I use a lensbaby composer sometimes as a mind opener when I get stick with my usual ways of photography. Street shooting with it on FF is a crazy experience, in particular if you try to get moving people into the sharp "sweet" spot. The results can be everything between breathtakingly awful and stunningly beautiful. Using a lensbaby can be an effective cure for creative blocks caused by perfectionism...

You'll also need an additional budget for paying some sherpas to carry this nice travel lens ;-).

kodachromeguy: "Longest lens in the world?" Maybe the longest physical lens for 35mm format, but Nikon made a 2000mm lens years ago for manual focus Nikon F mount. The Leica R (or M) 800mm f/6.3 APO-Telyt-S may have been almost as long physically because the Leica was not a telephoto lens, it was a long focal length lens.

Canon made a 5200 mm prototype lens for FD mount:

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.

Didn't check this but I guess that the old Tamron 200-500 might have much less lenses included than the new 150-600. I understand that the new construction is quite sophisticated. More optical glass means more weight (the new Tammy has a plastic housing).

Re the Sigma "wide aperture" 300-600 we can only say now: it's all rumors, nothing else...

On Tamron SP 150-600mm F/5-6.3 Di VC USD Lab Test Review preview (217 comments in total)

Yesterday we had the chance to test this Tammy in a shop in Frankfurt (Germany) both with our Canon and Nikon gear and bought a copy with Nikon mount. AF performance with the Nikon (D300S) was quite good out of the box. With our Canons it was a mixed bag. AF performance of the test copy was overall okay with our 7D, but not with our 5D3.

Checking the test images I noticed that the lens was heavily backfocusing on the long end with the 5D3 and would have needed severe microadjustment. I remembered that Bryan Carnathan reported the same issue in his great review:
http://www.the-digital-picture.com/Reviews/Tamron-150-600mm-f-5-6.3-Di-VC-USD-Lens.aspx

Overall I agree with Brian's findings after this brief test. The Tammy is no match for a good prime supertele on the long end, but delivers surprisingly decent IQ in the 200-500 mm range. One big plus over the Bigma: f = 5.6 already @ 400 mm available. If AF issues can be solved it is definitely a great travel zoom for wildlife shooters.

A Sigma 300-600mm with wider aperture would be quite a beast (depending on the aperture of course) and surely located in a different market in terms of size, weight and price, more like Canon's and Nikons 200-400/4. The "Sigmonster" 300-800/5.6 e.g. is a lens that you can't compare with the Tammy 150-600, it costs about 5 times the Tammy's price (in Europe). Past yr I had the occasion to test a Sigma 300-800. This is really a monster lens, heavy like a truck, you always need to carry a good tripod with it. I shoot my EF 500/4.5 quite often handheld, but with the Sigmonster - no chance.

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

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.

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...

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...

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 (219 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.

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.

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.
