt water fish.  I have no experience with fresh water fish.

Faster focusing can often be reached using a focus light.  Focus lights do not have to be over expensive or large but you can spend a lot, just as with most gear.

Your housing has a cold shoe for connecting lighting so you could buy the fittings needed to connect a focus light at that location.

Here is some information below at the link.  Search this site for 'focus' + 'light'



In Topic: Strobe Advice Needed

Welcome to the addiction!

You bought a nice camera and housing.  You said wide angle shots are of interest to you.  Wide angle shots mean lots of light spread over a large area.  That directs toward more powerful strobes set a good distance apart.

If you buy 2 smaller strobes, you will get some degree of coverage and light but not as much as you will want with time.   If you buy a single more powerful strobe to start and limit the bank breaking, you will be half way to what you will really want.  If you buy the smaller ones, you will still be 100% of the way from your ultimate goal.  I started with the smaller strobe path and spent more in the end.  Hoping to keep you from that mistake.

If going new, I would buy an Inon Z-330 with an 8" and 5" arm plus floats to provide lift.  If you can find good used Inon Z-240's, that would work great.  But you cannot tell how many shots have been used with those strobes.  Some people sell the Z240 to upgrade tot he Z330.  I would buy the Z330 and save up until I could afford the second one.

There are other brands of strobes that sell good, powerful strobes at similar or higher cost.  I am familiar to Inon so I will stick to discussing that brand. 
The other brands can be just as good or better and others will likely chime in to discuss ones they know about.


Hope that is some help.  You will find your 2 strobe will cost more than you likely spent on your housing.  YIKES!

Thanks for the information and suggestions.  I downloaded the DNG converter and will give it a try when needed.

How is the shutter lag on the G7X?  Enough to give you some frustration in the field?
