Cicada head...

Is there a technical reason why it is 55mm and not 50mm?  Is it not possible to design a fast (i.e. f/1.2-f/1.4) lens with a double gauss design?  Is it why the 55 is a reverse-telephoto design?

... but I've been told even better - the alleged pro photog I'm ranting about in this thread told me not only that real photogs never crop, but also that of course he never needs to do it. And he was using a prime lens but almost never moved a foot! That's when I realized the guy is an idiot and I'd better double-check whatever he tells/told me :-p

Brilliant!  Misdirection at its finest!  Did you catch sight of his assistants climbing over the fence to get closer while he calls attention to himself by bloviating?

Indeed, that's the very issue why I've written this thread and am wondering if leaving more space - no matter what alleged pro photogs might say - isn't a smart idea.

I recently have done a lot of wildlife macro in awkward angles and positions (like standing waist-high in cold water with my €3000 gadget 1cm above water level), and because I missed the level the framing got to tight and the shot was lost after rotation. Btw. I've now installed the Eg-D screen for that, it's great, very unobtrusive unless I want to see it.

This was a bigger issue with lower MP cameras.  With 1, 2, or 4 MP, every pixel counted more than it does now.  I also try to leave a little space for rotations, perspective corrections.  That was one nice thing about my previous camera.  It didn't have a 100% VF, and I knew that if saw it in the VF, I'd have a little margin around the edges.  Now I have to be more careful because that margin is gone.  There have been occassional cases where I couldn't correct it as much as I'd like because I'd be making the image worse compositionally if I corrected it fully.

Well ... I returned the 16-35 yet again (didn't get third time lucky). This was the third copy I checked and didn't like it wide open - stopping down to f/8 or so was better but I can get the 17-40 if that was my main purpose.

Maybe I need to look elsewhere ... the 17mm TSE perhaps ... this just seems to go on forever.

The TS-E 17 is a great lens.  Biggest drawback is lack of AF.  If you can get around that and its cost, it's a winner!

You might want to look into a LensCoat Hoodie to replace the lens cap.  It's made of neoprene, so it'll fold/compress on itself in your pocket.  It is a bit of a pain to put back on the lens (two hands needed), but it works better for me than the original lenhood.  I have an extra small one (fits lenses with diameters of 2.75-3.25 in) that fits over my UWA lens (not the Rokinon 14mm, but the idea is the same).

it requires to change the processor too because IMO sensor + processor = film replacement - but that doesn't drive the price too much.

Ugh, why's that? Surely a processor can be designed to work with different sensors?

Anyway, for general consumer dslrs I don't see this patent going anywhere because
* changing the sensor has to be awkward in practice
* the price of a ff sensor is large, if you buy it you want to use it
* manufacturers are quite happy to sell 2 bodies (crop for reach & ff for iq)

Change the sensor for IR or UV photography rather than getting multiple cameras, perhaps...

Lenses / Re: Do you usually shoot your lenses wide open?
« on: September 30, 2013, 03:15:36 PM »
That does seem high, but I wouldn't be surprised if half of mine were taken wide open or at f/2.8 or larger (not at my computer to check it though).  I tend to use f/2.8 or larger for sports (more pictures per event due to capturing action sequences) and for single subject portraits especially under indoor available light (dim) situations.  When there are multiple subjects (f/4-f/8) or when doing a landscape or architecture shot (f/8-f/16) or macro, then the lens gets stopped down, but I tend to do these types of shots less often.

What this really means is that you have good glass.  Lower quality lenses tend to require stopping down more.

This is an emotional argument... there is no place in it for common sense :)

I think a lot of people are having a hard time getting past what EVF's used to perform like... and many have no experience with a good one. If the only EVF that I had used was the one on my SX-50, I would be sitting in the "they are crappy and nowhere near ready for the DSLR market" camp, but my experience with the VF2 EVF from Olympus tells a diferent story. It is better than the optical viewfinder was on my Olympus E-510... but I still prefer the optical viewfinder on my Canon. The thing is, I have zero expectation that optical viewfinders will improve over the years while I would be shocked if EVF's didn't.. at some point the overall package will be better.

+1.  The EVFs will get there, but I'm hoping that they can do so with minimal power.  I'd hate getting only 100-200 pictures on a battery.

The quality of the M 18-55 IS is fine.  Sharpness, contrast, etc. are pretty good.  Not as compact or as fast as the 22mm, but it works well enough outside, where there is enough light.  My biggest nit with it is the small max aperture, but it is what it is -- a very good kit lens.  Picked mine up for $150.

I am in the process of seriously considering jumping ship.  I don't have a significant investment in cameras or lenses so there are no significant legacy costs involved.  This is an advantage to me as I can look at the multiple choices with a pretty open mind.

What I truly don't understand is how photographers who DO have a significant investment in glass (and let's be honest, it does not take much to make our investment significant!!!) to consider dumping everything and switching sides.  Yikes.

That is one of the reasons I have been taking a few months to make my decision.  To me, what ever ship I jump on to and once I make my investment in good glass, that's the system I will stick with.

Do other photographers who do have significant kit jump ship often?  Right now canikon may have the "best"  but in a few years nicanon will come out with something "better" only to be followed by canikon.....  One could spend a lot of money jumping and rejumping ship when ever something "best" comes along.  I can't imagine that is cost effective.

I guess my rambling point is that just because canikon comes out with something "better" does not make my nicanon "bad".  The bottom line is:  Is my camera good enough for my purposes?

But then it is all about the gear and not the photographer.  LoL

Those that have the means use both systems and maintain both systems.

Lenses / Re: miniaturized WA lens tech, compared to 8-15L
« on: September 26, 2013, 10:24:53 AM »
Interesting -- needs a curved sensor though.

Did they seriously compare a crop of a crop from the 8-15L to a crop (sesnor resolution limited) of the new technology mated to a microscope?  Why didn't they use the microscope mated to the 8-15L?

Are you using a neck strap or a shoulder strap/holster system to carry the gear?  2 kg around the neck is a lot, but it's a lot easier with a strap system (i.e. BlackRapid).

The 70-200 II is the best choice for nature, people/pets and events, and yes, IS is almost a necessity especially if you want to use it for indoor events.  I often drop the shutter speed to 1/50 to 1/100 at 200mm to decrease the ISO.  Yes, modern cameras can get you higher ISOs, but the DR is compressed at higher ISOs and highlights are more easily blown.  Add bad lighting, and you want as much lattitude with the files as you can get.  There is a big difference between working with ISO 3200 and ISO 12800 files.  The 70-200 II also takes extenders well.  With the 1.4x, it's nearly a match against 70-300L and it is a stop faster.  With the 2x, it's a little worse than the 100-400L, which is pretty good performance.

The 70-300L is the best choice for travel.  It's compact (shorter but fatter than the 70-200L f/4 IS), which makes it easier to pack in bags (vertically), and it easier to carry when the lens is locked at 70mm.  You lose a fractional stop at the same focal lengths to the 70-200 f/4 IS, but outside, it's usually not an issue.  Servo AF is not as good as the 70-200 II's.

If I could only have 1 lens out of the group, it'd the be 70-200L II.  IQ is good and it focuses well.  Only negatives are weight and price.  I started with the 70-200 II and brought it everywhere.  Later, I picked up a used 70-300L specifically for travel (great as a zoo lens), but I still use the 70-200L II more because it is better for sports, portraits and indoor work.

I´m going to sell my 24-70 2.8II, as I don´t use it too much, and I have 3 options for the money.

Option 1)
24-105mm f/4L IS
17-40mm f/4L

Option 2)
24-105mm f/4L IS
Sigma 12-24mm II (had it on Nikon mount and it is a good lens)

Option 3)
85mm 1.2L

I´m amateur and I love my 50mm 1.2L and 135mm 2L (both are the reason for little use of 24-70) (i´m starting to use Sigma 35 1.4A).

Emotion tells me to take 85mm 1.2L. Rationality tells me to take the option 1 or 2...

What would you do?

Option 3.  You have the best mid-range zoom and you still favor the primes, so I can't see how the 24-105 will be used much at all. 

Lenses / Re: 50mm 1.2

I am asking myself the same thing. So I asked.
Not too many answers though.

Those answers are fairly representative for those that have kept the 50L.  It is true that the 50L does not outresolve the other EF 50mm AF options by a large/significant margin (see 50mm shootout article by LensRentals).  The reviews use MF/LV focusing, which does not take into account AF performance, which was a big negative of the Canon 50 f/1.4 I used.  The 50 f/1.4 AF was inconsistent wide open to about f/2.8.  It was accurate at f/2.8 but if I was using it stopped down so much, I'd opt for a 2.8 zoom.  The 50L is much more consistent, which is why people that shoot wide open a lot tend to drift toward the 50L.  It also does better on better AF Canon bodies (i.e. 5D III).  Are images softer at 100% than the 35L and 85L wide open?  Yes, but no 50mm EF optic is going to do better wide open (f/1.2 or f/1.4).  Are the colors and bokeh better?  Yes, the images look like L images and the bokeh is a bit smoother.

Is it worth it?  For most people, then answer is no.  It should not be a user's first fast L prime, and definitely not a user's first L lens.  The 24L II, 35L and 85L II are all more forgiving than the 50L.  It is not a good landscape lens (there are plenty of cheaper and sharper options).  It is not a good detail lens (not a good performer at MFD if it has been AFMA'ed at typical portrait distances).  However, it is a good portrait lens.
