Fullsize real life shots with A6000: SEL1650 versus SEL1670 - can you identify which is which?
8

I think, after all the pixel peeping, doing some real life shots is helpful to see what actual impact differen lenses have on the image.

So I shot the SEL1650PZ and the SEL1670 directly one after the other, handheld, set to f8.

To make this sort of a quiz I have erased exif from the pictures. The pictures are complete except for 20-50% blue sky in the top part which I cut to reduce file sizes and increase download speeds.

Focal ranges are 16, 24, 35 and 50 mm, all at f8, handheld, AWB, central focus point.

Ready? Steady.. Go!

a1 16mm

a2 16mm

a3 24mm

a4 24mm

a5 35mm

a6 35mm

a7 50mm

a8 50 mm

And as bonus at 50mm, too:

c1 50mm

c2 50mm

Any guesses?

my guess is,

a1 SELP

a2 Zeiss

based on corner sharpness.

My guess is that the first shot of each set is the SEL1650. My reasoning is more the color and contrast, I feel that that lens has more of a wash.

This is really fun, I wouldn't have expected that it is so difficult.

Will give others some more time and then spill the beans. At present, only 3 of 7 guesses made are right

I like to pixel peep, but all I can say is they are close enough that I don't feel inclined to wax poetic on inane differences, your 16-50 is good, your 16-70 is not really worth the cost/size, and if I bought a sony system I would cross my fingers and hope I had a 16-50 as good as yours because its quite nice for the size/weight/cost.

On the otherhand f8 is a great equalizer, but your 16-50 looks good nonetheless (whichever of the two sets it is).

I think that you are making a good case in that the E-zoom lenses are more similar than dissimilar...

The E1670Z and E18105G do open the aperture up to f/4 - which may be important to some.

But I agree, unless you shoot professionally, and this is your 'must-have' gear, I think that, for most of us, the E1650 is a great option.

I'd rather add a fast prime lens to cover wider apertures/low light...

I think the second picture of each set is the 16-50mm based on the corner softness which is not drastically different.

Also with the flower shot, the first one just pops a little more IMO.

I probably have it wrong but wow, that definitely makes these lenses look even in those conditions.

@Eric:

wrong, wrong, correct, correct, correct

@kg1128:

Wrong, it is the opposite

@PixelCowboy:

Wrong, it is the opposite way

@John Triebe:

Same as above, wrong, the opposite way around:-)

@Harold C3:

Perfect, the one and only who got it all right!

So it is interesting, that overall much more persons credited the better shots to the 1650 lens, which has happened to me also when viewing more of them on my screen.

@Henry & Timbukto: Yes, of course the SEL1670 (and the 18105) offer f4. The 1650 needs f5.6 to become good at any focal length. So you gain one EV when light is low with the other lenses. And you get lower DOF options when using the tele range.

But whether this is worth the price, weight and size to you, is a personal question. Coupled with the fact that more photos look better at f8 with the 1650 than with the 1670, it is a tough decision.

For those interested, I also have a center/left upper edge comparison 1:1 at different focal lengths to make comparing easier. However, light conditions varied due to the clouds.

This is a small example, for the real thing (10000 pixels wide, 23 MB), the link is on my blog:

Re the flower shot: with the 1670, fl was at 53 mm, which may account for the more pop you notice 😊

Tricky. I think you mixed the photos. My guess:

16mm:  1-Sony, 2-Zeiss

24mm:  1-Sony, 2-Zeiss

35mm:  1-Zeiss, 2-Sony

50mm:  1-Zeiss, 2-Sony

Bonus:  1-Zeiss, 2-Sony

Or not.

16-70: a1, a3, a6, a7, c1 (with loop)

16-70: a2, a4, a6, a7, c1 (with out loop)

The "a" pictures (slight variation in exposure) are so close that I would only choose between them if  I were making large prints.

I think the background on the C1 pic is smoother than that of the c2.

I'm not sure why reviewers give the Sony kit lenses poor scores. This shows how well the 16-50 holds up agains the Zeiss 16-70. I did compare the 18-55 with the Zeiss 24mm, f/1.8 and it also compared very nicely.

If it were not for the difference I see with flower pics and pics of my grandchildren I would not spend the extra $$$. However, in some situation the images of the Zeiss lenses are special.

Or to put it another way, it shows how poorly the 16-70 distinguishes itself from the kit lens.

I (still) can't see paying $900-$1000 for this lens, and (still) think there is a huge niche to be filled here.  Hello, Sigma?  Tamron? Rokinon? Anybody???

Thank you to the OP for posting this challenge.  Most illuminating!

I do find the Zeiss lenses (I now have 3) do distinguish themselves with pics of my grandchildren and flowers. Did take the 16-70 to the botanical gardens and it produces images which are superior to my Sigma 150 mm lens and Nikon 85mm lens. Both the Sigma and Nikon lens are prime lenses and well regarded.

All it means is the ZEISS 16-70mm is not particularly great at the wider end. The later shots where I guessed correctly were all very obvious as to which was the ZEISS as it was much sharper on the outer edge of the frame. The wider 2 shots were harder to identify.

The flower shot I guessed correctly because the bokeh on the ZEISS was better, the 16-50mm had triangular shaped bokeh (barely out of focus plane) from lens aberrations for which the ZEISS is better corrected.

The ZEISS offers 70mm f/4 which adds to the cost, but the 18-105mm f/4 also has 70mm f/4, and beyond, and is much cheaper. I think the ZEISS 16-70mm looks like a nice range lens, but would rather see a Sony G on it and have it sell for less.

I will probably rent the ZEISS lens, I want to see how it compares to the kit Fuji 16-50mm lens.

Without looking at 100% or even zoomin in I'm saying:

a2, a4, a6, a8, c2

Reason being better transmission (aka, slightly over exposed), but I am assuming you kept the exposure at the same levels if not I'd have to look at the images more closely

Edit, just realized I had a different viewing angle on my monitor, may well have accounted for it too
