yahoo2u: If Nikon go APSC/FF mirrorless with an adapter for the DX/FX lenses, i'm in.

This weould be a weak compromise. Nikon mount used lots of mechanical coupling in the past. Nikon has only three options here:

1) The adapter only workes with the latest lenses (all electronic focus & aperture). Lots of lenses have mechanical aperture, but no aperture ring. Such lenses would not even work in manual mode.
2) Once again put mechanical control for aperture (and for 'pro bodies' probably also AF) into the body. Making the body more expensive, heavier, more complex and bigger.
3) Put all that into the adapter, making the adapter heavy, big, complex and expensive.

All 3 options are bad.

PieterB: The main problem with Canon's and Nikon's mirrorless offering is that they don't want to cannibalise their d-slr line-up and thus making cameras that are blown out of the water by other mirrorless camera manufacturers.
This may be a successful short-time strategy but in the long run, people will switch to another brand.

Yes, this is a common management mistake. Steve Jobs once said, if you do not cannibalize yourself, someone else will.

scotthunter: It's sad how people these days put convenience above image quality. Who cares about pixel count, shadow detail and dynamic range if all people want to do is upload a picture of their dog on Instagram with a filter so that their friends can like it on their 4" phone screen.

I have use a Canon G7X Mkii - slightly less pocket friendly but it's a brilliant little camera and cost me £200 less than my phone. I can print huge canvas photos of the images I take with it, and even mount it on a triod to take pictures of the stars. In almost every respect, a dedicated camera is a better tool for the job.

For many people an iPhone /Samsung S /Xperia etc. is actually the best camera they ever had.
During film days most cameras were not SLRs or enthusiast compacts. They were single use cameras or simple compact cameras that were not much better than single use cameras. Often with a f/10-ish fixed focus lens, maybe some primitive zone focus. Many did not have any sort of metering, maybe two or three exposure settings ("sun","cloud", "shadow") and a flash (without any control beyond on/off). They had viewfinders that only gave a vague impression of what will be on the pic.
Most people never cared. They were only interested in small prints and the machine in the lab did its best to auto fix wrong exposure and wrong colors.

SharkManEXR: This lens also does NOT work with anything before the d3300, it may only work with the d3300 with a firmware update but it is not stated on the firmware page as it only lists the 18-55mm AF-P lens.

buyer beware! no idea why Nikon did this.

Conrad... Absolutely.... I am going to upgrade from D800 to D3300 to get this lens... ;)

trungtran: When will manufacturers make budget telephoto primes. Simpler than zooms to build and better IQ and they can even charge the same price.

A $400 "budget" 100/5.6? No. There are several 90/100/105 f/2.8 macro lenses in that price range. 85/1.8 also is not that expensive. F/5.6 would be pointless.
Even a 200 should be much faster than f/5.6. A Tomron or Sigma 70-200/2.8 is not that expensive, at least if you look at older versions w/o stabilization. At that lens speed you can live without it, especially if you have to use fast shutter speeds anyway (sports).

In reply to:

digiart: Nikon is braking the compatibility of it's DSLR gear time after time. First they dropped the built-in AF motor in the D3XXX and D5XXX range. Then, camera firmware updates stopped third party batteries from working. Now, they release AF-P lenses that don't work with almost all of Nikon bodies, denying it's loyal customers the benefits of AF-P. I feel this is like an abusive relationship. So infuriating! I don't think I will buy Nikon gear again.

I bet they can't make AF-P lenses to work on most of the camera bodies because it probably draws more power than what the cameras can deliver. If that's the case, it was bad decision to design without accounting for use of different type of AF motor.

Really a power limitation? Does it take less power to focus a 70-200/2.8 etc? These things are HUGE!

In reply to:

MShot: If they make a really great mirrorless camera, what do they say to their DSLR customers? We were only kidding?

There is a big difference: 4/3 was a weak compromise for an SLR system since the beginning. The viewfinders were small, dark and 'tunnel like'.The only option to improve was to go mirrorless. The original 4/3 SLRs were not very popular and competetion (Canon, Nikon, etc.) was tough. So there was nothing to lose.

For Nikon it is very different.
APS-C and (even better) FF work very well for an SLR. There is no reason Nikon could not make SLRs and mirrorless cameras (or even some 'hybrid') with F-mount. Nikon would face tough competetion in the mirrorless world. The large lens collection they have tody would be an asset. But only if they work out of the box. Adapters tend to be expensive and they are usually a weak compromise. So F-mount right on the camera. Who wants another system that only has a 5.6ish kitt zoom, a consumer 5.6ish telezoom and the ultrawide/macro/portrait/fast tele 'next year'.

In reply to:

Zoron: Good price....competitive product that all the FF owners can upgrade to.

All of MFT/APS-C/FF were 'hot' when they arrived:

APS-C was the first practical dSLR. Larger sensors were too expensive. Smaller sensors would make the viewfindet too small. One of the reasons why the original (non micro) four thirds failed were 'dark tunnel' viewfinders. APS-C could use many old lenses from the analog aera with an acceptable crop factor.

When FF CaNikons arrived, many people -millions- had FF lenses for these. Remember, 36x24 had dominated the photography market for decades. It made sense to continue that format in the digital age. Get rid of the 'APS-C compromise'.

MFT was also 'hot' because it started the mirrorless age. The market was waiting for mirrorless cameras for years and MFT was the first to deliver.
Yes, I think this camera will deliver better quality than FF. Somewhat, at least. But there are only 3 lenses available. Nothing really fast. Old MF ("analog") MF gear could only be used with compromises (crop factor, manual focus).

Bryan Costin: It's not so different from how snapshots were taken pre-digital. Finish a roll of film, send it off to the lab to get it developed and printed, maybe with a note for the darkroom tech describing any special requests. And when you got back the prints it could be a bit of a thrill seeing how your photos came out.

This seems prohibitively expensive, particularly since they've apparently automated the retouching process. I guess they'll find out if there are enough people with spare money who find this appealing.

Its very different. I still use film every now and then. My camera lets me controll exposure and change lenses. I get the entire film from the lab after processing. I can decide what is good and fail for myself. If I don't like the way the lab prints a picture, I still have the negative that can be scanned, printed in a different way etc.

In reply to:

nokinonacynos: Looks like an amazing cam. However, I think MFT will continue to struggle. Once the cam is not pocketable, size becomes less of an advantage. People are realizing that a certain size is required for comfort and ergonomics. With a Pro lens, the package is similar to APC. So no advantage. In fact, the 25mm 1.2 is bigger, heavier and much more expensive than a 35mm f/2 for APC let alone a 50mm f/1.8 for FF.

This camera will have to sell on inherent qualities rather than size and weight.

I don't think we will see 1'' sensors in phones in the near future. Of course it is possible, the Nokia 808 had a sensor that was even a little larger. But marketting dicates all flagship phones have to be thin. Thin is more important than everything else.
Some Sony phones have 1/2.33'' - the same as cheap entry level compact cameras. That's big in the smartphone world. Expensive phones like iPhone 7 have even smaller sensors. Even if the IQ was there smartphones would not be good not enough enthusiasts or pros for many reasons : No viewfinder, no controls other than touchschreen, no long focal lengths, weak LED instead of a xenon flash, af and shutter lag disappoints even when compared with entry level slrs...

I think there is a market for mft. It is the smallest system that has IQ better than phones/simple compacts (Pentax Q doesn't) and a reasonable lens selection (Nikon 1 doesn't, nx-mini doesn't).

Why are all these instant cameras so primitive? Zone focus? f/12.7? Come on!

moawkwrd: Who is buying these lenses without VR? People who don't know better, complain about their terrible photos and then end up buying the VR version or more expensive lenses anyway. Cha-ching for Nikon. Why can't big companies NOT be complete douchebags?

Its easily possible to get decent handheld shots at 1/500s or 1/1000s handheld at 6.3 in daylight.
For sports you need fast shutter speeds anyway. Yes, even soccer mom needs fast shutter speeds. VR would not help much.

VR may be a substitute for a tripod or monopod, but to get faster shutter speeds in low light you need a faster lens (much more expensive).

Link | Posted on Aug 17, 2016 at 11:42 UTC

70-300/4.5-6.3 ??? Do we really need even slower consumer zooms? Come on, 6.3 is for cheap third party travel zooms only. Does the AF even work at 6.3 on an entry level body?
And no, VR does not compensate for any moving subject.

Regardless of the quality of the lens, Samyang should probably rethink what blockbuster means.

Using the lens in winter voids warranty.

On article Special K? Pentax K-1 Review (2674 comments in total)
In reply to:

zakaria: fair enough review. pentax knows what is its weak area/AF/.
for pentaxians we know that k1 is not d5 it is d810 like.
do you think d 810 is for action photography.
who said a 36 mp full camera should be a sports camera!!
i accept k1 as it is for.

I ocasionally use a D800 at running events with a Sigma 70-200/2.8 HSM. No problems to get sharp pictures - even fast elite runners. I don't have a D810, but I don't think it is worse.
If you are a fulltime professional sports photographer, you would prefer D5/D500 (or whatever Canon). But if you want something high quality, 'general purpose' including some action, D800/D810 will do fine.

Link | Posted on Jul 6, 2016 at 07:13 UTC

The original was probably around f/17 (22 times slower than the later f/3.6 Petzval lens according to several sources).
This lens is five stops faster! Even with modern materials etc. I don't think it is possible boost the original design to f/2.9.
Maybe the pictures look similar, but most likely it is a completely new design that has nothing to do with the historic original.

In reply to:

dlinney: Having taught DSLR photography to beginners for many years let me suggest a profile for the typical buyer of this camera: he/she will shoot JPEG, will shoot in full auto-mode and will use the output pictures as is with little or no post-processing. Concepts such as shooting RAW or lifting shadows in PP are no yet in their vocabulary. They will assume the AF system works without needing to know the different AF modes. They will read an article on "20 ways to improve your photography" but give up when it simply confuses them (it took me two full days of a hands-on course to teach what such articles expect to cover in 2 pages). Enthusiasts will tell them to shoot RAW and shoot in manual mode and their photography will deteriorate and they will revert to full auto.

So, evaluate this camera against this scenario. Comments about an outdated sesnsor etc. are simply irrelevant: does it produce good Jpegs? End of story.

@dlinney: Sorry, did not want to attack you. I had to do with students (arts, design, etc. and creative hobbyists) who picked up cameras like the D40 or 350D happily because they were affordable, but had decent image quality and features and manual options. I was in the same situation. We took photography very seriously, we just did not have much money. I don't know if that is a large market, but many of them buy better gear later (I bought D90 and D800, later).

Entry level DSLRs are still a good tool to learn, but the 1300D does not offer anything new to these customers. Same results with a 1200D on fire sale.
I think the family/casual shooter you describe should get entry level mirrorless instead. More similat to smartphones, compact cameras, camcorders.

Gesture: 95 percent viewfinder coverage. Actually, I'm impressed.

But a sub-standard viewfinder is still better than no viewfinder at all (entry level mirrorless).

Very biased. Why do you think everyone who cannot spend lots of money on a camera does not know basics and does not want to learn?

My first DSLR was a Nikon D40, probably the most basic DSLR ever made.

I used aperture priority most of the time, sometimes shutter prio or manual. Beyond the kitt lens , I bought a 50/1.8 and a (used, old) 90/2.8 macro. Very usefull even tough both were manual focus only with the D40. I installed a split image focusing screen that was available on eBay.

I took many, many pictures with it. Never used auto modes.

Yes, I did know photography basics, I had used manuel film cameras before. I was just happy they finally made DSLRs that did not cost thousends.
