D600 with canon mount?

WTF?

I agree, you need to compare apples to apples when it comes to codecs(inter to inter, intra to intra). Intra is almost always worse, and only shines under some very special circumstances, because you are restricting compression across frames.

I agree that the 5dmkiii isn't true 1080, but let's not pretend that the fs700, or the d800 are either. Recording true 1080, in 24bit color, approaches something like 1.2 Gbps. Even with good compression, you can't record at a 50to1 ratio and expect to resurrect true 1080 detail.

Honestly, from what I've seen, I don't see a huge improvement in detail in the fs700 over the 100. That being said, the fs100 seems to be the consensus "best bang for your buck" video solution in that price range. Personally, I'm still waiting for the affordable super-35 sensor cam that actually does something close to true 1080p. The most promising thing I've seen in development is the Kineraw.

the D800 does not capture full HD either, and I've used one long enough to know that for sure. It looks a little better and sharpens better than the 5DmkIII specially sing the uncompresssed 4:2:2 out and recording to pro-rest at over 200mbps. but ultimately, still looks terrible compared to a resized still image. Footage from the fs700 looks more like a set of stills and it is about as close to 1080p as the Cinema canon line is. but yeah, I think it may not be trully 1080p either. just very close.

My hope is that 2K and 4K video will allow us to do the downsampling to 1080p in our workstations to see if we can finally get better 1080P footage. This is the reason I'm keepin an eye on the FS700's alleged update that will alow it to shoot 4K. Even 2K scaled down would be leaps and bounds ahead of any dslr ouput.

There is a formula out there for how long of an exposure you can get away with for a given focal length without star trails being an issue. The shorter the focal length the longer you can go, but I can't seem to put a finger on the equation right now. I'm usually taking photos of the space station and I go 30seconds at f2.8 iso 800 16mm with no sign of star trails. Sometimes 60seconds, but that's just if i remember to bring my kitchen timer(it'll go to 60seconds or pretty much anything else while my camera only offers 30seconds) But that's not really getting it done with stars. Sure I have stars, but nothing like i'm going to be aiming for soon.

the sound clips sound louder than the actual shutters i just used an iphone and had it the same distance from each camera for each shot and yeah the 5D3 is nice and quiet

Anyway, the point is dont limit your capability just because you expect to have stingy customers.

I see your point, but my point still is that I expect to be broke in no time if I don't have my market in mind... I can still go for gold-plated lenses and life size prints once I'm in business and can afford the high-mp 5d mk4 when it's released in about two years.

Thanx or sharing the link. Can't wait to get mines

Get a 600D, its a time tested and proven entry level camera.

Tayvin · Jun 20, 2012

It's my favorite Canon lens. I'd buy used/refurb from a place that accepts returns. Even though it's a great lens you can still get a dud. Check B&H refurbs.

Jun 20, 2012

Did you use the touchscreen with a longer lens? I had a sony hdv/dvcam A1 which had touch screen and even with the slightest contact the camera wobbled at telephoto.

I wish Canon would introduce lanc control off camera, maybe the stm lenses are a move towards that?

Did you use the quality scale setting? Interested to see if you can attain a higher bitrate than with T3i.

Marsu42 · Jun 20, 2012

Thanks everyone for your input, so I've settled for a 5d2 for the time being running magic lantern now and being half the price of the 5d3. If you like, please help me to find the right 24-70 lens in this thread:

MJPEG is very good at high bitrates, it is at low bitrates that the newer codecs pull clearly ahead

I doubt Magic Lantern will go so deep into the image processing: with previous cameras, ML has been great at adding features, improving usability, providing monitoring tools, etc, but it has never been able to improve the image processing. ML mostly lives in the ARM side of the digic processor.

So, if the new encoder has a couple of parameters that they can change to get a better image, it will be a great win. But if that happens, it will probably be still IPB or All-I, not a new codec.

agreed. ML has its limits. It is more of a tweaker than a re-write. people also forget there are bus speeds, data path widths, read-out patterns and processing baked on chips which aren't firmware modifiable and are the real limits on top of the complexity of dealing with something as custom made for hardware as camera firmware. These are not general purpose PC's with OTS hardware. ML simply won't get 4K out of that camera the way canon could if they had set out to do that. If it was as easy to improve the quality as setting some parameters in some functions, canon may have just done it themselves. Not to say there isn't room for improvement and maybe higher bit rates but a higher bit rate is only going to help reduce codec panic in motion and not really improve quality since garbage in is garbage out.

I think the best thing for the ML guys to do is try to go for uncompressed clean HDMI. In that way you pick whatever codec you want and whatever bit rate it pleases you. The video won't be any crisper, but at least it will let you bypass the internal codec's mess.

But comparing the MTF of the pancake, 50/1.8 and 50/1.4, the pancake looks to be clearly winning.
Whether that's because of a rushed and/or lower-quality design of the 50s, or because it's easier to design slower lenses, or just 20 years-newer coatings or what, i don't know.

To be fairer we should compare the Pancake to the 50/2.5 Macro, anyone got the MTFs of that?

To be fairer, we should compare the Shorty 40 MTF to contemporaray 50's ... Nikon AF-S 50/1.4 and Sigma 50/1.4

all my modern EF lenses work on my film EOS Elan 7e thats pretty old

As far as I know - the new Samyang 24mm 1.4 for canon is NOT a TS lens.

You are right. But the rumors (coming from Samyang themself) says that there next lens to be announced this year (probably during Photokina) is going to be a TS lens.
As far as I know no focal length as been announced yet, even if some people here are talking about 24mm. That would be great and sounds very logical, but let's wait a few more months until the official announcement and especially until the first reviews.

Often, wide-wide-wide = boring-boring-boring. You stand in a spot with a great, wide vista, and you look around and are inspired. You take a shot with an ultrawide lens to try and capture that vista, and the resulting shot utterly fails to capture your feeling as you viewed the scene, and instead looks flat and uninteresting.

Why? As tntwit stated, an ultrawide AoV renders even moderately distant subjects tiny and apparently more distant. For an ultrawide shot to have visual impact, you almost always need an interesting foreground element - and with a UWA lens, 'foreground' means within a few feet of the lens. Also, that subject needs to be something that works with the perspective distortion inherent in that situation (usually not a person, as most people don't find exaggeration of their nose/belly/hips to be very flattering).

There's a good reason the shot you complemented was taken at a short tele focal length. Not trying to dissuade you from a UWA lens, just saying composing a successful shot with such a lens takes thought and practice - and might be difficult when the most common foreground element you'll run across is a guard rail.

+1. But a UWA lens would be a good choice for the Hurricane Deck/Cave of the Winds.

the advantage of the black card technique is you dont have another layer of glass involved to interfere optically
this technique can also be used with fireworks displays in bulb mode to get multiple bursts in 1 shot

its pretty clever and simple

First off, I'm starting to learn that with many of these PDFs accessed through a web browser, you have to download them by using the floppy disk icon in the toolbar across the bottom; they don't download properly from the menus or from a right click.

But, much more important, does anyone know how much of this manual applies to the 5D Mark III? Certainly much of it, but all? Canon put out what seems to have been a previous version of this document - which is now titled "updated" - which applied to both cameras, but do any of the updates only apply to the 1DX?

At 400mm, there is really nothing out there that can touch the 100-400mmL or the 400mm f/5.6L in the under $2,000 range.

I have owned the 100-400, 400 5.6, 300mmL, and a host of others. I ended up keeping the 100-400L as being very good, and easy to carry in a bag because its short when telescoped in. It also has good resale value, perhaps better than the other two.

I bought a D800 recently and am selling it. There is no good low cost telephoto solution that comes close to my 100-400mmL. The best of a bad lot may be the Bigma 50-500 OS, but I've seen few objective tests. The NON OS version was not all that good.

Click to expand...

you didnt try the siggy 120-300 on the D800? I think that would be a pretty kick arse combo

As I said, "At 400mm, there is really nothing out there that can touch the 100-400mmL or the 400mm f/5.6L in the under $2,000 range."

The Sigma 120-300 at $3200 is neither 400mm nor is it under $2,000.

I've had 4 supposedly EOS compatible Sigma lenses and one Generic (Made by Sigma) that would not AF on my Canon DSLR's. Only one could be upgraded, and I had to pay $100 for a new chip. I avoid buying Sigma, knowing it could happen again. They have reverse engineered Canon lens software, and may still not have it working such that a minor tweak by Canon to their bodies would cause all the Sigma's to stop working (as in the past).

I'm not really impressed with fuji service at the moment

I sent my x10 in to have the white orb issue fixed. ie replace the sensor with the new fixed one
I left an SD card in the camer with a sample that clearly indicates the issue.

they sent it back saying they could not find the problem :

I've asked if they actually looked at the white orb sample i supplied with the camera

dumb arses

Fuji have had a bad run with releasing cameras with lots of bugs
however that said the last firmware update for the x10 was killer with allowing full customisation of the raw button canon could learn a thing or two here (the raw button was only marginally less useless than the stupid rate button on the 5Dmk3

@NormanBates

The guy does not have a clue about what counterbalance is for, you cannot demonstrate it without a camera, and it is most definately not a self-righting system.

Counterbalance set up properly should have no spring to it at all, the camera should rest immediately as you take any force off the pan bar no matter the tilt.

The benefit of counterbalance is that camera moves become effortless no matter the size and weight of the camera, and provided your head has a smooth fluid cartridge the camera is absolutely still unless you are moving it, you should not be fighting against the force of any spring ever, or you are going to be screwing up your ramping.

You really cannot demonstrate this with zero load.

A unpacking of the T4i by Jared Polin: Canon T4i / 650D Unboxing and Sniff Test

Iliked the fact that he was so impresed by the touch screen and would like to haw it on a pro body.

What also usually works is if you use one of these iced thermal packs for camping or holding food cold in summer and let the lens rest on it with the filter ring having contact with the cold iced surface of the pack for about 5-10 min. Usually the filters goes off without any problem afterwards and you won't need any mechanical force ...

Sorry for the delay in responding! I took a look, and some of it was post-process (had to +1.85 EV in LR4.1 RC2) which was way too much...

OTH, I had some images checked out at the local photography school in a weekend course I was taking, and even just straight conversion images (RAW to JPEG) in the latest version of DPP, there was a ton of grain similar to this, and the instructor used it as an example of excessive digital noise. Also, in my 550D (t2i) I didn't notice the same issue with finding the proper exposure as I'm finding with the 5Dm3. Just seems to expose everything a touch dark.

And thanks for the comments on my son - he's the majority of what I shoot, but I'm branching out now.

Sensors can be bad. They have lots of on sensor electronics for noise removal, and like any electronic item, can be defective or crippled.

Return it for another, never wait until its too late. If you cannot exchange it, send it to Canon with a example of a properly exposed but noisy image. All digital sensors have noise, even at ISO 100, but it should not be noticible until you get to about ISO 800, and then, a tough of nr might sometimes be needed.

My 5D MK III and my Nikon D800 will produce slightly grainy images when viewed 100% at ISO 800 or over with no NR, the D800 is the worst. NR cleans it up nicely, and as long as its very light NR, the image will remain sharp. As soon as you have to use a lot of NR, resolution suffers, but even then, prints at normal sizes will look sharp.
