Moar tests. I do have a 58mm ND 1000 filter on order. Meanwhile I returned the 3.5x tele to B&H and substituted 2 different lenses. One is a Digital Visions 2.0x and the other is a Vivitar 2.2x.
5MP oversamples for all...
Here's a manual focus shot straight from Lumia 1020. I focused on the near end of the L shaped building (center of the shot).
I then attached the 37 > 58mm step-up ring to the 37mm Neutral Density 4 filter to cut some haze and glare and mounted this to the BeastGrip. Here's a manual focus thru the ND4 filter.
And manual focus, ND4, max zoom on the 1020.
I think the shot looks better with auto focus. Better color balance.
I actually grabbed the Vivitar tele and the wide angle when I first went out. I had to go back inside for the Digital Visions so the framing looks different on this one from the others. ND4, manual focus 58mm Digital Visions 2.0x tele.
Almost as much vignetting as the discarded 3.5x Panasonic tele (see post
#58 above), but way less loss of focus outside the center of the shot.
Here's ND4, manual focus, 2.0x tele, max zoom from the 1020.
I think the Vivitar 2.2x tele comes off slightly better.
Here's ND4, manual focus, 58mm Vivitar 2.2X tele.
Way less vignetting than the Digital Visions despite a slightly longer barrel and the center of clarity is larger, IMHO.
This one is ND4, manual focus, 2.2x tele and max zoom from the 1020.
I might get some usable crops out of the Vivitar when using the 34MP DNG files.
By the by... I set up a quick shot for you to see the 37mm 8 point Star Filter effect.
By rotating the filter in the mount you can change the angle of the rays...
