Coming soon from Apple is the recently announced Magic Keyboard for iPad Pro. Like before, it's a combined protective case and keyboard, but this one will have 2 dampened hinges and a secondary USB-C port for passthrough charging. The headline feature though is the inclusion of a trackpad and accompanying, underlying changes to iPadOS and the UI to accommodate the use of a pointing device for navigation. Basically, the iPad is becoming more laptop-like since the diversion from a unified iOS code base to separate iPadOS and iPhoneOS. Now the hardware will begin to reflect that change.
Added a quick link to the header menu as well as sidebar widgets to access the categories menu. That should make accessing posts related to the lens database easier. You may also use the direct address here: https://jetcityninja.com/category/adapting-gfx/
Where the Sigma 85/1.4 is a home run, the 35/1.4 is a bit of a mixed bag. For most people, it should be fine. For some, like me, it's borderline acceptable. For those few, it will be unacceptable. In 35mm crop mode, it works just fine, but for any other mode, it will require a bit of cropping and correction. At wide open, there is a bit more smearing in the extreme corners that sharpen up by ƒ/4 to 5.6.
The Sigma 85mm seems to cover all of the imaging sensor with no hard vignetting. Fitment of a Wine Country Cameras 100mm filter holder does cause some very light vignetting at the extremes but is easily correctable. Image quality at the extreme corners and edges is a bit compromised at wide open but shapes up when stopped down to ƒ/4.
