In Topic: Sony A6500 SEL1018

Hi JB,
 
What is your favourite lens for Sony A6500 if you are shooting wide angle? Macro? and fish portrait?
 
I heard the Sony 16mm with fisheye converter is not good in terms of corner sharpness, what about stopping down the aperture?

On my NEX6 and a6300 I always used the 16+fisheye and, to be honest, never had a huge problem with corner sharpness - not because the corners were sharp, I just didn't notice that they weren't. But since I've been doing a few workshops and rubbing shoulders with the pro crowd more, and entering competitions, I have been more sensitive to the issue. I still don't think it's severe enough to stop me using the lens - as you say, stopping down helps (who needs shallow DoF with wide angle anyway?), but I haven't done detailed testing, so don't take my word for it.

For my a6500 I do want to look at the alternatives, and that's why I'm splashing out on the Tokky 10-17 for my forthcoming Socorro trip. But it will have cost me over £2,000 for lens, converter and Zen dome. TF my wife doesn't read WetPixel (I hope).

I've been using the 10-18 with Nauticam 7" port for some years, and upgraded to the a6500 earlier this year.  The disadvantage of the 10-18 being a rectilinear lens, is that it distorts perspective in a way that can sometimes be quite confusing, stretching the edges of the frame and making the foreground feel vertical, especially when zoomed all the way out.  A couple of examples below.  So it's not the right lens for CFWA and I only tend to use it for over/under splits.

That said, it certainly has its uses, and retaining straight lines, as you might need for deep wrecks, is a good application for it.  Alex's shot of a cormorant (?) diving into a shoal under a rig is a prime example.  It is also good for use with larger creatures that don't like you getting too close, like these of sharks:

The standard alternative would be the Sony 16mm with fisheye converter, which I have used successfully but certainly has quality issues.  Otherwise, I shall be using the Tokina 10-17 with Metabones Mk 5 converter for the first time when I go to Socorro in November (and will also take the 10-18).  People allude to auto-focus issues with converters, but so far it seems to be pretty good on dry land.  

 

Hope that helps.  (I'll be deleting the linked photos after about a week.)

Biggest problem and the end of the discussion (as far as I am concerned)

 

No decent fisheye option...

 

I guess we should also discuss the A7RII's autofocus too!

Tut tut Adam.

 

I've just sorted the Metabones MkV with Tokky 10-17 for my a6500.  Top side, the AFC in green mode is very encouraging, so let's see what happens when I get to Socorro in a couple of months.
