what have I done?

About three weeks after letting the GX85/7.ii go to a better place, I ordered a Xiaomi (Xiaoyi?) M1:

Why would I do that?

Well for one thing the finances that I've been expecting for a month or two began to move from rumour to fact. While I wish that had happened a week or two back, one takes what one can.

Well ok then -
But why the YI M1?

Well, settle in for a bit..

Once funds were looking likely I resumed my never-ending circle at

1. what do I have now? A Pentax k∙50 and a GX1. Both decent, neither excellent.
2. what do I (claim to) need? A better Pentax would be excellent and take native advantage of my many K-mount lenses. A better µ43 camera could use them also, as well as my tiny native µ43 lenses.
3. what is Better? Ah, the hard bit. 

Better for Pentax would be a K-3 variant for more resolution and battery life, or the K-1 for ultimate top-notch monster images (and gear size..). Better for µ43 would be a G85 for weather seals, or a GX8 for the much-liked 20Mpix sensor. In either case we're talking $500 to $1100 to step up in a big way. I could settle for others like the K-5, another GX85 or an EM1v1 with some nice improvements from today's team. Really though the K50 sensor score at DxO is better than any m43 option and so similar to the K-3 that it's not a true step at all..

Decisions decisions.

And so finally to step 4: what is Out There?

Hmm, a K-5 for about $500, a bit more for a K-3ii with pixel-shift abilities? About $1099 for a used K-1? On the other hand, a G85 (but no 12-60 sealed lens) for just under $500? GX85 bodies for ..$100 more than I paid a month ago is hard to swallow, but it happens. GX7 bodies for just over $250, perhaps?

Or a YI M1 used for $210 with the 12-40 lens included?

Let's review my reviews. I had looked at the YI a while back, and it had several nice features and many question marks. Its battery life is higher than many and recharges live on a microUSB cable like the GX85 (and unlike most others). It has the well-liked 20Mpx sensor (read about TOP's love for this sensor - and also how Mike's rating system works!) and its firmware updates have moved the M1 up in reviewers' eyes from atrocious to almost impressive. It has 4k video for what that could be worth in my future, and a 4:3 "2k" video that could prove interesting at times today. It uses DNG default for raw images, so no software hassles.

The M1 has a very simple interface that could entice my wife more than most other setups, and wifi/bluetooth options for off-camera imaging. More importantly, reviewers state that Lumix OIS lenses are stabilized on the M1 - that's a big deal to me.

Let's be honest though: the 30-day return policy was a great help in making this happen today. Just in case.

Hey look at me: I just saved $300 or more!

tough call

Rinse and repeat - I put the GX85 on the block yesterday. Just when I was getting the hang of it - well not really, it has a lot of features I did not get to play with!

However, several variants of bank loans failed to materialize after many promising chats. The optimism was infectious and I allowed myself to relax a bit - and it was again premature (see my last six years or more of camera ownership for many other examples).

I will go forward with K∙50 + GX1 plus many nice bargain lenses that I recently picked up. All other deals will be on hold for a while. The Sigma 60/2.8 is also up for sale given the DA70's arrival.

K50 plus zooms (Sigma 10-20, 18-55wr, q-ray 100-300, sigma 28-200) and primes 
(Vivitar 24/2.8, da40+70mm Limiteds, smcA50/1.7, smcM100/2.8 and 200/4).

GX1 plus 12-32, 14-42, 45-150 zooms, 14 and 60mm primes.. and pretty much all of the K gear above!

the crowd gathers.. and a new surprise

The DA70 arrived today, prompting this size comparison -

From left to right: Lumix 14-42.ii, Vivitar 24/2.8, Sigma 60/2.8 DN Art, Pentax DA70.2.4 Limited with hood, and Pentax DA40/2.8 Limited plus µ43 adapter with aperture control plus its mini recessed hood! Yes the DA40 is that small, and the 70mm barely larger without the hood. I just missed a bid on the DA21, another tiny prime.. another time, perhaps.

Update - While looking at DA21 prices on the GAS (Global Auction Site) I encountered a K-mount Sigma 10-20mm hyperwide for substantially less than any DA21 copies - and a very useful range with either kit. Definitely a bit bulky though. The DA21 would be relatively slow but the Vivitar fits better into the gap now. The oddball now is the 18-55, so it can be swapped somewhere for a DA50-200wr to cover above the 70mm. Looks like it's time to re-evaluate bodies .. again.

a simple question

A couple of days ago I nearly bought another camera. It had a feature or two I don't have that would be nice to have, and it was a very nice price. Who wouldn't do that, show of hands? Ah, you others are new here aren't you - read the subheader on my 'blog and you will understand a bit better.

Does it matter which camera it was? Could have been a GX8 or G85 for weather seals, maybe an EM1 v.1 for the same reason. Or maybe it was the sensor: GX8 and YI M1 have the notorious 20Mpx that gives people like theonlinephotographer 'classic' results in a digital body. And who's to say it was not in fact a K-1 v.1 with its ultimate features and compatibility with most of the lenses I own?

(Honestly it was more than one camera - but not that entire list.)

Sitting beside me here is a camera that's small, sealed, has lenses ranging from 24-800mme (though only one is sealed) and takes Pentax prime lenses. It takes great video and can pull still images out from it, and the sensor does very nice work. It's my..

Once again, does it matter? 

What does it do so poorly that I still seek relief? 

To put it another way -

OK the answer is my GX1, K-50 and GX85. No one of them does all that, which makes the G85 tempting.. but the sealed lens is on the K-50 so add a 12-60 to that expense. Wait that does not charge in camera like the gx85 and has a flip screen not the tip type? It's always something, and camera makers like it that way. I'm their ideal buyer - well except that I'm forced to stay with used items until my lottery ticket hits.

At times like this the K-1 looks really nice, with decent compatible lenses already in hand.

live and learn: GX1 and GX7.ii sensor test

As I have noted before, I am just awful at side-by-side tests. I usually keep a few variables varying, and make changes where I don't intend to. Nevertheless I'm trying again, with a simple goal in mind: seeing with my own eyes what a 16Mpix GX1 sensor can do compared to a GX85 (GX7.ii is my preferred name for it).

So here's my testing setup -

• bright lamp shining on aluminum foil, a few bright objects and a black desk and file holder
• ISO500, tungsten light WB
• Manual exposure at 1/30 second
• Pentax DA40/2.8 shot fairly wide open (no aperture ring to read from - but the setting did not change) and focused at similar points
• framing using "just above a paper clip, top of rocket pen on right edge" precesion
• RAW exposure, opened in Cyberlink's PhotoDirector 8 software, then
• captured with PrtScrn and
• pasted into my favorite tiny graphic processor, LView 1.D2!
• Only the exposure slider was used to adjust between captures

Note that I deem many many issues to not be relevant to this specific test, so I did not work on these!

• specific point of focus
• perfect shooting posture
• absolute center of image
• 'shutter shock' and IS are not factored in - SS should not be a factor at 1/30s but my quivering is another matter!

For sensor capabilities related to gathering light, a bit of blur or imperfect focus won't blow the results to pieces. If they do I am clearly in the wrong hobby (or more precisely: my critics are).

So what did I learn, I asked myself?

First off, base shots and raw settings 'as shot' imported into PhotoDirector 8.

Hmm the upper image "P104" (from Lumix folder P104) has better white balance with the tungsten preset. It's definitely an orange-gold rocket pen not a yellow-gold. The as-shot sliders are amazingly different, but I tried similar settings and the results were definitely worse - so for each camera the choice was a decent one.

I see more detail in the P104 yellow flower, but I believe the focus was about spot on for that shot and further back in the P116 image. Since the results were not precisely the same, no doubt I wobbled slightly in my chair while swapping the lens between two bodies. That's not the goal of this test so I'm fine ignoring the flower details here.

So down to about -2EV we go, to see how the foil and other bright items hold up..

Personally I'd say the upper image P104 has preferable blowout results than P116. Differences are pretty slight though. Looks like focus differs on the far-left paper as well. Thus far P104 is holding a slight edge to my eye.

Upward to -1.3EV now..

Nothing to see here, really. Dark areas behind the foil lack detail in equal measure and the yellow WB bias in P116 gets worse in more light. The foil is a bit more blown out in P116 as well.

EV+0.25 coming next:

Looks like a bit more detail in the darkness now on P116 (lower) image. The flowers are a bit more blown out but I'll gladly take the blame for non-rigorous testing procedures. Heck I didn't even crop the same on every one, how slovenly can I get??

We'll close out with EV+1, since that's as far as my interest held tonight..

Dark areas look great and foil looks awful, pretty much in equal measure.

 = = = = = = = = = = = = = = = = = = = = = = = = = = = =

The results are in! My reasonably rigorous test was really disappointing, in that I feel best about the results from P104 - but my humble GX1 (P116) is not a Godawful DR-crippled pathetic excuse for a 16-Mpx sensor. I might try re-shooting these just to nail focus.. but really neither camera does poorly anywhere in the tests so I probably will not do that.

And in all honesty: as I wrote this I thought P116 was from the newer camera (higher number better, right?) so any bias I felt was in fact doubly blinded! No doubt from the foil.
