and not to forget about moire either, now that is something that will actually ruin images whereas an AA filter will make then slightly less crisp.

The f/4 IS is sharper than the f/2.8 IS, the latter is bigger and heavier.  If you don't need f/2.8 for indoor sports or subject isolation for portraits, I'd stick with the f/4.

But stopping down to f4 they are very similar. There's no arguing with the weight difference though

Interesting, I can imagine some canon execs being a bit sweaty right now

thanks for the info.  I'm only working with a canon rebel - have for five years now.  I have a full frame coming on Friday, finally decided to upgrade to the 6d. So on top of strobe lighting to learn, I will get to learn a new camera too.   This next one was taken with my canon rebel - 50mm 1.8  (ISO 200, F3.5 and shutter 1/200) All in all the color is flat but it looks "natural" lighting wise and that is what I'm going for.  I will just keep playing around until I get the look I like.  I used both bee's and both softboxes with this one.

First step would be to stop down to at least f8, probably f11 or so would be better. Keep iso at 100 and you can easily keep shutter speed a bit lower such as 1/50-1/100th to be certain there is no chance of black bars in the photo.

The important thing to realise with strobe photography is that only the aperture and the iso will affect how much light is on the subject, shutter speed will only make a difference if there is ambient light to consider which you probably won't have much of in a studio. Since you are using mains powered strobes there is really no reason to go above the best performing ISO which for canons is either 100 or 160 depening on model. Aim for a small aperture as you want them sharp. If your backdrop is wrinkly stand them further away and put a light on it as much as possibly from a perpendicular angle as it "smooths" out the creases. Having them stood away from the backdrop will also mean that you don't get their shadows on it.

As more of a general tip, the photo you posted makes my eyes really confused as you have the leaning kid, the leaning stripes from the floor and a large straight watermark. Having photos at a slant very rarely makes them better.

I use my 1d in P mode, but only when using on camera TTL flash. I'm sure it'll make someone want to harm me for it but still... P mode works well when you are using slow lenses, especially with variable aperture like the kit lenses

I agree holding the lens the wrong way around annoys me but then so do lots of other things other people with cameras do. 1) Having the lens hood on the lens but in reverse position and the lens cap on, preferably on a piece of string. 2) Rotating the camera the wrong way, the best was the guy with a gripped 5dII who rather than using the extra shutter button, used the normal one as he was rotating the wrong way. 3) people who frame subjects with the face in the centre and then never crop their photos. Inevitably feet will be cut off.

What about a 4D? It's just a matter of time :)

No then all the Physicists would get confused they might think it were referring to advanced hypothetical spacial relationships beyond the current acknowledged 3 Dimensions...  :-*

erm, you mean four? Or was it eleven

I'll bite on this...

I think you make some very valid points.

Of course, only time will tell. But I have a hard time imagining that even with the presumed cost reductions in sensors (which folks more knowledgeable than I am have said are unlikely to be significant in the foreseeable future), that Medium Format will overcome the other limitations you reference, particularly because some of the limits result from the basic physics of the size.

I'm also not quite so anxious to presume the death of APS-C. I think it is always risky to bet against "good enough" in favor of "better." There are junkyards full of products that were better that lost out to good enough.

It's hard to look at the current quality of APS-C sensors, the relative sales and the 100-year plus march towards ever smaller and more efficient electronics and believe that the long-term trend will be towards larger, rather than smaller.

I think we may be better able to see the future of the crop format when the 7DII finally surfaces.

Looking at the medium format market today, it takes quite a leap of faith to think it will break out of the narrow niche that it lives in currently.

Still, I think your observations are valid and I certainly appreciate the way you have articulated them in a fair and unemotional manner.

Good job.

Oddly enough, i think that the transition is more likely because of the very advancements you speak of.  sensors smaller than APS-C are getting better and better, as are the optics in cell phone cameras.  So APS-C is going to have to get a whole lot better, or, be phased out ---this is within a decade mind you.  I'm not one of the physics masters here, but how much more can the APS-C be pushed?

Does aps-c really need to get any better though? I would like to think that in 2008 with the introduction of the 40D, aps-c reached the level it needed to be at for the vast majority of customers . The addition of video and some better circuitry for higher max iso could have been done for that sensor and it would have been good enough even today, at least if you could convince people 10mpix is enough.

If we can get smaller and lighter FF cameras selling at the x0D price point with matching lenses I think more people will buy into FF. My old eos 300v for example is the same size as an x00D with the lens only being marginally bigger than the kit lens of a crop camera. Given that the electronics is getting getting smaller by the day it is about time someone built a camera like that.

MF however is less likely to catch on simply because of the portability issues, never mind the cost. There is no way to get around the fact that bigger chips have an exponentially lower yield in production and that the bigger the chip the fewer you can fit on a wafer which also drives up cost. The first problem you can get around if they can work out how to build the sensor from smaller subsensors without loss of image quality. This would also increase the number of assembled chips per wafer as smaller chips are easier to fill the round wafer with. There's still no good way to sort out the lens size though if you want a slr construction. The mirror box is also going to be bigger which means a deeper body and longer flange distances for the lenses which obviously brings problems of its own. 35mm format or better still aps-c is going to be difficult to beat for the sweet spot of portability vs IQ that most people buying a DSLR are looking for.

If someone builds a relatively compact MF rangefinder type camera with a good EVF and the sensor is assembled from smaller sections and it is sold for under $1000 it may get mass market appeal. For less than $3k the enthusiasts will flock. Less than $5k you'd probably attract some pros. I just don't think that the cost will drop enough for this to happen in the near future.

Lenses / Re: How much will the new EF 800 f/5.6L IS II cost?
« on: March 24, 2014, 07:02:31 PM »
The majority of the market for a 800mm f5.6 isn't really going to be bothered about what it costs as long as it isn't outrageous. If the lens is better than the previous version they will upgrade to the new without a doubt. A few thousand dollar isn't here nor there for this end of the market and as a result canon will charge whatever the monkey throwing the darts comes up with.

Actually, it probably has really huge pixels. There are Kodak astro CCDs that have 9µm and 24µm square pixels. If we figure that the pixel sizes for this 8x10 sensor are somewhere around there, the guy has ~640mp @ 9µm, and ~90mp @ 24µm. I figure, just from a space and processing standpoint, the pixels would have to be garganguan. I think 24µm pixels sounds more reasonable, and I guess it's possible they were larger than that. So this guy is taking maybe 70-90 megapixel photos with a giant 8x10 sensor with pixels that probably have about 12 times the sensitivity as the 1D X sensor. That would make full well capacity per pixel around 1.1me- to  1.5me-...WOW. Dynamic range on that sucker must be like, 150dB! :P

In the comments he says it takes photos of about 10 mpix. Yup, ten megapixels.

How many apple-esque stores have Canon opened so far, was there not an announcement some time ago about them doing that?

I thought they were opening one in London but I have yet to see a sign of it appearing.

I have a couple of friends with nikons and I always get confused doing even simple adjustments. I am jealous of their 35 and 50mm lenses though

I had the same debate as you did. I love my primes but also had a canon 24-70 v ii. So I took the 24-70 v ii and my sigma 35 art and ended up only using my 35 because it is perfect walk around lens. I found that I had no use for the zoom and ended up selling it and sticking with just primes. I traveled to Spain and Italy over a year ago and only used the sigma 35 art. Heres the link

I think someone has hacked your website, there is now a lot of ads for various male enhancement pills and my antivirus went into full alert

Excellent news, smaller lithography of flash memory will make them cheaper, more energy efficient and pave way for even bigger capacities

So much for canon not inventing

I'm not surprised in the slightest. The chinese manufacturers seem to have taken a very big chunk out of the enthusiast market and some pros aren't averse to using yongnuo et al either

I would've thought it would have made a logical business partnership for Canon or Nikon to pair with a cell phone company to handle the camera function.  Seems like a no brainer.

It would make a lot of sense for canon since they have the entire production assembly for it. It would be pretty easy to whack the small P&S sensor into a phone, just look at the latest sony phone which has a bigger than usual sensor.
