not fully throughout the zoom range. At 10mm you have severe vignetting, gradually receding until completely gone at about 14mm. from 14-18mm it covers Full Frame. cheers

I always lock AF in place before putting on a 10stop filter. even if it works on the first shot, you may miss it in the next, especially if losing light. And controlling it is not easy - you cannot ...

what exactly do these graphs show? in 50% of your measurements the value decreases after f5.6, but i have yet to see a single lens where visible sharpness corresponds to that. Especially in the ...

did you have 2 identical and seperate setups, i.e. 2x lens/trigger/SD/battery and body? Since it happened on both bodies, then it cannot really be an individual equipment glitch (what would be the ...

are the lens correction profiles from the software suppliers?? as in CaptureOne, LR and DxO all create their own? i somehow assumed they are based on manufacturer information / data, and no ...

well, Capture One added support mid-November, Lightroom and Luminar mid-December... thats 6 weeks ago. if DxO Labs still doesnt support it, they re not exactly early to the game..

here's a Fred Miranda thread comparing the looks with FE 35f28 Sonnar http://www.fredmiranda.com/forum/topic/1392390/22#13262158

not quite :) IF I understand this correctly, f1.4 describes the amount of de-focus which is equal with both at their respective f-stops. however, bokeh is somewhat objectiv to the eye, so a bit ...

T-stop describes light transmission, f-stop describes amount of bokeh, so the f1.4 would have more DOF. Where did you find info that Roki/Samyang have T2.0?

ok, but keep in mind that the r2 will continue to lose value. and if you upgrade to r4 in 2 years you ll end paying about same as if you get r3 now and r4 then. but you ll have r3. thats how I ...

I also do mostly land-/cityscapes. After upgrading 1 month ago: (1) overall Speed makes work more pleasant (2) pixelshift detail is awesome. i dont mind additional ...

I m surprised to get called out for showing an example at ISO320. Pixelshift is about sharpness and detail first, and the test clearly shows a huge difference. I doubt ISO100 would make any ...

just adding the comparison I made as well, including A7r2. This is taken with the very budget FE28. Goes to show that the concept of high MP sensors "outresolving" bad glass is somewhat of a fairy ...

I ran the test and also ended up with Result #3 i wasnt expecting to see such hotpixels that remain in place, even after powercycling and changing date+powercycling. they also show up on 15sec ...

i sure did, especially after this plot twist: on the 6th day i got message, we have your bag, it will be delivered in 1 hour.... 5 hours later waiting at hotel, knock on the door. guy with a ...

adding my lost suitcase story flew to Hong Kong via Paris last year. i got lazy and packed new laptop XPS15, A7rii + 4 lenses into luggage, so i wouldnt have to carry it around. It took AirFrance 7 ...

I have a had the ZUIKO 50s and espcially the 1.8 is great deal, but my favorite is ZUIKO 24 f2. very short minimum focussing 25cm and nice bokeh. i use it regularly on my A7r2 both for stills and ...

are you saying the spot is above the vase regardless of you holding the camera in landscape or in portrait orientation? Then that would prove the spot is not caused by the camera hardware. To me it ...

Here is a good summary of what the benefits are https://www.dpreview.com/articles/6144418951/what-difference-does-it-make-sony-uncompressed-raw i shoot important stuff uncompressed and try to ...

that's why i created this thread, I d like to know how much of a difference we are talking about :) maybe do a test with same lens from tripod in M with identical settings would settle it..
