My old HTC M7 developed the pink purple tinge fault that is common as the camera module over heats and becomes permanently damaged. So I bought a replacement camera module on eBay for £9.99 watched a couple of Youtube videos and had the new camera fitted in about 30 minutes. Fired it up, and hey presto camera works a treat now.
You can check out the HTC M7 camera modules for sale and these Youtube videos will show you how to replace the module.
This is the only way to correct the pink purple tinge problem. Software and setting fixes are a waste of time as the module is fried.
The Voigtlander 15mm super wide is a fantastic lens to look at and no-doubt performs like a trooper when matched with a film SLR but is not so great when paired with a SonyA7R. Due to the lens being so close to the sensor even when using an adaptor to E mount it produces a very strong green at the edges.
The first problem I found was with an E mount adaptor the lens did not screw on without being slightly offset. This caused a problem in the small attached hood of the lens was in the frame when I took a photo, I thought a way to get around this would be to use a small rubber circular washer so I could align the lens correctly. That worked great but the extra couple of millimetres travel sent the focus off on the lens. So even when set to infinity pictures where very soft.
It is a fantastic looking lens and would have made a great point and shoot everything when set to infinity. But unfortunately not suitable with the SonyA7R.
This is the first version of the lens and would be ideal because of its price, I paid just over £200. You can get the version 2 and version 3 of this lens and they would work better on the little Sonys but the price is much more, so your defeating the object of getting a super wide lens for you Sony on a cheap budget.
So, instead of the Voigtlander if your after a super wide lens that works 100% for your mirrorless full frame Sony and you want a reasonable price I would choose the Samyang14mm and the Samyang 12mm fish eye. Both great lenses that I’ve owned and produce sharp photos.
