Is it time to ditch the SD card concept?
Posted By narual

Because those things happen with the frequency of water damage to electronics? SD cards are really hard to screw up. SSDs are a different beast. Especially once someone gets the bright idea of encrypting the data to lock it to a single device.

At any rate, this entire concept is a solution for a problem that doesnít exist. In a drone, every excess gram reduces flight time, and an ssd chip soldered permanently to the board removes the weight of the entire (micro)SD mechanism as well as any waste weight from the casing of the card. It also offers up selling options to the manufacturer, like a Mac, where Apple can sell increased storage and memory at several times the going rate because it cannot be upgraded later.

A camera doesnít need to budget every last gram against battery life, and it certainly doesnít need fixed storage like the garbage devices that some of the first consumer grade digicams were.

I seem to remember lensign focustune working for this too, but I could be mistaken.
The lens align creator, Michael tapes, has cancer and let his main site and the lens align site shut down, but you can still buy lensalign with focustune at bh/adorama/Amazon and the support site is still live.

Even if it didnít do the adjustments directly, I remember it doing an amazing job of helping me fine tune my focus.

So far as I can tell those two da* lenses have identical rendering. I like the 50-135 better since itís easier to carry and use handheld. Iíve had it repaired once (dropped it from 4 feet at just the wrong angle, knocked an internal but loose and messed up focusing), and the second time it broke (literally snapped, the mount stayed in the camera and the rest came off, with all the pins and springs popped out, some screws broken, after it flew from my passenger seat to the floor when I slammed on the brakes to avoid an accident), I bought another one because the used price was about the same as the repair.

The only 3 lenses I try to always carry with my camera are the 50-135, the 31 ltd, and the smc 15mm ltd. I love my bokina and 50mm/1.2 porst, too, but theyíre a bit too heavy and situational for always having handy. :)

Now, could I find any photos that gave a decent 1:1 comparison to show why I feel like they render the same? Not really, but here are a few from both since this is a thread for photos anyway. :)

K-3 isnít recognizing 77ltd lens
Posted By narual
Replies: 3
Views: 702
I donít use the 77 as much as the 31, and Iíve barely used my camera since messing up my shoulder last fall,

Popped on the 77 this morning to shoot a very large group photo from across an intersection ... and it asked me for focal length, showed Fó, and no autofocus.

Took it off, nothing looked wrong with the mount. Put the 31 back in, detected it no problem. 77 again, no luck.

Aperture ring is on A, nothing weird with it. The lens is pretty pristine. Itís lived in an optek gasketed mount cap since day 1, in a padded neoprene pouch. Never dropped, barely used.

Anyone have suggestions?

Thanks!!!

Under $100 you're looking at something universal, not made to fit the specific camera. Finding one intended for use with a grip may be a bit of a pain, not sure.

You can get this one intended for a generic dslr body without grip from B&H for $20. Desmond Desmond DAL-1 QR L Plate DAL-1 B&H Photo Video

Left lenses in basement for two day-what should I do

Unless you're replacing or drying them out in an oven regularly, you have a few packs of completely used up desiccant in there.

They don't really last that long when they're not in completely sealed environments, and anything you get inside something else (say, the ever popular tiny packets from inside shoe boxes) is probably already completely used up. When you order them fresh, they come in sealed containers.

If you want to be confident you're actually protecting your stuff, get something like this: 10 Gram Indicating Silica Gel Aluminum Canister - SilicaGelPackets.com - it changes color when it's no longer absorbing moisture, then you know to throw it in an oven (for 2 hours at 280 degrees F, it even has the instruction on the tin) to reactivate it.

Fungus will happily grow in the light and it doesn't really care much about temperature. It just doesn't like UV light and extreme heat. Humidity is the real killer.

In some cases, for manual lenses, at least, you may be able to do it yourself by adjusting the set screw on the focusing ring.

As an example, there's info on doing so with the samyang 8mm fisheye in this post:

I just bought a k-01 on eBay and the seller didn’t mention the missing dial though it was missing in the pictures if I’d looked more carefully. Any chance this ever got off the ground? I don’t want to pay 40% of what I paid for the camera for a disk and the only other option is translucent white for some dumbass reason.

One thing to note is the HD lenses have curved aperture blades where the SMC lenses have straight ones,

While this is generally a good thing for bokeh, it ruins the amazing stopped down star burst effect the SMC 15mm had with lights. The straight blades give you a sharp, clear, straight ray, the curved blades spread it out and make it less distinct. In thumbnails it's not an obvious difference, but at printable sizes, it's clear.

I have something like that, but this isnít exactly a situation where it would have been helpful, because I wouldnít have been using it anyway.

This stupid business trip (Iíve been in rural Minnesota for a month and because of the Canadian wildfires I havenít even gotten any decent astrophotography out of it) will finally be over Friday and Iíll be back in a semblance of civilization, so I can deal with repair quotes and so on then.

I have insurance, of course, but the deductible is probably more than a used lens. I’ll have to ask my agent. It’s under my business policy and I have no idea what the deductible is for my electronics inland marine coverage

Maybe if I include my 16-50 that’s become effectively a 16-35 after my wife dropped it on the floor of the car (never bothered fixing it because I don’t really like it that much and only use it when I need a wide angle in rain/mist) it’ll end up being worth a claim, but I doubt it.

Although I think the real underlying damage waswhen I had to slam on the brakes a few days ago to avoid a head-on collision and the camera was on the passenger seat, it actually broke when I forgot it was on the hotel desk chair and tipped said chair over to retrieve a sock that was beneath it... crap.

Snapped like a twig and Iím not sure if I found all the pins.

While it looks like a simple fix (one broken piece of plastic the mount screws into), I have no idea how much itíll cost.

Has anyone had this done and how much it cost?

Iíve had my 60-250 repaired but that was a more serious problem (dropped to hard floor from 5 feet up, no camera attached, internal elements broke loose) so I canít inagine itís a good comparison.

This is my favorite lens, and the one that came with my first Pentax camera :(

---------- Post added 08-18-18 at 10:33 AM ----------

Update: itís worse than I thought. Zoom ring is stiff and when I got it to turn a thin piece of rubber began to extrude itself from the area of the green ring and thereís a definite mismatch in spacing - the side wit the broken plastic mount piece gaps open so the green ring is loose. :(

You should really sell them together. The extender isn’t going to be as great with another lens and finding the matching extender for this particular make of the lens (the one that has auto aperture support) would be a pain if someone wanted it later.

I’m tempted, but I already have a bokina with the 1:1 adapter, it just isn’t one with an A setting.

mitakon 85mm f/1.2 vs a combo of porst 50mm f/1.2, samyang 85mm f/1.4& 8mm f/3.5

FYI, cyberjunkie, OP, and anyone else who owns or is considering a porst 55/1.2, yes, it's sort of milky/dreamy wide open... until you put a hood on it (one intended for 85mm lenses if you're on crop sensor).

And they're not kidding about the depth of field, and an 85mm/1.2 would be even narrower. Personally switching to a matte ee-s focusing screen helped but not enough - having focus peaking in live view makes it much easier.

Attached: all handheld in ambient light, with hood for sure on the foliage, the woman and I forget on the man but I think not; no hood for sure on the kid (that was the week I got the lens. I think that was actually like f/2 not 1.2 but you can still see the sort of dreamy/milky quality). Foliage shot is to show the narrow dof more obviously.

side note: that 8mm is not full frame, and get the rokinon "HD" version with the removable hood and better coatings, especially if you want to use it FF. It'll still cover a good bit of the screen. Lots of people on other FF systems were filing the built-in hood off of the samyang til the rokinon with the removable hood came out. :)

Good point. Without the removable hood you won't get a circular image even if you had a reducer. I've used mine on my ZX-L and the hood gets in the way til I take it off.

You could try the wikipedia article instead, if the tone gets in the way of your comprehension of the facts.

Normal temperature coffee does not cause third degree burns and require skin grafts. It might hurt like hell and have some redness, but it doesn't require hospitalization.

The jury considered her 20% at fault for the reasons you stated, but 80% of the fault was McDonalds.

People need to stop referencing that like it was a BS case of money grubbing. It was a matter of negligence on the part of McDonalds keeping their coffee at a dangerously high temperature despite over 700 injuries reported over several years (and serving them in flimsy cups). Normal coffee serving temperatures do not cause third degree burns requiring 8 days of hospitalization and skin grafts followed by 2 years of treatment, which is what the 79 year old plaintiff went through, and her suit was to cover her medical expenses and $5000 in lost wages for her daughter who had to take 3 weeks off of work to care for her. McDonalds offered her $800. She retained an attorney, who upped the suit to cover his costs in researching the case, mcdonalds refused to settle and the case went to trial. The jury decided the lady was 20% at fault to McDonalds 80%, awarded her 80% of the ~$200k compensation the lawyer had requested, and then tacked on a punitive damage amount in the millions (a couple days of coffee sales for mcd), but the judge dropped that down to 3x the compensation amount, and mcdonalds got that amount reduced later.

The plaintiff died in 2004, 10 years after the incident. She ended up using the money to cover the long-term care she ended up needing from the injury and recovery process.

I didn't know you could buy that separately... thought it only came with the 025/025x travel tripods.

I have the K20x bullhead, and it's absolute overkill for even a K3 with battery grip and 60-250 lens (fits great on the sirui 1205x tripod, though I suspect the C10 would let me close the legs completely and fit better in the travel case)
