Pentax K1 Questions : Live view softness (?) & Screen Loupe

I'm considering buying a K1 & have two questions for any K1 user, both concerning Live View:
Unfortunately I haven't seen one so I'm canvassing for opinions


1 DPReview reported that Live View is extremely soft on the K1 (their words:

Special K? Pentax K-1 Review: Digital Photography Review

I can't find any mention of this elsewhere. Has any user experienced this? This would be a major minus as it impacts manual focusing.


2 Has anyone used a screen loupe? I know the Zacuto Z Finder doesn't fit. I'm hoping this GGS Swivi will work:


GGS | Swivi S2 Foldable Viewfinder


Thanks

Are you referring to this paragraph...

It's also worth noting that the Live-view image preview is extremely soft, so manually focusing without Focus Peaking enabled can be a very tricky ordeal. Getting things pin-sharp is critical with the K-1's large 36MP sensor, and even more so when the Pixel Shift shooting modes are enabled.
You got me...perhaps the screen was smudged with cheek grease. If this was a user observation on this site, the conventional advice would be to enable focus peaking (a simple task using the info screen) or magnify live view for 1:1 pixel mapping at the rear LCD resolution.

They added the electronic shutter in the meantime. Now, when conditions allow and the lens is sharp, we get more details than needed.

The screen is no different to my K01 screen. When you switch focus peaking off you often get a sense of softness till your mind accustoms itself.

I think what they're possibly referring to is shutter induced vibrations, the solution is to use the new electronic shutter option. Also on some cameras it's a non issue, while on others it can be noticeable between about 1/90 and 1/180.

Used LV many times on the k1. Have no problem obtaining critical focus using only my eyes. As Steve pointed out you can use the 100% view for ultra critical focus.

Have not felt the need to use Focus peaking or Contrast detection Af when using LV

The quoted text is a little ambiguous. I took it to mean the actual live view display. Do you think they were referring to the digital DOF preview?

Either way, I have not seen the rear display quality as a common complaint on this site.

Definitely not, I'd say on the contrary the screen is quite good.

I don't have any issues with lv. I use it for all landscape or any other tripod shots, lv with es enabled for maximum precision. One thing I wish they had is better/more customizable peaking, current one is sometimes confusing, especially with uwa lenses since a lot of an image in the distance would be in focus, judging just how much in focus it is can be a bit of a pain with peaking.

dpreview are being a bit silly, as usual. And critical of Pentax just because.

LiveView is not any 'softer' on the K-1 than it is on any other camera I've used.

LiveView viewed via the rear-LCD display of most cameras is, after all, never a HD capable display. A ~1.2 million dot rear LCD like that found on most current cameras (including the K-1, D810, D750, Canon 5D4, and Sony A7R2), is usually a mere 3:2 640x480 RGBW VGA display. The rear LCD is certainly never the same 'resolution' as one would see with a full HD or UHD computer monitor, nor can it capture the same visible detail of an optical viewfinder, or even most EVF's.

Having said all that, LiveView in the K-1 gives a photographer access to many focus aids to easily overcome any limitations of the low-res rear display, from 16X magnification of the focus target, to focus peaking, to very fast and competent face detection.

Yes. As I said it's the only mention of this I've seen anywhere. Eventually I'll have to find one & look for myself.

I don't really understand this. Can you elaborate?

Useful to know re the loupe. Hopefully a Swivi S3 will fit too.

When in LV you can opt to use ES...Electronic Shutter. The start of the exposure is now no longer controled by the first curtain, but by electrically telling the sensor to start recording the exposure. The exposure is finished by the second curtain closing in the normal way. This means that you cannot get shutter-shock induced blur in your picture (which can occur, depending on lens, in the 1/30-1/180 range) when using a tripod. As Live View obviously also captures with the mirror in the up position, ES is the best way to ensure a perfect photo when using a tripod.
