Coming to a threatre near you. 
Seriously I’ve been getting lots of requests for lens tests and comparisons.
So I went out this morning and shot my bag full of glass. I’ll be posting the Raws of each lens. I do have excellent copies of each as well so this should give a idea of resolution, color, detail and such. These are all mid range distances all with the exact framing so you can download and compare against each if you want to.
Lenses Tested
CV 15 f4.5 E mount.
CV 21 f3.5 E mount this is the new one
Sony 24mm 1.4 new as well
CV 35 1.7 Ultron M mount both with a PCX 5000 filter and without. Visible difference
CV 50 1.2 M mount this is also new
So in these test I shot wide open than next full stop down. Example 3.5 than F4
You will have Exif data for all except the 35/50 and I’ll give you apertures in order.
I’ll have these up ASAP but I have a busy next two days but I want to get them up soon.
I’ll post at least a Full frame image from each. This will show color, distortion and such and post Raws if each lens
I made a lot of changes to my lineup so this will help me and hopefully help others trying to decide what they want
This should be fun

One thing of note we know how well the Sony 24 tested here so that maybe a good standard to compare against. I’ve done most of these lenses already but never at the same time if day or date. So all this should be fairly equal. I waited till the top of the building was well lit. Which is what we look at anyway. I started early and all set to daylight in camera so nothing shifts on us

Voigtlander Super Wide-Heliar 15mm f/4.5 Aspherical III Lens for Sony E
Okay lets start with the CV 15 F4.5. This is the first lens of the day so color is kind of warm. I was out early and I waited for the tree shadow to at least get past the center. Here you really have 2 choices when it comes to 15mm primes . The CV 15 is the smallest between it and the Laowa 15mm which is a F2 lens and much bigger. In all truth you cant go wrong with either one of them. Really depends on need , Im after small for travel and city work.
Now here it is at F8 which is really good thats all it takes to get good across the field actually check F5.6 as it is quite good also. You get the Raws so go for it.
I also did the distortion correction on second shot. Looks mostly barrel

Voigtlander Color-Skopar 21mm f/3.5 Aspherical Lens for Sony E
Next is a new one to the market and for me and love this thing. Its very small and lightweight and one of three lenses to look at in this focal length. Tokina Firin 20mm, Loxia 21 and this. The Tokina is quite good and sharp but my opinion a little on the clinical side. Loxia 21 i did not test directly against this but Fred did. Its kind of a toss up. This CV is so very close it makes it a tough call. The Loxia will win on micro detail but again here you can save money and save size. Personally Im not a fan of Loxias ergos with the aperture ring the same size as the focusing ring and the focusing ring has no tactical feel to it. I like the CV becuase of knurled focusing ring and aperture ring is out front. Personal choice . All good lenses

So I was a rotated on this series. So I straighten the crop out than did the normal process than corrected that. Than on the Crops I reset it back to the original . That way we are not cutting off those corners.
These are at F5.6. Very Good here

Sony FE 24mm f/1.4 GM Lens.
Been the talk of late and it is a outstanding lens. Here at F4 its awesome across the field. Here you have Three choices the Loxia 25, Batis 25 and this. I tested this and the Loxia 25 and its damn close. The sony has the advantage of F1.4 and being awesome across the frame at F4. The Loxia has nicer sunstars and maybe better flare control. Several threads on this so look for those on that comparison. Im including these today as a standard to compare against

Voigtlander Ultron 35mm f/1.7 Aspherical Lens.
This is a Leica M mount lens
In this series a added Front Filter has been added to correct for Field curvature and in turn gives better mid zone and corner detail. This does add one problem when adding the front filter it also affects infinity focusing distance so what you need is a Leica M to Sony e adapter that is slightly thinner in depth. I have a Kippon and a KF adapter and neither one will do it. Okay so what am I supposed to do. Well there is a trick the 35 does have a rear element group that you can unscrew and inside it has 2 shims, problem is you need 3 to get the element closer to the sensor. Right now Im not tightening down the rear element and thats giving me infinity. I ordered another adapter to try. Worse case i will file down the cheapest adapter and try that
So there is no EXIF here so when you download the Raws. It will be in order 1.7,2,2.8,4,5.6,8,11
You could easily do F6.3 as well for corners

This is at F8 with no PCX filter and as you can see as a raw lens on a Sony sensor stack it is soft in the corners compared to the one above

Voigtlander Nokton 50mm f/1.2 Aspherical Lens. This is also a Leica M mount. I found this lens to be very similar to the now famed CV 40 1.2 in E mount. I actually like this better as its a little sharper on center, has nicer rounded bokeh and a little length for people type work. A E mount is coming. I cant wait that long.

This was a good test for me. Finally got to see where everything is falling and I’m really happy with these results. Right now unless there is a E mount 50 which to be honest not sure I should switch as this one performs they way I like. The AF side is 24, Batis 85/135 and on the block maybe my Tamron 28-75 which is a great copy but I’m not a zoom guy really

I’ll probably go out more with the CV 35 1.7 Ultron some more as I just got that and want to see more from it.
Anyone have questions please let me know.

Many thanks Guy. You help me on with my decision on the CV15. Looks like the 21 has slightly better corners, but overall performance is similar. 
The ultron with the PCX seems to be winner as well...
