Hah, ok, I was wrong, turns out car temps can rise more than I thought, found some model where if 50c outside, the car can be 80 in a few hours...but ok, talking about other bad solutions then we have the winner; SD cards! Storage and operating temps go up to 85c! =)

(Amazing how they must design and test car electronics to handle everything from -40 or so (in other countries) to that over many years..!)

(But seriously, talking/debating is fun, but when factoring in time spent, sleep lost, hassle experienced, swapping/moving/backing up disks/cards etc...do the cloud thing, I'd say it will be worth it almost no matter which cloud solution you go for)

I would still choose cloud for the benefits already mentioned, but regarding temps, modern SSDs are rated for a operating temperature of 0-70c, and I doubt you get that high even down there =). (Also thats operating temp, storage temps might go higher, or not..) Regarding the shifts, I don't know, but I mean those would be over several hours? Whereas the shifts in a computer case can be i a minute or two so my guess would be it can handle it, but again, cloud would probably be better in many ways =)

Agree, many quality SSDs are rated in number of "DWPD" - disk writes per day for the guarantee period of say five years, meaning you can write the entire disk space each day for several years without worrying, which is nowhere near the case for photo backups...but as for the price if using SSDs for backup that's another matter =)

I see, I probably misunderstood your usecase then; but I agree that hosting the server at home isn't a great idea regardless so I agree about that!

About the initial upload, it might be overkill (and now I'm starting to sound like a backblaze fanboy, but I'm not, just a satisfied user that likes their quarterly disk failure reports =) ), but if you want to upload all your data over that connection you will have to bite the bullet and transfer the data somehow no matter which service provider you choose, and although expensive, if there's no other way to do it, they do offer a "fireball" solution where they rent you a 70TB box, shipped to you by "mail", and then you transfer you data to it at home and send it back, and they put in in their cloud and you can start doing incremental updates from there. But it's $550 for 30 days for that box so might be cheaper to move your server/computer to a friend or relative overnight somewhere where better connections without caps are available for the initial upload if that's a problem (but unless there is something in your contract about max upload I don't think there should be an issue even if you use all of it 24/7). Either way good luck in your search!

You can always crop and the 100mm is plenty sharp, but to get a "large" sharp shot of a couple of torsos and some sweat/teeth flying =), I think it may be a bit on the borderline with a 100 on a K5 16mpix even with cropping.

But I'm no expert on these shots, haven't done a lot of similar so better wait for someone more knowledgeable =). (For example my guess would be that the 100 wide open+crop would give you similar if not better shots than the 18-200@200@6.3, but I've got no experience from that particular lens, and it was a couple of years since I had a K5 and 100mm (not the II), so I think others will have more valid thoughts).

But if the K5II is similar to the K5 in focusing, I'd say not to use AF but pre-focus manually and shoot when the action happens at the distance you've focused on, othewise the af will delay your shots, miss some in time and some in focus. (And if the lighting allows you to use a F-stop/iso/shutterspeed combination that allows for a depth of field that captures a lot of the ring, all the better). Also if you have a memory card that allows it it's better to do some "pray and spray" for maximum number of keepers rather than being selective about framing etc. and getting a good percentage but low total overall.

While talking about manual focusing and lba =), if I may give one suggestion in that direction it could be the Pentax-M 200 F4. I think it can be had for $50 if lucky or up to twice that if in a hurry (without having checked, I might be somewhat off), but while manual it's ok sharp even wide open, especially on aps-c (I think the PF score is perhaps a bit low just because f4), and at f4 not superfast but more total resolving power vs distance/light than you have now I think.

Now wait and let someone that actually knows something give some advice =)

Edit: Seems the M 200mm F4 can be had for as low as $25 in the states if lucky, or less than 50 at least, so might be an option!

I never thought about speed, but just tried a run and I get 10-15 mbyte/s upload (~100 mbit), and I'm in Sweden while their servers are in the US as I understand it, but I think that may be my ISP upload limit so perhaps not a backblaze limit. But since that just uses some disk and network and no cpu and could basically be "always on" if you wanted to, even while editing photos without interfering much with performance since it doesn't use a lot CPU, GPU or RAM, so I don't think the upload speed should be an issue anyhow?

Regarding what to backup, as I mentioned, with the commandline tool and b2 storage (and not the "whole computer backup"-plan) you can easily specify what to backup and not to further limit whats uploaded. The computer-backup has some build-in restrictions on temporary files, application files etc, so you can't restore a computer installation with OS and all from it, just the data. In my case I just run

b2 sync --dryRun --compareThreshold 1 [path to my photo storage]

to sync see what will be uploaded from the photo raw drive, no actual transfer, and then

b2 sync --compareThreshold 1 [path to my photo storage]

to actually to the sync, but there are many options and details that allow for customization and you can run this on a schedule in windows or linux at least (probably in macos too). The comparethreshold-part is just because linux uses different precision of file datetimes compared to windows, and I use both, so maybe not necessary in your case.

As for security as someone mentioned, you can either encrypt it yourself before uploading, or they also have support for you to provide/configure your own encryption key locally so that Backblaze themselves can't decrypt your data even if CIA tried to force them =).

Edit: About uploads/plan; since you define what to upload or not with b2, and it's all "syncing" and not uploading all the data every time, I don't see how you can get a full cloud backup using any less data no matter what solution you use? (Sure the whole-computer-plan from backblaze will backup more, but no need to use that). Or what you could do if willing to spend the time and effort you could try to compress raws using 7zip or so before uploading, but that won't gain much when dealing with raw files and also not worth it I think, since youre not doing that today? (nobody is probably..). But all in all, even if you just get 0.5 MB/s, leaving the computer on overnight would solve that, so the upload speed shouldn't be an issue regardless of plan I think. (if there's a cap on total upload in the plabn there might be issues, but that would go for any cloud backup regardless, and be more related to what you upload rather than to which cloud...)

I'm sure you can get some good shots, the 50mm is fast as you say for the big picture and will work, but if there's anything I'd "complain" about its about missing longer focal lengths for close-ups. 200 might be ok but you'll have less light and IQ with that one, so if you can borrow or rent ( or buy, LBA is great! =) ) a faster and more high-IQ lens for that area I think you'll get a few more superb shots!

I also use Backblaze, and I agree that the backup-computer-variant is probably easier, but if you're willing to spend a few minutes, then their b2 cloud storage option is even cheaper (probably, depending on how much data). I pay about $2 per month for about 400 gb of raw file storage cloud backup that I can reach from any browser! So 1tb I guess would be something like $5 per month or 60 per year.

They have various interfaces for different NAS:es etc. that they integrate with, but I don't use that but simply use their b2-command-line tool and run a one-line-command once in a while to backup my entire photo drive to a "bucket" i set up (it syncs changes, not all 400gb each time). But it could probably be automated so it's run every time something changes on that disk if you want to.

Disable green button for back-button focus?

Hi, I just tried to use back button focus in my K1, and just being my first time I can't say I felt the improvement yet since old habits keep getting in the way, but one problem i discovered is that I now hold my thumb, to be ready to hit the af button fast, in a way that easily touches the green button when just carrying the camera in the handstrap. This of course leads to many wrongly exposed pics unless chimping a lot to detect the error...

So my question is; is there a way to disable or re-configure the green button? I shoot in manual mode 100% and I've more or less never used it so I won't miss it.

I guess in time I will get used to it and not touch the green button by mistake, but to make the transition less painful, is there a way to configure the camera so this won't be aproblem?

(Tried to search but mostly found questions about half-press disabling, and that one I found..)

Trying to decide what equipment to take to Europe

Something not mentioned yet is that since you'll be going to a lot of cities too, here in Europe the most interesting older parts have very narrow streets and everything is crammed into a small area, so looking at focal lengths you seem to have the upper bit covered ok, but if possible I'd get something wider than 18mm too (also great for landscapes in Norway etc).

(You wont be going to Venice, and perhaps that's an extreme example, but my 12-24 barely left my camera while there, and a lot of the pics were closer to 12 than 24...)

I'm trying to get a better understanding, and perhaps relieving "the stress" I feel with having lenses that I have no good (well what I think is "good" anyways) reason to use...and not saying they aren't good lenses, but for example, was it for the fun of trying something new, or why did you use the F 70-210 when you have the Tamron 70-200? (SP?) Weight/size? I can never get around to bring "my second best" lens for an occasion unless reasons like that I won't have time to change so must have a zoom instead of prime etc.....or is it just LBA? =)

I have also got a bunch of lenses from packages where I was interested in a certain other lens, but then cursed that my bid won (even if at a good price) and must go though to test it a bit, take pics of it, put an add etc. etc...so I can confidently sell it and i still have 5-6 manual fifty:s that I need to sell

I guess some of the arguments are about it being non-"Linuxy" in building everything together in one blob where dependencies and feature creep make it more insecure, less predictable, easy for bugs to slip in etc...but in truth I guess a lot of the situation comes from a, well, lets say alternative facts-kind of behavior/prioritization/responses from the "product management" when bugs or security issues have been found. (And the Linux community is used to dealing with Torvalds so that's saying a bit...but in a different way so and I guess I agree that it's better to make a big scene over minor issues like Torvalds sometimes did, rather than silencing more serious ones)

Maybe partially a joke (or not =)?), but I have to admit mine is perhaps "fast and just a bit furious"...many times I don't have time for "quality photography", so while I mix AF and manual focus and don't have a focus screen, I generally make sure that what I want is in or out of focus first, but then shoot wider if the lens/footzoom admits it and do the most of the "framing" in post to save time but also be a bit on the safe side in case I miss something or will want to have another framing later because of details in the shot I didn't notice when I took it. Yes, it means I crop and loose resolution, but I feel from the 36mp in the K1 and to the 4mp in a "high-quality-but-not-for-print"-output, there's a lot to take from. (I rarely print)

Colour and tone rendering - CCD Samsung GX-10 (Pentax K10D) vs CMOS Pentax K-3

I think it does. I guess we need to start requesting factory-calibrated sensors or calibration tools like for our screens!

Joking aside, or not, perhaps that could be a differentiator between brands if a "ISO standard" or something like that for sensor color accuracy (including the profile) existed and cameras or sensors could be rated according to how accurate they are..like say audio amplifiers that have snr, thd, imd noise metrics etc. Then there will always be, like in audio, proponents of more subjective characteristics so not all will agree that the most "accurate" sensor is the best, but that's another discussion...

But either way I'm at a stage where I don't have much time for "quality" photography but end up doing mostly "documentation" of family events/vacations etc, so I don't spend the time on the color work that I would perhaps want/need to be close to this being a top priority. In few years perhaps =). Instead just reading and commenting about it and dreaming that one day I will make my own color profile...=)

Lots of insightful answers, and you said you preferred the CCD output, but you avoided my "$1000" question =), since you have seen the chart with your own eyes; which output do you think resemble the real thing? Is the CCD closer to the truth, or does it over-saturate the colors compared to what you see?

Thanks!

Great experiment and interesting result! (I had only heard the discussion about that but never looked more at it)

To my understanding, wouldn't the color matrix "just" be the cameras own way to tell the software using it how the camera/maker thinks the raw values "should" be mapped (to a certain color space) to arrive at the intended (by the maker) colors? (So each raw converter could have it's own default profile for each camera model affecting this result?)

If so I guess the not-possible-to-answer-objectively-yet-is-the-$1000-question is =) : Which one looks more (on your screen) like what you see (with your eyes)?(parentheses included for emphasizing that those will be variables that may differ and alter the result others do the same experiment...)

And if using the default profiles in DT, is the difference as pronounced, or have they "equalized" the extremes?

Edit: And if they are not as different with default profiles, are they "in the middle" or do the DT profiles "prefer" one of the looks over the other?

"Equivalence" between formats and lenses...

It may be creating a smaller problem, but solving a far larger one: I believe stating focal length on lenses has created far more debate/misunderstandings than FOV+(intended)sensor size would have. 99% of users don't mix and match but use the lenses on the "correct" sensor sizes (DA on apsc etc). Now, for pentax users that is a bit more due to older K-mount lenses on APSC-cameras, but for us that frequently do this or override DA lens format on K1 etc, we can easily "convert" FOV or focal length between formats and understand the consequences, while most users don't get all the details of the equivalence discussion and would get a better understanding of the lens properties by FOV for expected sensor size vs focal length.

We seem to disagree, and that's fine, I won't have it my way ever any way =)

Semantics, I thought it was clear I meant sensor size, we can crop to reduce fov, but not increase it, I shoudn't have used the word format, but I mean sensor size. My point from the start included sensor size, but I said "format suffix", my mistake . But the FOV marking of lenses wont happen so a moot discussion I guess.

Well of course, but the crop I can choose (in settings or pp), the format not as much... getting a larger sensor in firmware update would be another thing =)...

(so jokes aside if I express myself badly, no I don't think any crop should be considered on that FOV marking =) )

Yes, that is why I wrote "with a format suffix", most lenses are after all made for a specific format even if they are sometimes adapted to others. But I agree, what you say was the point I want to make, the format matters for the FOV, that's why saying 3-18mm on a compact isn't helpful at all...it has to say something about the sensor size or format too in order for a user to get a feeling for the FOV of those "3-18mm", because the FOV is what were after, not that this piece of glass focuses light X mm behind it...

Now, focal length + format OR FOV + format would both give enough "data" about the lens to know what to expect, but I argue that people mostly use the focal length in order to understand the FOV when using it, and not to consider the physics of the lens, so I think discussing and printing the FOV on the lens would help (and prevent some misunderstandings) in favor of having the focal length, but if I could choose I'd prefer both on there.

(Or in truth, since I'm lazy and already used to FF/APS-C/m43 focal length I wouldn't want that changed really =) ...but if getting into a new format or learning photography all over again, I think that (FOV+format or sensor size) would be a better property to print on lenses and discuss rather than focal length without format, as today)

I agree that the lenses shouldn't have "pseudo-focal-lengths" like that printed on them that vary according to the format they are intended for, that would just confuse things, but perhaps an additional FOV printed on them (with a format suffix) would help I think. Sure I have no problem with FF/apcs-c/m43, but when compacts or phones with different hard-to-find-sensor-sizes say that the lens is a 3-18mm lens...that doesn't really help me at all to get a feel for what to expect.

(But I guess this post isn't about equivalence but more about what's printed on the lens....)
