Samyang/Rokinon vs. straight lines.

Thank you Random. From Dustin:
"The truth of the matter is that this little lens is in most ways a better, more complete version of the big brother 14mm f/2.8. It has far less distortion (which means that the extreme corners are useful), similar sharpness, and (this is a biggie) can use traditional filters in a common (and relatively inexpensive) size.

Interesting ... user of long-discontinued heavy-as-a-brick Pentax 645 medium format film camera calls massively popular digital point & shoots an "epic fail" because assembled from "out-dated" spare parts. :)

Please, dont feel intimidated by the revelation of modus operandi of many manufacturers from many different industries.
Money = Good. Spare Parts laying around = Bad.

I wish you a fantastic journey with your photography, a lifetime of great images, and more. Dont forget that Photography is a form of Self Expression, and your images are revealing.

Enjoy !

Yes, I'll enjoy, thank you. Your "revelation" was that these new cameras are somehow an "epic fail". I'll grant that perhaps you know something about out-dated spare parts at the Canon factory. But I'm not sure how that fits in with your view of photography as self expression. The "epic fail" was because one can't make expressive photos with these new cameras?

Sony is desperate, or think we are idiots?

ajfotofilmagem said:
It seems that Sony really is on the verge of bankruptcy. They had the idea to revive the Walkman in a digital version that costs 1.2 thousand U.S. dollars! :o :o

I assume that you have never compared prices between a consumer grade CD player and an audiophile CD transport, outboard DAC, power supply and connecting cables?

The Mark Levinson No 31 still commands north of $3k USD and that is over a decade old.

I have listened to a CD played through $200k in gear and cables (not my stuff, unfortunately).

At $1,200, this is nothing in the audiophile market.

Expect Higher End Products at CP+ in February

"Having a catalog of a 100 lenses means nothing if almost everyone only uses a selection of about half a dozen of those." ==> Mr. A needs 16-200mm fL. Mr. B needs 200-800mm fl. Mr. C needs TS-E lenses etc. Looks like Canon/DSLR offers much better selection for all users.

That is quite true!
I am a Mr.C who likes the TSE-17 mm so much which other brands d not have!
If they had it I would seriously think about a change of brand.

Help needed with filters for my 70D 18-135mm IS STM

I have a B+H UV filter on my 18-135 STM. For $40 I thought it was a good deal.
http://mobile.adorama.com/BW67UVM.html?utm_source=Transactional&utm_medium=Email&utm_campaign=ShippingConfirmation&utm_referrer=direct%2Fnot%20provided

I have a Hoya CP filter that I have had for a few years. When I get the 10-18 STM lens I will probably get a nicer CP.

Enjoy the 70D. I am loving mine.

Kodak's first smartphone. Will Canon follow?

pdirestajr said:
Isn't it just some random tech company sourcing cheap crap from China and slapping the Kodak license on it? I doubt "Kodak" is doing much of anything.

I thought they went under, administrators then sold all the bits.. on going businesses, name and so on.

I know the sensor business got sold.

Who are Kodak these days?

Traveling to Europe... debating what gear to bring. DSLR or EOS M?

mangobutter said:
You guys have convinced me to take the 6D. Why not, right? I guess if anything would break, it would be a mirrorless camera versus a tank of an SLR. [...] Also it WILL be raining a lot in London so this is when I'd put the EOS M away.

Make no mistake: The 6d's weather sealing is very weak, if you shoot in rain you're gambling with your camera since the warranty doesn't cover that damage! You might be lucky, but then again you might be not - better get a rain cover or use a bag from the supermarket.

mangobutter said:
I'll bring the 50mm 1.8 for when I need a "perfectionist" shot (sharpest possible IQ).

Are you sure we're talking about the same lens :-p ... 50/1.8 and "sharpest possible iq" doesn't compute.

What is your favorite lens/camera combo in your camerabag?

Surapon,

On the photo you posted of the Big White, what is mounted on the center of the lens?

It is two Frio cold shoes on his big flash bracket, with a spirit level on for good measure.

Thank you. I enjoy seeing what other people use because it helps me determine what I "need" ;D

EF lens design shrunk to EF-M specs

Mika said:
Generally speaking, optics tend to work fine with downscaling. In the case of EF-M, yes that would indeed be possible. But the question is, does it make sense to do that? Occasionally, downscaling from full-frame's 43.2 mm image diagonal to 21.6 mm diagonal makes aberration correction (astigmatism and coma) easier by roughly a factor of four.

This tends to allow a reduction in the number of components in the objective, thus reduction in the price. So a designer might find himself in a situation that he can take away one lens from the formula without affecting anything much, or with only small performance degradations. Without a very good reason, this is often the case that happens.

For example, take a look at Sigma's 30/1.4 Art (DC=APS-C) and at Sigma's 35 50/1.4 Art (DG=FF) where the number of lenses is noticeably less in the 30 mm version. This did come with a slight compromise on the lens performance, though.

Does this answer your question?

EDIT: Oh, forgot to mention that upscaling an optical design doesn't work as nicely as typically the optical aberrations increase at least quadratically, so the general rule is down-scaling is OK, up-scaling isn't.

EDIT^2: Mika isn't paying attention today. Of course it should say 30/1.4 Art and 50/1.4 Art as we are talking about comparable FOV with scaling...


this does answer my question. thank you.

5DIII AF Point Issue (addendum..resolution)

tpatana said:
Stop scaring me!

Had to try mine. It was almost dead on. However, using the 24-105, if I turned off the IS, then the AF point always shifted ~1/5 upwards. Strange. Did about 10 both ways, IS-ON was ok, IS-OFF was slightly up always.

Btw., what's the FW they installed? Wouldn't be the first time the service uses pre-release of something that's coming out in public some time later.

If's it's different than what we have, you need to go through all menus to check if you can find any changes.

...tried mine as well (using the viewfinder and center-point, and live-view and center-point)...and ended up having to google 'parallax view' (not the movie!).

My 5dMkIII is perfect using live-view LCD center-point focus, but depending on the position of my eye at the viewfinder I could induce a bit of parallax which caused just a bit of off-set in the downward and left-hand direction. I wear prescription lenses and I suspect this contributes to the problem, too.

So I think it is worth testing this AF Point Issue using the LCD and live-view before sending your body off to Canon.

Samsung NX400 with NX1 BSI sensor

Khufu said:
wickidwombat said:
that looks nice!

any idea if you can get adapters to use EF-M lenses?
i could see this living attached to my 11-22...

very much doubt it, buddy... the NX flange distance is greater than the EF-M mount!
Also, with all the wire-focusing/aperture control etc in these MILC systems I can't imagine we'll be seeing inter-system compatibility adapters in a hurry!

bummer but it will be interesting to see how this lens performs

Samsung S 11-24mm f/2.8 ED OIS

so far the indications of the IQ and the AF performance of the NX1 really make
me have a good hard look at this upcoming little brother

50 f/1.2L problems applicable to 85 f/1.2L?

Maiaibing said:
zlatko said:
the focus shift is so easy to avoid

Great that you are happy with the lens. For the price I'm just not as forgiving.

Happy shooting!

Yes, I'm happy with the lens because it has an exceptionally beautiful way of drawing. It was good enough for Mario Sorrenti shooting the 2012 Pirelli Calendar (NSFW) -- https://www.youtube.com/watch?v=gjjF5yQmVw4 -- He used it along with the 24-70 and a Hasselblad. It's good enough for photojournalist David Burnett and others.

Canon Updates Compact, Powerful VIXIA HF R-Series Camcorders

I have a 2012 model Vixia and it is an excellent camera even for today's standards. Unfortunately, that is pretty unacceptable for a 2015 model.

Not really. Current "Excellent" video quality standards for consumer HD were set by the Sony RX10, which was announced in October 2013. Video from the Exmor sensor is outstanding, and has been successively improved by later cameras with the same sensor family. I have a RX100M3, and the quality of the video from it blows away that from my HF G30. The RX100 does not have a comparable lens of course but it does set the standard for the minimum anyone should be expecting from a video camera in 2015. The so called "new" R60/R62 will produce the same limited quality that Canon camcorders have been producing since at least 2012, and that simply is unacceptable.

In fairness and comparing apples to apples, this would be a P/S cameras vs camcorders.

Am thinking that camera sensors in many cases best consumer hd camcorders especially those in the canon consumer vixia line. To your point, the specs of the HF G30 looks almost exactly like the consumer grade HF M and R lineup minus the audio bonuses.

Superficially the G30 has similar specs, but mechanically it is much better than the R series. It has a bigger sensor and a much better lens, it has an EFV, better controls etc etc. The G30 is the same camera as the XA20/XA25 however, just with a few less mechanical add-ons. In fact, it has the same innards as the XF200/XF205 as well (those have different shells and a few extra encoding options).
