sgoldswo: It's a pity they went for speed with the wide angle, which will have made it bigger. An F2.8 that was smaller would have been far more interesting. It's time manufacturers for Mirrorless systems stopped trying to compete with DSLRs and focused on there strong points such as smaller wide angle lenses (due to the short flange back distance).

Rishi, those are lovely photos and good examples of a style of photography. I'm still not persuaded that the A7 series needs an F2 UWA lens, but that might be because of my use case (largely landscape), I accept that. However, I do feel (strongly) that there's a trend away from optically excellent slower small primes from all manufacturers (bar Leica) which I see as a negative generally. What's wrong with giving people a choice of speed or size?

Rishi, call me old fashioned, but I don't get trying for subject isolation with a 25mm lens and a F2 aperture. It's hard enough with my Nikon 24mm F1.4. I get the wider aperture for astro, but F2.8 is OK for that purpose. Also, one of my favourite 25/24mm lenses ever is the Zeiss Biogon 25mm F2.8 ZM. I marginally prefer the Leica SEM these days (because I'm a bit more 20/21 than 24/25), but slow but small UWA lenses can be really great when paired with small cameras.

photogeek: Only twice as much as their Nikon counterparts. That's progress, I guess.

@Sangster, Nikon make an optically excellent 85mm F1.8 that retails for approx $500

@adengappasami, I think you misunderstand me, I am arguing for the lens to be F2.8 or slower to keep the size down. Fast/wide aperture UWA lenses are unnecessary for most photographers and the widest aperture has become a marketing tool that is unnecessarily inflating the size of our gear.

The main reason Leica lenses are costly is the fact that they are hand made in Germany, not their size. Taking your example of Leica, the "best" lens they produce IMO is also one of the most reasonably priced, the 21mm Super-Elmar-M F3.4, which is tiny but optically excellent.

nikkornikon: I just Rented the Tamron 15-30mm 2.8VC for 10 days. I was not impressed with it as much as others. Here are the known issues.

While the front of the Tamron is weathered sealed.the back is not. A potential problem of moisture and dirty could easily rendered the Lens useless quickly. When you have the lens off.you can actually see the electronics of this lens. And A mishap of water and dirt could damage the lens.

When the lens was delivered to me...The Lens was on 15mm..but would not focused. Stayed out of focused. Not until I started moving around the lens..manually. Then it snapped into Auto Focus.

Picture Quality? I was not impressed. While yes..it took a good picture with my Nikon D810.mostly centered. the other areas where not as sharp as Granger..others have said. While I did like the VC..and it would helpful on this lens.if you were held holding it.

I would Highly Suggest to others, Rent First. Then decided. And this might be chalked up to...I might of gotten a Bad Copy!

Oh I see - but why do you think the exposed electronics have anything to do with weather sealing? They are inside the gasket when mounted. If you look at the equivalent section of the 14-24 all you have is a baffle which is hardly impermeable.

I just took a look to see if you had seen something I missed. I don't see that. Sorry. I just see a sealed lens with a gasket around the mount.

Doesn't sound like mine at all. I think you are are wrong re weather sealing too...

I've been very, very impressed with this lens since I received it. Defintely optically superior to the Nikon 14-24 in the range they overlap.

On Sony Alpha a7 II Review preview (796 comments in total)

Seems like a fair review to me and about where I'll come out when I post a write up on my blog. I'm probably more positive about the redesign than DPR, I wasn't a big fan of the original A7 series design (for example which some loved the old grip I hated it) but more critical of the RAW output being weaker than many other 35mm sensor cameras. In particular, comparisons with the D750 are warranted given the sensors in both, and its an area where the A7 falls down. All of that needs to be balanced with the introduction of stabilisation and generally faster operation of the camera.

That's ultimately pointing towards a camera that's very good, but not excellent.

On Sony Alpha a7 II Review preview (796 comments in total)
In reply to:

RubberDials: The review reads like it was written by a Nikon D750 owner and manages to skilfully bury almost all that's good about the A7ii under faint praise and exaggerated weaknesses.

What's funny is no one considering buying the A7ii is going to buy a D750 instead. A7ii buyers are trying to get away from cameras like that.

And if you want to compare them properly the D750 doesn't come off that well at all. Not surprising considering the A7ii is a higher-specced camera. It has a faster shutter, faster flash sync, twice raw buffer size, higher video bit-rate, focus peaking and IBIS as well as all the advantages of a mirrorless.

And where the D750 outperforms the A7ii at high ISO you fail to mention the contribution of the IBIS which you found conferred '2-3.3 stops of 'hand-hold-ability', so any high-ISO advantage is essentially eliminated.

Also the D750 can't shoot any wider than f1.2 either whereas the Sony has a range below f1. It can even shoot the rangefinder only Nikon 35mm f0.95. :)

Just for the people quoting terrible AF in liveview. You can stop, really. No one is buying DSLRs because they think live view focus is better than mirrorless cameras.... If it also helps the few times I've used LV with the D750 I've actually had very decent performance/results from it ;-)

armanius: Interesting that so many are intensively vested on what the review says. Almost as if they own Sony stock and are afraid that the camera won't sell well! Not getting a Gold Award is not the end of the world!

I have a Nikon Df, didn't get a gold award, or a silver. Nice camera that I enjoy using though. Awards aren't everything...

I actually own both the A7 II and the D750. As you suggest, they are in different ecological niches in the photographic world.

However, I do think many buyers would compare the two. Hands down, the DPR review is entirely fair in that regard.

The real issues with the A7 II are all associated with the RAW output and malleability. It's fair to compare the D750 in that context because it has a similar sensor, better dynamic range and produces significantly less noisy and more malleable files at higher ISOs. This is either the RAW compression or the filter array or a combination of the two. None of that means it is a poor or average camera, but it does mean it's very good, not excellent.

The only one of these lenses that's at all interesting is the 28mm. The other lenses are simply disproportionatly large.

I do wish Sony would understand that what people ask for on Internet fora isn't necessarily what the average purchaser of their equipment will ever buy.

blakevanderbilt: http://www.lensrentals.com/blog/2015/02/just-the-lenses-tamron-15-30mm-f2-8

If their method of testing out these lenses is reliable, then what they LensRental is saying is that the Tamron 15-30/2,8 is definitely better than the Canon 16-35/4L, but no where is it close to the Nikon. I'll be getting the Nikon 14-24/2,8 Thanks

bear in mind they tested them wide open, so the observations might be relevant to astrophotography but not landscape...

wassim al malak: Hello for all ,

how that lens can be compared to the NIKKOR 16-35 f4 vr ?
even i was waiting for that lens , but , i am thinking now what is the major cons of it on the 16-35 ?
may someone mention the f2.8 over the f4 , but , i think the +1 on the wide and +5 on the zoom range is worth with f4 then 15-30 f2.8 .

any suggestions ?

wassim, I'm sure DuxX has reason to say what he is saying, but in my experience the 16-35 F4 G only really gives high quality results across the frame between 20-30mm. From 16-19 it isn't really that great in the corners. I sold mine and replaced it with a 14-24 as a consequence.

In reply to:

bensherman: Is Dpreview working for Nikon by any chance? To begin with they missed the whole flare issue,then denied it and now this so called investigation (primitive compared to other review sites) that had to bring Canon in make dpreview feel good about their argument....Plain silly!

@bensherman, why do you continually post negativity and personal attacks? What exactly is wrong with benchmarking the issue against a equivalently sensor DSLR camera from another brand?

In reply to:

Stitzer23: i hope dpr can do a test on this in addition to just saying the unit they reviewed didnt have this problem. im sure they can round up a coupla d750s, point them at the sun (or just below) and tell us something. it will make for a nice blurb and complement their review. and we will have another place to argue.

Most of the cameras that even have the issue don't exhibit it in the presence of the sun, only in the presence of flashlights pointed by over anxious owners into their cameras while filming them with iPhones. Or so youtube would have you believe..

I jest of course. There is a serious point here though that not all of the cameras where the effect can even be demonstrated show the effect in real world conditions. Having said that with a wry smile to myself, if I had a camera that demonstrated this phenomena badly in real world conditions I would expect Nikon to repair it. I just don't, despite many attempts to provoke it.

nekrosoft13: waiting for announcement of Nikon D760 ;)

Suspect you may grow old and grey waiting for a D760...
As it is the D750 outperforms most other cameras in this segment other than the D810. You certainly could use it as a hobby camera (it's smaller enough) but it's also robust and functional enough for much more serious use.
