On Opinion: The myth of the upgrade path article (1454 comments in total)
In reply to:

Tord S Eriksson: Nikon have definitely put the DX lens production on idle, as they continue to produce new full-frame lenses, and CX lenses in great numbers.

And for me DX DSLR cameras are dead, or nearly so (still got one or two), but DX lenses work very well on the CX range, so I have a few DX lenses, some of which works OK on my FX camera.

In low light the FX does wonders, not possible with a DX, or CX, camera, but in good light I love to use the CX cameras, as they are tiny, have excellent DOF, and correctly treated can take almost noise-free shots. Their dynamic range isn't wonderful, but good enough in most circumstances.

For me, APS-C/DX and similar formats, are dead, while FX is thriving, and MF is the ultimate goal!

Naturally, but a 1:1 shot with a CX is not the same as doing it with a FX camera, as the crop factor comes into play here, too!

So in real life it is easier to take nice, good, macro shots with a camera with small sensor, say a 1/2", than one with a big one!

The micro-Nikkor 40 works great with my CX cameras, which then becomes a lens very comparable to the 105 on my FX camera, but its best aperture is far bigger than that you can use to get the same DOF, thus much easier to use in real life.

Bigger aperture means more light reaches the sensor, means shorter exposure speeds, and lower ISO can be used, a delightful situation!

I'd never use f/8 on my CX cameras, unless by mistake, and I loved to use f/22 on the Hasselblad!

Problem is, if you want a huge DOF, as in most macro situations, with a big sensor camera, say a 645D, you need f/22, or smaller, and then you need a hell of a lot of light (Daylight is not enough, unless the insect you're photographing is dead).

So it isn't practical for outdoor macro photography, thus cameras with small sensors, with many pixels, are far easier to work with. Like a mobile phone, but they have other disadvantages, of course.

So I use FX (excellent for landscape, and portraits), and CX (for all the rest), using lenses from 8 to 400mm focal length. Plus TCs. And spotting scopes (about 800mm, or over 2 meters equivalent focal length).

Many use their Nikon 1 cameras with flash using the optional flash as a trigger (manual mode).

CHEAW HON MING: My 2 V1s' LCD monitors are out after a year and repair costs a bomb. Luckily I can still use the EVFs. Bye-bye Nikon quality.

We have four Nikon 1 cameras (two V1, and two V2) and none have had any problems of any sort over the years.

I do know LCDs may be harmed if the cameras are stored somewhere in direct sunlight (been there, done that).

Considering the cameras originally cost about $1,000 (at full price, like I paid), I'd not be surprised if a LCD, including installation, cost around $200?!

Yes, I know, that DOF is dependent on the focal length, so a 13mm lens is always the same, no matter what camera you mount it on, but I do like the excellent DOF you get from a 13, which is the CX's equivalent to a 50 on a FX.

I wish Nikon would make a 13/1.2-1.8 (in that range), then they have superb normal for the CX range ;-) !

In reply to:

Voncreutz: Haven't seen a Viggen for a long time. Need to check this museum out next time I get back home to Sweden.

The Swedish Historical Flight flies Viggens, as well as Drakens, Lansens, and Flygande Tunnan (the Flying Barrel, the fastest fighter there was for a few years), and some older SAAB types!

In reply to:

Tord S Eriksson: The Viggen had a few problems, not least the fighter version that was much heavier than the attack version, thus the latter was more agile, and easily accelerated away from the fighter version, although the latter had a much more powerful engine.

The basic problem was using a turbofan engine in a fighter, which by default isn't the best if you want to add an afterburner: The increase in thrust is dependent of the temperature rise in the exhaust, and on a fan engine you mix cold air with the hot gases, before injecting the extra fuel in the afterburner. So the Gripen gets more thrust out of a smaller turbojet engine, and can therefore carry higher weapons load.

I've seen a lot of the attack version, not least when training for the Farnborough show, and one even crashed, just 100 meters from where I was in my truck. It crashed on take-off, when the afterburner pumped, just after the pilot had retracted the landing gear. Shells and bits flying everywhere, and the fighter, but no fire.

As a STOL fighter it was unique, and was the inspiration to Burt Rutan's all canard aircraft (beginning with the Vari-Viggen).

One other problem is that a Viggen is an excellent radar reflector, with a lot of right angles, while the Draken originally was invisible for Swedish Air Defence radars, so it was the first military plane here that had to carry transponders!

And the pilot waited till the aircraft came to a standstill, a mile or so from where I stood with my truck. Then eventually he opened the canopy with the normal electric system (quite slow), smiled, talked to the fire crew, and started the long walk back to the officers mess.

Tord S Eriksson: A bit odd that some of the shots are taken with a FX camera, and some with a DX. The FX images are so much better, while the noise from the 70D is sometimes quite annoying!

Sorry about thinking the 7D was a FX camera, but it sure is an amazing difference in resolution between the images taken with the 7D and the 70D, although both are 20MP sensors.

In reply to:

MarioV: A rather ordinary effort by Tamron.

I really wanted to like this lens, but the image quality is "ok" only if viewed at normal screen size (maximum pixel density) or reduced size.

Nothing compelling enough to make me want to upgrade from the Sigma 18-250 macro.

Sorry about my feeble Canon knowledge: both the 7D and the 70D are APS-C (Canon-style).

Would be interesting to see what you all think.

To my old eyes, the 16-300 beats the 150-600 handsomely, at 150-200!

Not being a Canon user, I thought the 7D was a FX camera. Then the difference in image quality is even more surprising, as the 70D images are not very impressive, while the 7D's are.

Sorry about that, Simon, and the rest of you folks!

To me it seems OK, and more than that, on the 7D, and nothing to special on the APS-C!

The shots taken with the 7D seems quite decent, while those taken with the 70D suffers from the restrictions of the lens & the camera.
