In Topic: Are you happy you changed from DX to FX?

31 January 2016 - 03:41 AM

Another thing to consider is the quality of Nikon's FX lenses vs their DX lenses.  As I look through the lens tests on the German website PhotoZone.de, and compare the Nikon 105mm f2.8 VR Micro-nikkor vs the Nikon 85mm f3.5 (non-VR) Micro-nikkor, the resolution results they show indicate that the 105mm f2.8 lens out resolves the 85mm 3.5 significantly (by about 20% or more) at the apertures (f11-f22) that would be most useful for macro shooting.  Comparing Photozone's test results for the Nikon 16-35mm f4 VR vs the 10-24mm f3.5-4.5 (again non-VR) the resolution numbers again favor the 16-35mm by about 25% at most apertures and focal lengths.

 

This is not surprising.  Nikon considers FX their pro format. The FX equivalent lenses are more expensive and physically larger.  And better optically.  So if you want the best image quality from your Dslr, FX is the way to get it.

Hi Adam,

 

I didn't mean to suggest that I wanted to trigger my strobes wirelessly, only that I wanted an independent flash compensation control in addition to the general compensation. I'll have to re-examine the pictures I've seen of the D500 to look for this on the zoom out button.  The flash comp control is one of my most used controls on my D800 housing.  To the best of my knowledge, neither the Nikon D3, nor the D4, had this.

 

The ability to have a "remote" strobe that can be triggered wirelessly, in addition to one or several strobes directly wired to my housing is something that I do use occasionally.  For this need one of my old Ikelite TTL slave triggers works very nicely.

One thing to note on both of the new cameras, the D5 and D500, is that from the pictures I've seen, neither camera has a flash compensation button, only a general compensation control.  This would make shooting TTL flash quite difficult if every time you wanted to change the TTL output of the flash you had to go thru various menus to do it. And in this case any change in the flash output made by using the general compendation would also affect the ambient light exposure if you are in any auto-exposure mode rather than manual mode.  

 

Increasingly, when I am shooting pictures that have both an ambient light component to the picture and a (fill) flash component, I am shooting in either shutter priority or aperture priority auto exposure and using the flash compensation to control the strength of the fill flash relative to the ambient light rendition of the background.  It works so well that I joke with friends about having turned my D800 into a point & shoot camera. Shooting this way allows me to get more of the one-shot opportunities than ever before and get the shot when the ambient light is changing rapidly.  

 

How you would even be able to link an underwater strobe to the camera and shoot TTL may present new problems to the strobe makers since as far as I am aware, radio signals do not transmit well underwater.

In Topic: Use my days at Kri Eco in Raja Ampat

Hi Everyone,

 

I made it to Bali and was able to get in contact with DAN.  And so far they have been very supportive and very helpful by recommending an ophthalmologist for me to see.  The diagnosis is conjunctivitis, which I'm now treating with prescription eyedrops and an oral anti-inflammatory.  So the medical situation is now under control and DAN has been very helpful. And has my thanks.

 

Concerning my idea that I might be able to give someone else my unused days at Kri Eco since Kri Eco was unwilling to refund any of my money.  DAN has ruled this out.  Or ruled it out if I want to make a "travel interruption" claim for reimbursement of the unused portion of my time at Kri Eco. Since the amount of money involved is several thousand dollars, I do want to try to recover whatever I can.   And, unfortunately, my DAN policy will not allow me to give the days to anyone else. 

 

My apologies to everyone who took the time and effort to write to me asking about this possibility.  And my tank you's for their get-well wishes.

In Topic: Full Frame SLR wide angle corrector port tests

26 November 2015 - 10:44 PM

I would be interested to try this Sea & Sea corrector lens.  Can someone please tell me if this is a currently available Sea & Sea product and what Sea & Sea's designation for it is?  I would want it in the appropriate size for use on Nikon's 16-35mm f4 VR lens.  Does anyone know where I can buy one?

 

Thank you,
