Lenses / Re: More Wide Angle Lens Speculation [CR1]
« on: May 06, 2014, 07:07:22 PM »
A 100-400 for $3000? Sounds reasonable,

28-300 F3.5-F5.6L IS for $2689..... A 100-400 F5.6 L IS of modern design and materials and greatly improved IQ over the series 1 lens could go for $3000...

Hey Guys!
One Question... I want to Upgrade my lens and actually have the EF-S 17-85mm. Would the 24-70mm f/2.8 Mark 1 be good? Is it worth the money?

I testet both lenses in image quality, build quality and others, but I think that the EF-S is a little bit sharper. Sure, the 24-70 have the lower aperture and so I can shoot better in low light, but the EF-S has image stabilisation... I dont know.

I want to use this lens for Video and Photo, but don't know if this is the best choise for me.

Please help me and give me an advice!

Sounds like you have a crop body therefore you'll lose wide end if you get the 24-70mm but gain at the long end. May or may not be a good thing depending on the type of photography you do.

For a crop body I'd suggest EFs 17-55 f2.8 IS USM - it's constant aperture and very sharp.


IS is not a good feature when shooting video because if you turn it on it both sucks back power and you can hear the IS on the soundtrack.

On a crop body the 17-55 is a good choice, but on FF don't forget about the 24-70F4... it's as sharp as the F2.8 version, a lot lighter, has IS, but is a slower lens... It's worth considering if you shoot outdoors.

It all depends on the subject...

I wanted massive detail of a site so I shot a pano using a 200mm lens.... but that's certainly the exception to the rule...

Most of the panos that I shoot are because a wide angle lens introduces too much distortion and they end up being handheld, portrait mode, two or three rows of 5 to 10 shots. If you are going handheld, you need more overlap to compensate for lack of accurate framing, so I end up using 24mm to keep the number of shots down yet avoiding that fisheye look.....

Sometimes you need to go "free form". I tried a panorama in a gazebo, and you had to be very careful to not get the center of an image in a screen or it would not stitch together.... another hint, avoid blue skies. Images stitch a lot better when there are clouds.

My favourite pano lens is the 17-55 on a crop body. The range lets you either go for a lower number of shots and less detail, or many shots and higher detail. On a FF it's the 24-70 for all the same reasons.

If you change the time per shot from 3 seconds to 5 seconds and it still locks up after the same number of shots, then it is not buffer depth problems.

Btw, have you tried saving as smaller files or on a different card?

This is all fine and dandy but doesnt explain when the 7d mark ii will be available for pre-order.  Isnt that what really matters?  ;D

I was shooting last weekend from a balcony overlooking a gymnasium.... I used 4mm static line to FIRMLY attach my tripod to the railing and another piece to act as a safety line for the camera. For some situations that is the best and most reliable safety line possible.

Stupid rumor. Sorry I cannot believe it.

C'mon man, it is the year of the lens; this might be THE lens!  :D
Still it is even more stupid than other rumors  ;)

Just because it is not a lens you want?
No just because the existing one is a very good lens.
and look at all those series 1 big whites that were replaced by even better series 2 big whites..... They were all good lenses and got replaced and nobody is complaining about it.

I'm going to go out on a limb here and suggest that the people designing lenses are a different team than those designing bodies.... What one team does does not substantially affect the other team.

Definitely a fraction of a millimetre, but that was through a microscope :)

I forgot about that... but my photo of mitochondria was to contrasty and didn't follow the rule of thirds.
Yeah.... technical photography and particularly inspection photography throw all those rules out the window....

Absolutely. Canon people may be slow but they are not idiots. If they bringing something on, they must have reasons.

I feel that Canon has enough misses to make a credible challenge to your idiot claim.  :p

Of course they have reasons.... why else would they do it.

As to if the reasons pass the test of time or if those reasons are accepted by the marketplace, that is a completely different problem.....

Definitely a fraction of a millimetre, but that was through a microscope :)

Well, those 2 lenses are targeted at different markets.

The 24-70 f/4 is targeted at the lower end of the market where IS (shooting at slow shutter speeds or have shaky hands) and wants closeup/short 'macro' operation with fairly good image quality, but not top end.

You may be interested to know that I have a friend and colleague who must be one of the most financially successful photographers in recent times - we're talking $400,000 yachts here, all genuinely from photography - and he now uses a 24-70 f4 IS.

It's inaccurate to say it's not aimed at 'top end'.

I'm tempted to say the 24-70 f2.8 II is aimed as much at very wealthy hobbyists as much as professionals who want the best possible IQ straight off the camera but I don't have any hard evidence for this, so I'd better not  ;)
Or it could be that the 24-70F4 and the 70-200F4 are targeted towards outdoors shooters who have to carry their gear a long way. Realistically, there is no IQ difference between the F4s and the F2.8s,  the trade-off is weight for speed.

Email to Lexar didn't prove to be useful.  All they did was say there weren't aware of any problems with this card and offered to replace.

Not a very useful response at all. If you can't find someone to do the recovery, the only thing I can think of is to buy an identical card and do a chip swap... but that requires some very specialized soldering/desoldering equipment and lots of skill/experience with that sort of thing.... I am surprised that Lexar can't do that....

How is it that in your treatise on software and noise reduction you didn't include the method used by Canon cameras?

Probably because he doesn't shoot JPG, which is the only situation where the method used by Canon cameras is relevant, and if you're shooting SOOC JPG images, then achiving the best IQ of which your camera is capable is certainly not your priority.

I didnt know that dark frame subtraction was limited to JPEG.
I thought (assumed) that dark frame subtraction in jpegs was done by taking a raw image, subtracting a raw dark frame, and then creating the JPEG. Wouldn't it be harder to do this with subtracting jogs?

With all the recent rumors of a mkIV, sensor/focus technology etc etc. would you pull the trigger on the 5DmkIII or continue to wait, potentially until 2015?

If you really want/need the camera, get it now. Waiting for the next model is an open-ended game. As products mature, the expected update cycles grow longer and you could be waiting for a long time... just look at the 7D, 5 years old and no solid rumours in sight... no announcements, just speculation that it MIGHT be out in time for Christmas... that means that the OPTIMISTIC view is a six year product cycle. How long are you willing to wait for a two year old 5D3 to be replaced?

Sony is like a dog chasing a car... it is amusing to watch, but it's never going to catch it..... and even if it did, what's it going to do?

I stay with Canon because I like their lenses. I stay with Canon because I like their ergonomics. I stay with Canon because I like their flashes. I stay with Canon because the camera works day in and day out with no surprises. I stay with Canon because unlike companies like Olympus and 4/3, (NOT micro 4/3), you can depend on them staying in the game for the long run. I bought into a system, not the component of the day.

You don't respond to the competition by releasing a new camera.... a new camera takes several years to put to market... Canon probably started work on the 7D2 before the launch of the 7D... The 5D5 is probably started as a project.... what comes next will be what comes next in the timeframe planned and the latest release by X or Y will not affect the schedule one bit because Canon already knows what the completion is doing.

Is there anyone here who does not think that the people at Canon know far more about what is coming down the pipes from Sony and Nikon than we do? Ever hear of industrial espionage? They have a team devoted to gathering info on the competition, while we are grasping at straws and going hyper over source-less rumours...

So like the car being chased by a dog, Canon might slow down or swerve to keep from getting a Chihuahua stuck in the tire tread, but it's going where it was planning to and the yapping dog is just noise.
