xlynx9: This is the most interesting news I've seen here in years.

yepp, IQ might need a decent improvement within the first generations, but surely this is very interesting.

On Tamron SP 150-600mm F/5-6.3 Di VC USD Lab Test Review preview (198 comments in total)
In reply to:

Picturenaut: For all birders and wildlife photographers: in Scandinavia, after shooting atlantic puffins, I had a brief talk with a guy using the Tammy with an EOS 7D. Overall he was quite happy with this lens and its IQ, in particular in terms of price-performance ratio. The only drawback is AF performance. He said that he had completely given up to try birds in flight with this lens. I have to add that even with a Canon supertele it is a real challenge to get a good BIF pic of those speedy little puffings (they fly with about 80 km/h), but it is not impossible.

So the AF performance of the Tammy is a limitation at least birders should be aware of. Otherwise this lens is so attractive that I personally still think about getting me a copy for those trips I can't take my 500 mm prime with me/ I want zoom flexibility.

That's good news as they might be able to improve a Tammy's AF performance step by step with this and future firmware updates. Tamron like Sigma and other 3rd party lens makers have the problem, that they have to re-engineer Canon's and Nikon's AF systems. Otherwise they would have to pay them a lot of money to use their native AF control parameters.

On Mountain Magic: Shooting in the Lofoten Islands article (62 comments in total)

Good images, nicely captured atmosphere. I personally like the composition of most of them, Erez has good eye for structures.

I read the critics of some posters here with great interest. If bford & Co. think that they are more skilled landscape photographers, they really should come up with own examples. C'mon bford & Co., show some of your fantastic images! I think most of the readers here are happy to learn...

On Nikon D810 Preview preview (1096 comments in total)

DSC_8558 impressed me most: looks like the D810 is the sweetest pastry-shooting DSLR in the world. Good news for pastry shooters!

The history of this image is very interesting, it shows how iconic pictures have been manipulated already in analogue film age. Like other such shots with a lot of symbolism it had been re-enacted a few days after Soviet soldiers put up the first flag on the Reichstag. Later, Khaldei's image has been "post-processed", smoke added, stolen watch from the wrist of one of the soldiers removed... Post-Photoshop age hadn't been a paradise of pureness and honesty...

On In Photos: Iceland captured in infrared article (67 comments in total)

wonderful images, it looks as they show a mixture of both NIR and visible light. I personally like the heavy vignetting much,it enhances the drama and turns Andy Lee's great images into real art work IMHO.

On A travel-sized large-format 4x5 camera? article (218 comments in total)
In reply to:

rfsIII: This is so awesome. Here in the United Snakes 25 sheets of 4x5 film is $30 or $40 plus $3 or $4 per sheet to process. If you have the time to shoot it beats the cost of buying a Hasselblad or a Phase digital.
And the people here obsessed with shallow depth of field will love it because at normal apertures like f/5.6 your DOF is measured in fractions of an inch.

Yes the price per image drives you to think first carefully and then push the button. It's basically a move from snap-shooting to real photography - but only if you have the right tool. Therefore I'd rather prefer a used 4x5 film Fuji Rangefinder or Hassi, Mamyia, Pentax, Yashica SLRs... with a good lens. On ebay e.g. are plenty offered for quite decent prices. This Wanderlust thing looks more like a 3D printer's joke.

David Hurt: I NEVER EVER use a Lens cap ! ! !

yeah, I agree. A good lens needs frequent front lens sanding anyway, keeps it clean and enhances bokeh...

glue a piece of velcro on your lens cap and a second one on a clip and you have the same result with a few cents investment. Doesn't look so fancy of course.

justmeMN: Canon estimates that they will sell 7.6 million DSLRs and 10.5 million compact cameras in 2014. Not bad for a company that does everything wrong. :-)

"Fortune" seems to think differently...

When I saw the wonderful portraits of the Nikon guys here I immediately stopped wondering about how the Nikon DF's design came to see the light of the day... ;-)

Lux Painter: Either Canon is going to release their own smartphone (so the smartphone is not an enemy) or they are in total denial (more likely)

Smartphones are no option for Canon + Nikon, because they'd need a bigger consumer electronics section such as Samsung and Sony have. Smartphone camera modules are technologically and economically quite different from classic camera manufacturing. The makers of those modules have to cope with selling a lot units with close to zero margins, it is a bit like automotive supplier's business.

topstuff: Whats this about Americans not liking small cameras?

It is bizarre. Do Americans think that large = better?

Makes no sense. No sense at all.

In particular in arabian countries a bigger gear is more respected (like bigger cars). My wife was some months in Qatar and used her Nikon DSLR + e.g. a 300mm/4 for birding, and people were impressed.

Would be interesting to get an update of this report including Sony's sales figures.

Reading all those posts here I am amazed to see how many people exactly know what the industry is doing wrong. So, maybe they should fire their CEOs and hire one of those masterminds posting here?

"So conventional DSLR users buy more lenses. Mirrorless camera users are more likely to purchase the camera with a kit lens and not many people purchase any additional lenses. Some high-end mirrorless users with Sony NEX-7 or Olympus OM-D buy more but the majority of mirrorless users are the entry-class users."

This explains exactly why Canikon hesitates to move boldly into the mirrorless market, and why e.g. Canon comes up so slowly with new lenses for the M system. For most users their mirrorless cameras are a sort of new compact with better IQ. Interestingly even entry DLSR users obviously tend more to get at least one second lens. Obviously most customers are conservative, and only SLR type cameras represent for them a real system camera.

On Configuring your 5D Mark III AF for fast action article (6 comments in total)
In reply to:

Picturenaut: Great article, great shots, mini23. I worked out about the same settings doing BIF etc. Btw the lack of any comments so far shows that dpreview ceased to be a forum for wildlife shooting (if it ever was one).

Just let me add a little warning for a minority of those readers who still use a vintage EF 500mm F/4.5 like me: do NOT try to set "Lens drive when AF impossible: OFF". First, your 5D3 won't let you do that with this lens attached. But if you switched your camera off and then on again, stangely the camera accepts this setting but the lens' AF/MF drive is completely dead. Fortunately if this happens the 5D3 accepts resetting "Lens drive when AF impossible: ON". I think the reason for this strange behavior is the vintage full drive-by-wire focusing system of this lens.

Any other settings described in this article work perfectly.

Thx, didn't check canonrumors for a while because I really was pushed-off by all those stealthy Canon haters posting there (therefore I never registered there). Looks like canonrumors starts to be a useful forum for Canon users (not fanboys) again.

On Canon EOS 70D Review preview (624 comments in total)
In reply to:

Gesture: What a better value/approach if one is buying an older model: Say, get the 50D or a more recent but not latest in the Rebel Series, say T4i. Thanks.

The 50D is technically quite outdated, its not only the lack of video but noise performance isn't top of the notch. That said, the 50D is a tough, reliable workhorse in a rugged body that still can produce very nice images. Sold mine to friends, and they are very happy with it.

Btw magic lantern offers a video hack for the 50D. The only drawback is that you need an external audio recorder...
