A New Flash by Years End? [CR2]

I don't see the triggers being anything like the bargain priced accessories we currently see.

Looking at the price of the current YN proprietary triggers, there shouldn't be much of a price difference for the rt version - it's rally just some cents of electronics in a plastic casing, they don't even have the lcd display of the st-e3.

That would be a fair comment if cost per unit had nothing to do with perceived value per unit. Do you really think a YN-622 costs anywhere near four times as much to make as an RF-603? An RT YN-642 trigger would cost appreciably more than the 622, even if i was only £20 more that still takes it to £100 for wireless control of one flash, hardly the budget option that the RF-602 got us into at $25 a set.

If they didn't do the LCD it would be considerably less attractive, the ST-E2 doesn't have one so the 622 doesn't need one, but the RT system has much more functionality and digging through the camera flash menu becomes a chore with all the enhancements.

The way I see it whilst some people will always be excited at saving a few hundred dollars (or a hundred quid or so) once people start using the stuff and limitations start showing up then people see less value in third party, no new RT system option will be cheap and whereas with the current third party radio ETTL control that offers something Canon never did, going against direct competition with less functionality, as opposed to no competition with enhanced functionality, seems to make little sense to me.

But as I said, I have been wrong many times before.

ETTR or ETTL?

ETTR makea sense mostly at ISO 100. With Canon however, it makes sense at ISO 200-800 as well. The idea is to let as much light possible but still keeping the highlights you want to keep. This is not easy since the histogram may show clipping but the RAW may not be clipped. Also, with certain colors like red, that color channel may be clipped even if the histogram looks OK.

I keep my 5D2 at EV=+1/3. This is a lazy way to expose a bit to the right, and to compensate for the conservative metering of my camera. When the SS is not a problem, I would overexpose a bit further until I see a brighter shot on the back screen - how bright - it is based on experience, not on the histogram really. This is very important (to me, anyway) for shots with a high DR or for ones which I expect to pp heavily. Sometimes I blow the highlights, unfortunately. My most viewed shot on Flickr has severely blown highlights.

The benefits of ETTR is not only lower shadow noise but lower shot noise. With strong pp, WB tweaks, vignetting corrections, etc., that noise may become visible even at ISO 100. With crop cameras, it takes very little to reveal it.

At higher but moderate ISO, it is better, for example, to shoot at ISO 800 to the right, if you can keep the highlights, than at ISO 400. The reason for it is - well, it is a Canon sensor. The read noise at ISO 800 is roughly speaking 1/2 of that at ISO 400 but you get no benefits form lower shot noise, of course (same exposure). This is counter-intuitive since you would expect that you should stick to the lower ISO if you can. You take more risk, as well, since metering in low light may not be so accurate, DR might be higher, and you can easily blow the highlights.

Canon always need to move forward and get people to spend ever larger amounts of money with them, so after FF, where else is there to go except to MF?

So, you're saying there is a huge block of Canon users who have upgraded their way to 1DX and want more camera?

Yep.

MF isn't about wondering the streets taking snaps of pigeons or taking photo's of your kids pricking about in the garden, it's a serious camera for serious people. It's a commercial camera for commercial projects, product, architecture & fashion. Imagine cropping an image and it still being big enough to print on a billboard or the side of a building. That's it's practical use. The photographers who do this aren't going out to do weddings at £100 a pop.

Don't get disgruntled because this camera isn't aimed at you. It's great that they're having a go at this market and I can't wait to own one :)

I guarantee there will be a segment of the market using these to put funny captions on pictures of cats.

I know that's why I want one, getting action shots indoors is a real struggle (thus, I've never posted any funny cat pictures).
And the Bokeh! crowd will go bonkers.

I am the Bokeh! crowd... why have everything in focus when you can have almost nothing in focus??

Checking Real Focal Length - 70-300l

Jens_T said:
Hello,

today I bought the EF70-300L lense to replace my old Tamron 70-300VC. When playing around I noticed that the 300mm on the Canon seem to be a good bit wider than on my Tamron.

Is there a website that actually checks the "nominal" focal length? I remember Lensrentals sometimes comments on the the real focal length but they don't list the details.

Or is there a simple way to calculate it without too much hassle?

Thanks in advance
jens

The 70-300L has a TON of focus breathing and the Tamron has VERY little. At MFD the 70-300L turns 300mm into only 200mm! At 25' it is still only about 282mm. Even at 50' is still doesn't seem to yet reach 300mm. Maybe on the moon it does ;D. Or maybe never. Even shooting across the length of a soccer field, the long way, the old simga 120-300mm seemed to deliver about 280mm if what you call the 300 2.8 IS delivering at 300mm at that distance. (the sigma also seemed to be about f/3.0 if you call the 300 2.8 IS f/2.8) and the difference seemed to be about the same shooting much closer in too so I think the old sigma 120-300mm was simply really a 120-280mm f/3.0 lens ;D.


At 25' I had to set it to read EXIF 72mm to get same FOV of the 70-200 f/4 IS at 70mm.

How strong is the hotshoe?

Grab a kit by a flash and your flash will be destroyed...

Depends on the kit. I grab and carry by the 600EX-RT...when I have one of my flashes mounted on the EOS M + 22mm f/2. :)

I think the 600EX also qualifies as the heavier or more expensive component. Glad to see I'm not the only one who does this with the M+22 combo. I mean really - what else is there to hold it by.

70D vs D7100 ISO Comparison at 100%

Mikael, you are hereby banned for life. Don't make a new account, don't come back. You will be noticed, and we're not going to give you another chance.

You are knowledgeable and and can bring a much needed voice of dissent at times, and because of that we regret doing this, but you bring out the worst in everyone here, and your behavior can no longer be tolerated.

EVERYONE ELSE....

Your behavior in this thread has been no better. You should be ashamed of yourselves. Act like adults, and have civil discussions.

Wide IS lenses - price drop!

brad-man said:
Yes. Once again, it's all about the money. The three IS primes are indeed fine lenses. But they are/were overpriced for anyone who does not have a definite need for a lens with those characteristics. Does that sound a little like the saga of the EOS M? For casual amature photographers they are simply too expensive. For most enthusiasts and pros, they are too slow (again, for the money). Personally, I would love to have the 24 and the 35 for the sake of convenience, but I have those ranges competently covered. If these new prices are indeed "permanent", then when a sale/rebates come around, or they start showing up as refurbs, I will take another look. I suspect I'm not alone here...

Have to disagree. These lenses are for FF users -- so you can't compare them to EF-S primes (there is only that one macro EF-S prime, after all). Further, they are not 'way more pricey than the versions they are replacing', they are 'way cheaper than the corresponding L versions'.

For the extra money for the 24L ($1749) and 35L ($1479) -- both great lenses -- you get that extra bit of build quality and two stops... of relatively soft performance. And in my hands, I never shoot wider than F/2 at those lengths, so half that upside is unnecessary with my 28mm. I'll take the 3-4 stops of IS over one faster stop (F/2, again, just what I do) any day.

I'm not saying that they are the best lenses on the market, but for the apertures I shoot, they are just as sharp as the L glass at less than half the price. That's a great value proposition to me.

I would expect the rumored 50 F/1.8 IS to similarly start high (guess $800) and walk down to $600 after a year.

Best telephoto clarity for the money

neuroanatomist said:
If you can get a high enough shutter speed with the 400/5.6, that's sharper than the 300/4. Both are very slightly sharper than the 100-400, but there is copy variation to consider, so you may find some 100-400s that best the 400/5.6. The 70-300L is sharper than all three.

Wide open, yes. But at 300mm f/5.6 (the best both zooms can do at that focal length), the ISO 12233 test chart appears to show the prime being sharpest, followed by the 70-300L and then the 100-400.

What settings would yall suggest for a new born in a hospital?

AcutancePhotography said:

I think putting the camera on green box automatic. It is not reasonable to expect a newborn to be able to manually adjust aperature or shutter speed. The newborn is going to have enough problems just holding the camera.

:D

funny. if I wasn't at work I would have laughed aloud.

Travel Advice to National Parks in Utah

So glad you asked. I made a little apparatus for a similar need. Mine was intended to avoid damage during a cross-country move, but it should do fine for your needs.

Get PVC -- the large diameter, thick-walled stuff and a pair of rubber end-caps. A local hardware store might not have it, you might have to go to a big box like Home Depot, Lowe's or Menard's. It'll be in the plumbing section.

Top tip: bring your tripod (with head attached) into the store for a trial fitting.

See pics for the one I made. It will rattle around in there, so you may want to wrap it with a towel. Also, though I didn't make one, you can easily imagine a simple fabric loop you could attach for a carrying handle. And, in your application, don't forget to put a name/address tag on it!

Total cost ran me about $15 if memory serves.

Have at it!

More Canon Pancakes ?

Sporgon said:
I'd like a 50mm pancake f2.

Although they never called it a pancake the Nikkor 50mm f2 from 1977 to about 1979 was pretty well a pancake lens fitted (deep) into a normal 50mm 1.4 body. By far the best 50mm I have ever used.

Yes!
An extra stop of light on the Pancake would do wonders, and 40mm is a little short for my taste, though being the widest lens I own at the moment means it gets used for a lot for landscape pictures.
If they could keep the close MFD that would be great too.

Storage and life of batteries

Hi,

Have been lurking for a few weeks, and joined specifically to ask about battery life. I'm an enthusiast, graduated from EOS 1000 to 60 last year, and have just inherited my Dad's 5Dii. It has seen under 5k actuations, and he got it as a retirement present 2.5 years ago (upgrading from a 20D).

The batteries in my 60D typically lasted 700+ - I rarely had to worry about charge status. The first thing I did when I got the 5Dii last week was install magic lantern - have never used it before, but thought that a clean slate would be a better learning experience. Might have been wrong on that.

I noticed that his batteries seemed to be draining very quickly the last couple of days as I was getting used to it and setting things up. Took it out today and took one of mine out as a spare, as the first battery was at about 30% - after less than 150 shots total, I had to replace the first one and the second is now at 69%. This seems horrendous - even with plenty of chimping as I'm checking things out.

Is the 5Dii battery hunggry? Surely not...
Does Magic Lantern hoover up charge? Can't think why...
Is there some setting I've missed likely to have caused this? Possible, but it must be pretty power hungry...

Any input gratefully received!

Really loving FF + 24-105 btw.

Canon is going to add mid format

pedro said:
some additional news over at NL
18th We're told (thanks) that nothing will appear in any Canon branded MF range until there are enough items to introduce it as a 'system'. This will include 'Canon designed' [sic.] lenses with a new larger version of the EF mount (tentatively called EF-L) and, as with the EOS-M EF->EF-M adapter, a way to allow them to be used seamlessly as very high quality lenses on the current EF mount.
The lens development is being influenced by the new range of 'Cinema' lenses (I note their prices!)
The aim is a 'show stealing' announcement at Photokina next year, but no details on when any cameras might be offered for sale.
I've seen other related comments (thanks) which emphasise that this is still at a relatively early stage and the business relevance has not been established.
My own thoughts are that with the recent decline in DSLR sales, this might be a tricky one to get a good return on the necessary investment?
http://www.northlight-images.co.uk/canon_medium_format_2ff.html


"EF-L" seems like a terribly choice of name, given the likely confusion with "L" lenses, unless all MF lenses will be "L".

Perhaps "EF-66" would be a better choice, assuming they retain the 6x6 format for the notional MF camera.
