For such a specific application you might get some data from canon. I suspect you will have do some tests to determine sensor performance and raw output. You may well need to read the raw files directly, rather than using a raw converter. Thinking of raw converters they all make the conversions differently (I'm talking algorithms for those that like long technical sounding words  ::) ), so you may need to talk to them as well. I'mwondering what your ttrying to record that needs so much data?

If your real only interested in landscape, what other people think and WIFI but  things like cost weight and all sorts of other things don't matter then go medium format.

Ps let me know if canon reply to you.

EOS Bodies / Re: Canon to Make a Big Splash at Photokina? [CR2]

Regarding the 7D II, although I'd enjoy seeing IQ improvements and the new information that there is new sensor tech in it makes that more plausible than before, it was NEVER the driving consideration for me.  The features that most interest me are an improved AF (especially with Server accuracy and speed) and improved speed.  Although the current 7D's 8fps is nothing to sneeze at, getting 10 (or the sometimes hinted 12) per second would be a bonus.  But it's a killer AF that is what MOST intrigues me--something like the superb 61 point system derived from the 1DX/5D III.

If I was in the market for a 7D Mk2 (and I'm not) an improved AF with improved higher ISO performance would be of interest.

It will be interesting to see if there is something new about the sensor tech that comes out, if that's what is going to happen. Lets hope its not just a loads of mega pixies video camera.  ;D

Just wondering, how do you find Servo AF accuracy (and speed) with the Tamron?

I may be a bit slower.  There were some AI Servo problems with early samples (achieving focus, not maintaining focus) that have apparently been addressed by firmware updates in later samples.  Compared to the 100-400 I do not see any evidence of decreased accuracy.  The 100-400 is no gem in that regard, in my experience.



Quite right.  I use the 100-400 and the 7D and AF is generally good, but not always.  I'm glad to hear they've addressed the AF accuracy issue as it's the one thing that worried me regarding the Tamron as a possible addition to my kit. :)  Thanks for taking the time to answer!

The bad press that the 100-400 gets puzzles me a bit. I've had one for years First I used it on a 30D now its on a 1Dx. While I'd be the last to say its one of the best, I do own a 300 F2.8, I still find I can get good images with it and use it a fair bit. The top images was taken years 8(?) ago with the 30D the lower one last weekend with the 1Dx. The lens has been used and abused including being dropped on occasion and sometimes got quite wet.

I will be quite happy to consider a 100-400 MK2 if it should appear. Until then the Mk1 will be in use.

Lenses / Re: 300mm f/2.8 L IS II - what do you use it for?
« on: July 30, 2014, 01:28:53 PM »
In a slightly more sensible vein than the last post.

About 50% of my images. Checking with LR I find that the 300 with the converters is by far my most used lens.

But I do wild life so its not much of a surprise. A bit of motor sport. Even the odd still life. And the occasional Macro.

All in all its a pretty special lens, for me anyway.

I didn't try a macro yet with that lens. Did you use an extension tube or extender for the second and third photo? I presume that those are made on tripod

both those shots were hand held with a 2x extender. The flower was processed to have grain, originally it was very smooth.

it's very easy to hand hold and compact for the 600 mm length.  I often use it with a tripod, but that's mainly for ease of use as the IS is very effective.

My office gets pretty hot at times so I need to leave my fan on.  If I've got papers on my desk, they can get blown off.  Fortunately, the 300mm f/2.8 Mk II has enough weight that I can have the fan on at high speed and with this lens placed just right, the paper sits perfectly still.  I think the IS is key to that functionality. 

When I'm not using it to hold down paper, it makes a great door stop, allowing a good cross breeze though the office.  I can honestly say my life has been considerably better since getting this lens.

  :)   Exactly what I thought of when I saw the title.

Thanks for the insight Omni.  I'll hold off on the teleconverter.

Don't be too quick to discount the tele converters.

They can be pretty good these days. Try one with the lenses you're thinking of buying. They can add a lot of versatility. But they depend on the camera and the lens combination. Like anything photographic there is a trade off to make your mind up about.

I'm very please with my converters. They get used with my 300 a lot and my 70 - 200 a bit.

Here is a shot taken with the 70-200 and x2 converter. If it was slow focusing I would never have got this shot, it was there for less than 1/2 sec.

Here's hoping they have a much simplified mode dial on the 7D2....

Could I suggest the following layout.....

Add C1-5, and I'd be happy. :Dķ
Even better!

Wow....that would make it essentially useless for fast-moving subjects in fast-changing light.

M mode with Auto ISO is great for fast-moving subjects in fast-changing light!  You pick the shutter speed to freeze or show motion, the aperture to give you the DoF you need, and the camera picks ISO for a metered exposure.  On the 1D X, you can bias the metered exposure by setting EC.

that's my most used mode these days. Works a treat and I just adjust aperture and speed as needed.

Hi Again Henry.

If you hadn't mentioned your age we wouldn't know how old you are. Anyway it has nothing to do with the advice I have given, and I didn't notice anyone else taking any notice. Apart from you that is  ;D

But you do seem to be missing the point of my post. I was saying it is quite easy to do the AFMA with nothing other than the camera and the lens. You don't need any fancy software, and you don't need to send them back to Canon. Unless you run out of adjustment, and I have no idea how often that happens.

If you do it yourself you will learn about your camera and lens as well as saving some money. Give it a try its quite easy.

Hi Henry

You should be able to PP decent image files in DPP.  Some prefer it to LR,  but of course it is much much more than just a raw converter.

Your images are interesting but not the sort of thing that is best for checking lens or camera. A vertical target and an inclined ruler will do fine for setting up auto focus. My favourite way is to photograph a single flower on the lawn looking down at about 45 degrees.  You can soon see if the grass either side is in focus and so see if you are front or rear focusing. I have recan but never use it now.

If you check focus and set it right but still don't get images you think are sharp enough you should try a tripod and or a bean bag.

If you still can'tget Iimages you like talk to an experienced photographer.  There are lots of us about. And most are quite willing to help a youngster understand and progress. Who knows they might even say the problem is your lens. That's not likely but it certainly could be.

I hope this helps your development as a photographer and gives you no offence. As you do seem rather dismissive of the help offered so far.

Software & Accessories / Re: Lightroom vs. Capture One
« on: July 22, 2014, 06:38:26 PM »
I use light room for most of my work. 99% of the time it's fine. BUT every time I want to get the best out of an image I go straight to capture 1. I like the images it produces and have been using it for about 2 years now.

DPR also produces better images than lightroom IMHO and of course it's free  ;)

BUT lightroom is a great database for photos,  with an in built raw converter. I find I'm using plugins more and more with lightroom, but for those few special images, for me, it's capture 1 followed by photoshop every time.

You can't beat good skills and good gear.  :P  Unless you have talent as well.  :-[

Time can be a factor, but gear is not immaterial. If I wanted to get a shot of bears, I'd much rather have a 1DX/5D III and a 600/4 + 2x TC, or a 7D and 600/4, than anything else.

Think I'd go for a helicopter first myself  ;D

You wimps!   ;D

taken at 140mm these are full frame, there was nothing between us and him, just talking quietly so as not to scare him, as he hadn't spotted us until he looked up.

I've put in one cropped cos I like the look in his eye. I think he was a bit pi$$ed that some one got in his way.   8)
