Firstly, I want some that will allow my Sigma 150-500 to go "farther" (i.e., 700mm-1000mm) if at all possible, and I'd also like something that would allow my Zeiss 35mm to operate as a macro. I don't know anything about these, but I just want more flexibility with my existing lenses. Note that apart from the resolution concerns making a teleconverter pointleiss, the sigma also has an open f/stop of 6.3 (reported to the camera as 5.6 in software so autofocus works), which will turn into f/9 (reported as f8, probably?), making this lens really really dark so you won't reasonably handhold it anymore, IS or no. As extension tubes, get the Kenko ones for great quality at a price that's still kinda high but not completely ridiculous like the canon original extension tubes. On a 35mm lens, your working distance will be sort of low though, there's a reason most macros are 100mm-ish and very few are below 50mm.

While walking by some tide pools, my shorty forty took a tumble from my pocket and became briefly, but fully, submerged in salt water. I have it in a bag of rice right now and will leave it there for at least 48 hours, but how likely is it that this thing is hosed?

Did you rinse it out in distilled water before you went and stuck it in the rice to dry? If not, I wouldn't risk it now - there's probably mineral deposit already on electrical contact points that has started to dry on, and you could short something supplying power to the lens.

I rinsed it off in purified water as quickly as I could and now it's in a bag of rice. I'm prepared for the possibility that it's wrecked, but I'm not taking it out of that bag for at least a few days.

Yeah, it may still be wrecked, but at least if you rinsed it in distilled (not sure if that's what you mean by purified) it's less likely to ruin your camera also. It has to be distilled water though - anything else will have mineral content in it.

Yeah, regular bottled water for drinking and especially tap & even brita-filtered water have minerals in them to varying degrees - the shorty forty is a shame to lose but it ain't exactly an expensive lens and its probably better to be safe than sorry. Comedy option, once it's dry & clean go to a pawn shop and ask to try out the lens on a camera they have 'to see if it's compatible' before using it on your own. (Don't actually do this unless you're prepared to pay for what you break.)

So the 40D I bought from a goon (thanks by the way, great camera,) is starting to have issues, (The tokina lens broke and I got it fixed), and I might as well upgrade. So because full frame would mean tossing out half of my lenses, I'm looking for a modern replacement for my 40D, What's the current replacement for the 40D looking like.

If Canon is coming out with a new 1DX this year, when would they most likely announce it? I don't really know when the big shows happen but I think Nikon just did some big reveal so I'm curious if Canon is going to as well soon.

Canon Rumors says the 1DX II is shipping in April, so expect an announcement in Feb or March. http://www.canonrumors.com/canon-eos-1d-x-mark-ii-coming-in-april-2016-cr3/ People like to scoff at rumor sites, but he doesn't mark things as [CR3] lightly. He's pretty much always right when he does.

I sold off some useless crap, and a second body I never use. Funds will be going to an ultra wide zoom. I can afford the following, anyone care to recommend, I couldn't find info on them all at DxO, or DPReview? Used Tamron 15-30 Di VC (heaviest, largest) New Tokina 16-28 (cheapest) Used Canon 17-35mm f2.8 L (oldest) Used Canon 16-35 2.8 L Thanks e. Wrong Tokina lens.

"[ts posted:xenophobe" post="454910694"] I was gonna say the Canon 16-35, but then I realized that you might not be buying for a full frame? Pretty sure that Tokina is for crop bodies. In which case, 16/17 mm doesn't get you a ton more on the wide end than a kit lens...

"[ts posted:xenophobe" post="454912587"] Have you considered going completely goofy and getting a Sigma 12-24?  If it were me, and I could afford L glass, I'd buy L glass--the 16-35. 1mm is a bigger difference than you'd think at the wide end, and it's apparently an improvement over the 17-35.

According to our friends at dxomark the Canon EF 16-35mm f/4L IS USM gets a better sharpness score than the Canon EF 16-35mm f/2.8L II USM. In their graph it's a bit soft at f2.8 but they're probably the same at f4... Or just get a canon 11-24

Depends how much you care about peeping level corner sharpness - the IS is a nice bonus too.

"[ts posted:xenophobe" post="454929737"] Well, you'd have to try shooting at f4 in your usual conditions with another lens and see if you can deal with it or not. @2.8 you will still have a good amount of DOF for like a posed group shot, but maybe not so much for a dispersed crowd shot (depending on your output size of course, and what you actually want covered in there) Lot of variables to take into consideration for your needs

That's not really a fair thing to say when you consider also at least RED (including the Dragon sensor), Panasonic, AJA and Blackmagic have flunked out usable DR tests made by Cinema5D or Geoff Boyle in very similar fashion. Some being really jarring like Dragon sensor (claimed 16+ stops) rating at 10 stops under tungsten light (CML test) and AJA Cion rating 8 stops (claimed 12 stops) at Cinema5D. Pretty much every manufacturer outside of Arri exaggerates their DR claims.

I should have specified - I meant what independents testing sensor DR (Cinema5d, IMATEST, DXO, Bill Claff, etc) are using as an acceptable noise threshold, rather than manufacturers. You are absolutely right that most of the video manufacturers are exaggerating in the same way Canon is. The industry was a poor choice of terms for me to use

Keep in mind that's sony S-LOG video being measured, not the RAW performance you get from stills. (Although the same thing for Canon - C-LOG vs RAW) Canon hasn't trumpeted that the C3002 sensor had an on chip ADC, or independent gain on pixels (a la ML dual ISO) , and you'd think if Canon finally made one of those huge jumps they would shout about it. Plus the A7 cameras they were measuring in that test are hampered by only having 8 bit video output vs the 10 bit output of the C3002 & Alexa. The sony FS7 was also tested, is 10 bit and still didn't do that much better though (3/4 of a stop or something like that I think)
