They should make a light field camera based on this sensor, e.g. with interchangleable lenslet arrays. Lytro projects suffered of low resolution, there 250/16 = 15 mp still left, and 4x more DOF possible

Those features sound like I really want to replace my 70D with an 80D (assuming the DR improvements are really as huge as they are rumored).
Do GAS masks help against this desire? 8)

I'm glad I waited for the 80D (my 50D is in urgent need of replacement) -- it looks like it's just the right update from the 70D (and in a way from the 7DMK2 -- I guess the 7DMK3 will be a killer, but a bit too expensive for me).
Anyway -- from a 50D it's a jump ahead of light years

I would like that although I do not consider it likely. But I believe Canon will be forced to release new updates in much less than 4 years (between releases).

Canon has stated the opposite is their strategy: fewer updates, bigger leaps.

The whole lithium batteries being "banned" on planes seems to pop up every few months on some of the other professional forums I'm on, usually when someone "discovers" the regulations for the first time. Here in the U.S. you haven't been able to check any individual li-ion batts as/in checked baggage(that goes in the baggage compartment under the plane) for a long time now. Period. There are also regulations about what can be brought on/in the passenger compartment, as well. For most consumers and still photographers, it's not a big deal and doesn't really effect you. Guys like me that shoot video, it can. Individual li-ion batteries cannot exceed 100W. Although I usually ship my equipment ahead of me and don't have to worry about, my newest li-ion batteries are 190W, BUT split apart into two 95W halves to meet air travel restrictions.

There are two types of lithium batteries (More than two, actually). Lithium Metal Batteries store the most energy, and when shorted out, they will burn until the lithium is all used up. They are almost impossible to extinguish.

The first bans were for Lithium Metal Batteries.

Then, Lithium - ION batteries started melting down and even starting fires. They are not usually as dangerous as Lithium Metal Batteries, but when several are packed closely together, overheat in one can spread to others, and as a group, they are very dangerous. Even one, packed in a suitcase full of clothing or combustible material can ignite it, so being in a cargo hold of a air-craft is not a good idea. Then throw in the low cost batteries produced in garages and back rooms with no quality control, having those on aircraft is very scary.

Finally, shippers labeling Lithium Metal Batteries as Lithium Ion means dangerous batteries are being shipped in bulk and unsafely. Some are willing to have airline passengers take the risk so they can make money. That's sad, but true.

what type are AA lithium (non-rechargeable) batteries?

You can't discern astigmatism from a large aperture plot of MTF vs spatial frequency. In fact, I would say it is quite the opposite. You also can't do it from small aperture MTF charts unless you know about the lateral color.

Brandon, tell us more about how to discern astigmatism. I know Roger has some good information, but it has long since rolled of my memory chart, which is not all that long anymore.

If you have a lens you know is very well corrected for lateral color (e.g. Zeiss 100/2 makro-planar), you make consider a difference in the tangential and sagittal MTF at closed apertures - perhaps f/8 - to be the astigmatism. At larger apertures, aberrations such as oblique spherical aberration and misalignment-related coma will cloud the view.

If you have a lens - perhaps a 24mm f/1.4, which is much less well corrected for astigmatism, you will have no such luck at any aperture.

However, one may also use monochromatic measurements of the MTF, which removes any lateral color, to tell the astigmatism as well.

Hello guys! For those of you who use Pentax 645d or 645z along with your Canon to shoot outdoor portraits, what do you think about the image/bokeh quality produced by lenses for 645 system? I got some idea from the article by CR member Chris Giles (wockawocka) http://chrisgilesphotography.com/blog/pentax-645z-review-pt3-ccd-vs-cmos/ but I want to hear some other opinions as well, especially in relative comparison to Canon 85 f1.2, 135 f2 and 200 f2.0. Thank to you all.

Click to expand...

Ahh, this was written for me I'll have to find Chris as it would have been nice to talk with him first before buying my Pentax.

I recently bought the 645z. I bought new lenses; Pentax-D FA 645 55mm f/2.8 and Pentax 90mm f/2.8 D FA 645 Macro ED AW SR.

I own 7D's, 5D2's, 5D3's and a 1DX. Canon lenses; all primes from 24mm through 200 f/2 (no TS though). Lots of zooms but the main ones used daily are the 16-35 f/4, 24-70L II, and the 70-200 II.

I'm a working photographer with (portrait, wedding, family).

I haven't had a lot of time on the "Z" but I bought it mainly because I wanted it and not because I need it. I'd have to say the Canon does bokeh much better. The 85L and 135L are probably my most used primes and are hands down better in the bokeh department in my book. So much so that I have rarely if ever pulled the Pentax out for client work (yet). I'm beginning to even think maybe the "D" files look better since borrowing one.

In May we will be in Maui for a month and I intend to take the Pentax as my only landscape camera... that will be my biggest test of it's use as I will also be doing some gigs on the island too. I do wish I had searched out some legacy glass as I know a lot are out there that will work. Do you have any legacy suggestions?

I guess my take home is between the glass I have for the Pentax and Canon... so far the Canon offerings are superb in the bokeh department. The files from the Pentax are quite flat but I actually like that. For outdoor portraiture the sync speed of 1/125 is really no bueno and probably why I rarely if ever shoot with the Pentax+strobes outside or even bring it out to play. Natural light is great but I like the option of both natty and strobe when on the job, here Canon wins hands down. The rest of the story remains to be seen for me.

How is your experience with your rig?

Awesome, thanks a lot for your comments. This is exactly what I needed. My setup used to be Canon 1dx, 85 1.2, 70-200 2.8ii and 200 f2. I sold all of my gear a few months ago to fund my residency program but now my financial situation got better. So, my choice now (i) 5ds (sold at a good price now) and the same lenses I used to have; (ii) Pentax 645d or z; or (iii) new Canon 1dxii with an improved sensor. This is just for outdoor portraits, for fun and not for living.

B and H has been in contact with LucrOit about their 165mm filter system for the Canon 11-24mm lens.
Here's what B and H wrote to me last night...

[font=arial, sans-serif]We have it listed in our database now and the price is $557.60. It is special order only and it will take about 1-2 weeks to arrive. For now you can call to place the order and ask for part number FOPC1124. It will be listed on our website on about 1-2 weeks.
End of Email...

As far as Fotodiox goes on a different thread, we're still waiting word as far as the Fotodiox 186mm filter system will be available over and above their last communication that said probably March. We'll see if that pans out...

In the meantime, there's now a front filter system that will work with the 11-24mm lens with LucrOit that's available right now.

Anyone know why we are getting ripped so bad?

The price is competitive with most countries. Some countries don't add sales tax or a GST which inflate the figure. At around $0.70 against the USD, you're going to see higher AUD prices on most imported stuff than you've been used to in recent years. Glad I bought my 300 f/2.8is when the AUD was at $1.09! It can be a wildly fluctuating currency.

The AUD was lower than it is now when I bought a 1Ds in 2002. Yikes! There was a price drop from $16k down to $12.5k so I jumped on it.

Nikon seem to be laying down the 4K gauntlet to Canon.

Can just released the GX7 II with a decent performance upgrade, but no 4K.

Meanwhile all the new premium compacts from Nikon, Panasonic and Sony now sport 4K.

Canon fans can deny the need for 4K all they want, but King Canute had a similar problem trying to hold back the waves.

I am in the market for a premium compact and these all look more desirable than anything Canon can offer me. Not because of the 4K - that's icing on the cake - but the other features like performance, AF seem a cut above Canon's offerings. Similarly Sony and Panasonic's latest 1" offerings too.

greger · Feb 24, 2016

I bought a 40D and thought I would learn and not be looking for more features. When it became a one shot camera with Error 99 I bought a 7D. I am looking for more from a camera and the 1DX has everything and more. It is a camera that is beyond my reach.

I've created around 150 commercials with my 5D, around 75 percent were shot using RAW from Magic Lantern. The DSLR form factor is great for me, I prefer it over the C100, C300 and Blackmagic. I would be willing to work with the 1DC or 1DX Mark II, for a compressed 8 bit format, the footage is still very gradable and the colors look great out of the box. However, the taller body is not my cup of tea. I'm hoping they bring 4K to the 5D Mark IV and the rest of the cameras here on out, otherwise, I'll need to jump ship soon.

Dust protector on lens mount

To prevent the intrusion of dust and debris into the camera body, the lens mount features a dust protector sealed with optical glass. Additional sealing around the mount further lessens the chance of dust entering the camera body.

Well that's interesting.
So it looks like they have a clip on dust protector inside the lens mount. Basically a replaceable surface for the sensor. As long as they don't let dust in at the factory it actually sounds pretty good.

10 frame buffer for APS-H and 15 frames for APS-C. 3.5fps burst. Not great but I don't partciularly find 3fps limiting on my current body.
They also mention 5fps in "low" mode with one quarter the resolution. It seems like they're binning pixels but they're claiming to write that into a RAW file. I've never heard of that being possible while maintaining actual RAW data, but that might have something to do with the use of the Bayer filter where colour data is based on pixel location.

http://www.sigma-global.com/en/cameras/sd-series/features/
Their explanation of the current Foveon implementation is pretty interesting.

So, red and blue channels are recorded at 6 megapixels, and they use the top layer at 25 Megapixels to give a high resolution luminance map. And I'm guessing blue is deduced by subtracting green and red.

It performed better for me than any of the other Art series lenses I've tested. I actually have a dock now, but I don't have a Sigma lens at the moment to calibrate on it.

Hmm. You know, every day that goes by without an announcement from Canon about the SL2 is bad news - Canon have stopped making the SL1, and they know that the kind of person who bought one of those is probably going to be interested in it's direct replacement. No announcement (or rumour of same) means it is fractionally more likely that there will not be a replacement model - and those who are waiting for an SL2 will start considering the alternatives... :-\

Oh well...wishful thinking.

Good idea! I will go one better and sell my Canon bodies and lenses and upgrade My Sony Xperia to the latest model. Smartphones take so much better pics than DSLR's anyway and you can use all these great effects and put all those excellent shots on Facebook without delay :

Optically, the 100-400 II is better than the 70-200 II + 2x, but probably not sufficiently better to make IQ a deciding factor. Personally, I'd base the decision on other factors... Will you be shooting indoors where f/2.8 would be beneficial? How frequently will you need 400mm? Fiddling with a TC can be a pain, and in my experience the 70-200 + 2x is a bit awkward ergonomically (suboptimal balance, too long for many bags when mounted). But for occasional use, it's fine.

If you're going to spend money, IMO the best travel telezoom is the 70-300L. Wide enough to be of some general use, reasonably long, excellent IQ, smaller and lighter than the 70-200/2.8 or 100-400, and important for me it fits 'vertically' in most camera bags, taking up only one lens compartment not two.

I have the 70-200/2.8 II, had the 100-400 (original), sold it for lack of use after getting the 600 II and 70-300L, and have no real desire for the 100-400 II.

I have both, but I question the number of times you can use a long lens on the pacific coast. There is often haze in the air, so you will need not only the right subject, but the right atmosphere conditions. I grew up near the coast (Near Westport, WA, and have been to the beach countless times. I can only recall a few times without fog or haze to some degree, and always wind and sand in the air. Be sure to keep a filter on the lens, and a polarizer for water shots. I will say that the Long Beach, WA has better weather and clearer days than the areas further North. I had a tough time believing their 78 degree temperature two weeks ago though.

If you want to shoot birds in flight or seals, or other distant objects, the 100-400 plus 1.4 TC is best.

I suspect that wider shots will be your mainstay.

+10

Some really good points in this thread.
So, I need the polarizer and stuff?

(
I was hoping to do all that in DxO or LR6.
More stuff I don't have.
