On Tamron SP 150-600mm F/5-6.3 Di VC USD Lab Test Review preview (191 comments in total)
In reply to:

Henry M. Hertz: i have tested this lens against other 400+mm lenses... and there is simply no alternative in this price range.

no other tamron or sigma 400+ mm lens around 1000 euro can compete with the tamron 150-600mm at the long end. the closest is the EF 100-400mm from canon.

sure my 400mm f2.8 is better.. suprise suprise.
but there is no other 400+mm lens for ~1000 euro that can keep up with the tamron.

the EF 100-400mm canon is worse at 400mm than the tamron.
the tamron is at 450-500mm as good as my EF 100-400 copy was at 400mm.
my tamron is really really sharp at 200-300mm.
that´s why i sold my EF 100-400mm and kept the tamron.

i see this lens as direct competition to canons EF 100-400mm and it´s a great competition!!

for testchart shoots visit www.the-digital-picture.com.
compare the tamron to the canon EF 100-400mm.

the EF 100-400mm and especially the EF 300mm f4 from canon show WAY MORE CA´s then the tamron.
so i can not agree to the findings of this test concerning CA´s.

Sigma's 500/5.6 is an OK lens. I had one but it was not the sharpest either. But since this Tamron is not particularly sharp at the tele end, I wish they would try to better Sigma's efforts on a long prime. A 500/4 APS should be comparable in price to a FF 500/5.6 FF. Would also weigh much less. APS is where we need good tele lenses.

Fuzzy at the telephoto end? Why else would I want a telephoto? Can't they make them sharp at the far end and horrible at the near end where I could care less?

On Am I missing something here? article (636 comments in total)

Any enthusiast camera without a provided viewfinder leaves me cold. I can see this system as having a lot of potential. The new telephoto zoom is impressive, especially for the nature crowd. Hopefully (very) Nikon will continue to evolve this new system and if so, I will gladly part with 3K for a system I can use for general photography and the occasional walk in the several national forests not far from DC, looking for more birds to complete my life list. If Nikon does not evolve this system, at least Tamron has a new telephoto zoom I can use with a FF or APS sensor camera.

On Nikon 1 V3: a quick summary article (597 comments in total)

Right on about just waiting for a used one. Same goes for S-model Mercedes and a lot of other high priced products; no matter how good they are if only the new ones go to the well-healed look for some real bargains in a year or two. I will say that finally, some long lenses are coming out for these smaller cameras and for us birders, a welcome trend as I finally had to part with my coveted N 400/2.8 I just could not lift anymore. I just do not see buying new on these things any longer as they plummet in price so quickly.

Wish Sigma would start some nice Fuji-X lenses such as this. My X-E1 is waiting!

Does it really help for the overwhelming most of us who view our pictures on just average laptops and sharing them on the web or printing them on inkjets that cannot come close to showing all the color? Would certainly be nice if it could be appreciated and I guess in commercial work it might. Am I right?

In reply to:

grafli: They don't have to make it in Canon Mount. ;-)

Well, I see nothing to induce me to buy it. Nobody wants to develop decently fast long glass for APS, it appears. Every stop basically doubles the price and so does going from APS to FX, like boats a foot longer, and I just do not understand the problem. Surely there are more APS cameras sold than full frame by now.

In reply to:

grafli: They don't have to make it in Canon Mount. ;-)

So is this made for APS only or not? My biggest problem with APS is that there have been no APS telephotos for the mount. Even Pana has the 100-300 4/3 lens that is pretty darned good. I am really tired of hauling around full frame teles for birds and wildlife on DX cameras. Useless weight and expense.

On ISO_100 photo in dpreview review samples's photo gallery (9 comments in total)

Looks amazing to me and if anything better than my first Canon digital, the D30 I paid a ton for. The progress in sensors is astounding. It is getting to where the only real advantage of the larger sensors is to blur backgrounds.

Mr Fartleberry: You'd think Adobe would try to encourage more licensed seats rather than drive people away, eh Grumpy?

Yes, Corel's founder almost bankrupted them years back in folly and mismanagement and this is a gift from heaven for them to seize the moment and get its presence back in a big way. I am not sure if PaintShop Pro does raw picuteres or not but either way, they need to get with it. I always liked Paintshop and would gladly return.

In reply to:

stephenmelvin: Yet another camera without a viewfinder. Useless.

It is either an optical VF for me or no sale. I am not that steady and between the light and the shakes, a good picture is impossible sans a VF. Sony needs some good primes and teles for NEX. Samsung will likely give us a NX 20 and some lenses. I will wait.

Love it! Somebody is really listening and I will be one of the first to order one. These non-viewfinder things are to me absurd and I just cannot handle them. This looks to be a very upscale enthusiast camera, just perfect for me.

On Preview:sonynexc3 (13 comments in total)

Yes, as nice as they are, the lack of a viewfinder is a total zero for me. I cannot stand this current crop of LCD screen-only cameras. They are prone to movement artifacts and seeing anything in bright light is all but impossible. Would not have one at any cost.

In reply to:

jj74e: Hm...I always see stuff on their website about their Fujinon lenses being world class, and I always wonder if that's just marketing or if their lenses really were high quality at some point.

Yes, an interchangable lens camera with a real viewfinder. I think Samsung has it right in their Nx10 series but lacks lenses. A good EVF, hot shoe and lots of lenses for me. I cannot stand any of these compacts with no viewfinders. Will not touch one.

In reply to:

jmmgarza: This beautiful camera is another piece of jewelry for the rich and decadent. Precious few will see service in journalism. I would love to have one.

I will have to hope for a professional MFT camera and what few additional Leica lenses will be offered for it. Of course, some people would say that "professional" and MFT are by design, incompatible. Still, I believe I would be OK with that. Just can't justly, much less afford a M9.

Gee, what a neat picture!

All of these show as well as the art talent, the vast improvement in sensors in the past few years. DPR's gallery of the Olympus E-PL1 shows amazing high ISO response at 3200, vastly improved over my E3, which is comparable only at ISO 800.

I believe that is a stunning image--tells a lot without showing much. Sort of ethereal. That G11 must be a vast imporovement over my G5 a few years back. Of course, your technique is by far the most important thing.
