Alphoid: Wow! For just $600, I'll be able to get ugly photos all the way from 16mm up to 300mm for months, maybe even years, until the lens breaks!

Thanks, Tamron!

I see people post mind blowing images taken with $300 P&S cameras. Judging by your comment, your problem isn't the equipment.

On Panasonic Lumix DMC-GH4: a quick summary article (471 comments in total)

I doubt that it can record 200 Mbps without the additional DMW-YAGH interface unit with the 4 raid card slots - $$$. So it isn't really a feature included with the camera. It is like saying that my DSLR has a flash guide number of 54 when I buy and attach an additional external flash not included with the camera.
Perhaps if they had actually added a second card slot to the camera?

The EXIF data has been scrubbed from the samples at

but appears to be a Canon 60D.

In reply to:

mrc4nl: as a m43 user a rectininear 10mm is great, the question for me is which mount should i choose.

a "native" m43 mount may yield better results (because a adapter will introduce small misalignments)

Or i choose i Nikon mount, so i can use it on a nikon body, but also on a speedbooster gaining one stop and perhaps even better sharpness.

@ Peksu - Yes, Speedbooster WILL work with APS-C lenses on M43 full sensor coverage. I checked with Metabones.

@ Francis - Yes, by compressing the image coming into the Speedbooster it also increases sharpness and MTF.

This info is easily available if you actually want to look for it. Or you can be ignorant and post dumb comments.

Interesting that this arrangement is also much closer to the human eye with semi random arrangement and sizes of sites. Should reduce moire.

Ha ha, I guess the "gaudi wood retrofitted uglified Sony camera for some insane price" could not continue forever.

Sarge_: As a professional photographer who shoots a lot of architecture and landscapes, I wish someone would come out with something affordable in medium format. No pricing, but I'm guessing this is not the product I'm wishing for...

It is called Giga Pan or Autopano. Under $1,000 and virtually unlimited resolution. Unless your buildings are running away on you.

On Nikon Df Review preview (1617 comments in total)

I have never touched this camera and never plan to, but it does seem arrogant for Nikon to lower the specs on a camera and give it a retro look and then charge a fortune for it. No wonder it isn't selling well. It really seems like it wants to be one of those "look at me, I have too much money" kind of pompous cameras. I mean why else wouldn't you get a D800.

SteveNunez: Considering the worldwide growth of m4/3, surprised they don't offer this len for that system- it would easily be the largest focal length available and would surely be popular with m4/3 shooters....ashame.

@ Jogger - "it wasn't designed for contrast detect AF" ???? What are you talking about??? Are you saying that this won't work with the Canon 70D or any other DSLR in live view mode?
MTF charts are still around 10 to 30 lpmm and the new digital sensors are around 250 lpmm. Who designs lenses specifically for contrast detect AF?

In reply to:

koolbreez: If the IQ is up to par, and the VC works good, this will make a nice addition connected to my Nikon D7100, set on the 16mp 1.3 crop setting, essentially making it a 300mm-1200mm at F5-6.3 and then in focus at 2.7meters away, decent macro shooting comes to mind at a good working distance. Now that is a respectable "reach out and grab it" wildlife optic. It even makes it more enticing at 1680mm at F8 with a 1.4 tele-converter attached, although manual focusing hand held might have to be completely reconsidered depending on the VC quality...hehehe.

Never figured out why anyone would set their camera to crop mode. Why not just crop in post? Exact same IQ and focal length translation but you get more image around the perimeter in case you need it. Kind of a really dumb feature.

In reply to:

Leandros S: Yeah, well, we need a Pentax mount version of this lens. Whether it be from Tamron or Pentax, same difference really.

@ Tonio - I think brendon means that if Pentax made a lens with the same specs it would be more expensive.

In reply to:

dlkeller: B&H doesn't list VC as one of the features in the Sony version. If this is true Sony A mount users are being screwed again. Hope it isn't true as it looks like a lens I would buy--but not if VC is left of my version.

I agree. I have the A77 and I have to pay the same price for every lens if I want the most recent optics even though I don't get the VC in the lens. In general Optically Stabilised lenses are much more than the non-OS. It is implied that this cost it most due to the VC and the VC technology. So if the Sony version doesn't include any of this then why is it the same price. I agree, we are kind of getting screwed. At least I have added a custom edited EXIF AF confirm chip to my manual focus lenses for about $20 and they become image stabilized. Something Canon and Nikon users can't do. So you got to take the good with the bad.

In reply to:

hires: $1069. This thing is going to get wriiten up in no time. The low price could mean that it can't stand up against a Canon 400L. Maybe it will put a little pressure on Canon to stabilize the 400 5.6L.

Looks like it kicks the Canon L butt even without the VC turned on here:

In reply to:

Photowyzard: If the optics and IQ are as good as I expect, this will be the "next" lens in everyones kit. I can hardly wait to see what type of image this Tamron delivers for $1200.

Answer to your question is Yes. Not only does it "trump" it, but it destroys it in every way for less money PLUS ZOOM!

Direct link | Posted on Jan 12, 2014 at 15:06 UTC

Looks like this is even better than the Canon 400mm f5.6 L USM at the same 400mm f5.6

AND it is a zoom that goes all the way from 150 to 600 at the same time as having higher IQ.

http://camahoy.com/

Wow, and only $1069

AF speed also seems to be much faster than the Sigma 150-500 HSM.

Love to see this DxO Marked. Glad Sigma and Tamron are forcing Canon and Nikon to get off their ASSets

On Homemade rig captures extreme macro shots of snowflakes article (186 comments in total)
In reply to:

Vitruvius: Very inspiring. Not sure how to "zoom in" a prime lens but will try it some time. I tested the lens reversing idea once and found that the wider the focal length the higher the magnification. So with my 16-50mm reversed at 16mm I got a single letter on a coin full frame (APS-C). And that was with the front of the lens right tight to the camera. Now I am inspired to build a marco tube. Thanks! Awesome. Also proves you don't need the best equipment.

Ahhh! I didn't think about the camera had a zoom lens as well. Thanks for clarifying.

Same story from Sigma over and over. Must have replaced some of their software staff with optical designers because they sure are good optically for the price.

Holy Crap! I am actually really impressed with how well the RX1 does against the others at "only" 24 MP against the two with 33% more resolution. Check out the lock of hair. Wow.

Is that a superior lens resolution issue?
