How about a 17-40mm L zoom lens?

This one is relatively inexpensive, provides a decent zoom range for filming and you might combine it with a 70-200 f4, giving you 17-40mm, 50mm and 70-200mm focal ranges. That's not too bad in terms of overall focal length range and avoids multiple lenses covering the same focal lengths.

PowerShot / Re: Canon PowerShot G1 X II Technical Report
« on: March 31, 2014, 06:59:57 AM »
As somebody who enjoys the G1X already, I can honestly say that this Mark II looks like it will be even better all around.  Just looking at the lens specs and minimum focusing distances on that table makes me want to check my bank account.  But since I already have the first, I'll have to wait a bit until the early adopter premium drops out. 

How does your G1X compare in image quality to your 6D plus comparable lenses? I am looking forward to purchase the G1X Mark II once it comes out and am curious to learn about your experiences with the previous model.

my second image from Oman shows the dhow wharfs in the city of Sur.

Here's one I took earlier ;) Sorry, not a landscape...

What always amazes me is how those dhows (provided they are operational) appear to sit on the water due to their small draft. Again this is a shot from Sur, but taken with older equipment.

100% it is CGI.

But this isn't.

I've heard of people doing that.... I've even heard that you can do that with the reflection from the eye of a chipmunk....


It isn't new. https://www.flickr.com/search/?q=reflection%20eye

Though when you look at the angle of reflection and there is no camera there you can be pretty sure that at the least it has been retouched, the video has many shots where there should be a camera reflection and there is nothing.


At least Don's chipmunk shot is for real.

But on the other hand I can't be the only one with two EOS bodies and eight EF/EF-S lenses.
You're not!  Which is why people on this forum are not representative of the typical EOS users.
DARN! I have 2 bodies and 9 lenses.... I have to sell one off to be "normal"....
I have 2 bodies and 14 lenses... I'm ok being abnormal.   ;)
The point I'm labouring to make is that if the average EOS owner owns only 1.4 Canon lenses, then the opportunity for Canon is surely to sell them more.  This may require better promotion and/or more aggressive pricing.

I think the vast majority of dSLR owners simply don't see the need/utility.  Honestly, I think a Speedlite with bounce capability would do more to improve the 'typical' entry level dSLR user's shots than another lens, but, "I don't need to buy a flash, my camera already has one!"

The root cause for the problem you address I suspect is no more than people trying to avoid having to learn additional techniques to get better results instead of just purchasing some piece of technology, that wondrously provides improved results once the user simply clicks a single button. Using a Speedlite with bounce flash is far beyond what many consumers may want to do with their cameras. I have too often seen people just point and shoot without any kind of preparation. This is exactly why internal flash is so much wanted in entry-level DSLRs.

here are some from Oman, the first one showing the old commercial district of Muscat.

Rather than disseminating useless marketing fluff, Canon should give us the raw data, so we can see whether their claim is substantiated or not.
They could publish a costed BOM for each of their cameras too, that would be nice.

The average repair cost is at least partially providing information regarding costs for parts replacement. This is of course not the same as a BOM, but should imply that vendors like Nikon or Leica do provide rather expensive parts. Once you apply factors like production costs depending on production volume the difference to Canon becomes smaller, as both Nikon and Leica don't produce the same quantities Canon does. Of course quantities produced at Nikon are still far more than at Leica.

EOS Bodies / Re: Canon's Plans For NAB 2014 Next Month [CR1]
« on: March 20, 2014, 09:17:57 AM »
If one of those camera bodies is a Cinema EOS product, the other one might at best be a 7D Mark II? I must admit that I am highly pessimistic about this mysterious second camera being the long-rumored high-MP 1D-style camera. Perhaps it is going to be the year of the new camera body I won't invest in. :-\

Someone should make WiFi batteries for it....

I have not yet ever needed more than the two batteries I have, but it has been very close on one or two occasions. The ability to recharge them using some form of magic like WiFi would be amazing!  8)

Not exactly what I meant. I meant that instead of using the Canon Wifi adapter or wifi memory cards, one can insert a battery with built in wifi instead. That way we don't have to add the bulk of the transmitter.

Ah ok. Sorry, I misunderstood. Your idea is a very good one, I have no idea whether it is technically possible, or not, but it sounds good.

I would still like Canon to find a way for me to charge my batteries when I am on a pitch or wherever. Maybe a solar charger or something else. I know I could leave the charger and battery plugged into an outlet in the media centre or such like, but quite a few things go walkabout when you do that! It is only really for all day events, but still. I guess I could just buy a third battery.

I fear that the idea of using any low output form of providing electricity won't be enough for charging those batteries as used in the 1D-X. You did notice that the charger provided by Canon is not the same as with a 7D or 5D Mark III. Technically I don't believe it is feasible to load those batteries in a reasonable time-frame outside of using a regular power plug. A small solar charger or something like that won't do. A large array of solar panels certainly will do, but then you again will operate within normal conditions, so I don't expect anything you can carry about will do except for that extra battery.

Personally I have never had reason to use more than two batteries with my 1D-X, but perhaps I just don't shoot enough frames and especially videos per day.

Here is Rosette nebula, in the constellation Monoceros (Unicorn), just to the east of Orion. Integration of 30x210s ISO 800 light frames, 30x darks, 30x flats, and 100x bias. Total exposure time 1h 45m.



I wanted at least twice the light frames, and it seems I could probably do much better with 60x480s ISO 400, rather than ISO 800. Next time I get the chance, which may be tonight, I'm going to give it another go, and see if I can get more dim nebulosity in the periphery.


Fantastic work JRISTA and many thanks for all the information you've provided! I didn't expect such results were possible. This is great stuff.

EOS Bodies / Re: EOS 7D Replacement Mentioned Again [CR1]
« on: March 11, 2014, 03:25:14 PM »
The camera will have dual memory card slots, CF and SD. Retaining CF is a big deal and will make a lot of people happy.

How likely is this to actually happen?  The 1D and 5D lines are the only ones to have dual card slots.  Even the 6D uses just SD cards, which I can't stand due to how slow and flimsy they are.

I've got a 7D and 50D, and will probably replace the 50D with a 7D2 when it arrives.  I'm also getting tight on CF card space, and would like to buy a new 32GB CF card before a trip in a few weeks... but not if it'll be obsolete with the new 7D2.  I was really hoping we'd have a more concrete announcement by now.

Given than the 6D now uses SD cards, how likely is it that the 7D2 will use CF cards?  Will they abandon the 7D1 users and cater to those upgrading from consumer bodies by using SD cards?  I'm sure speed is also a consideration, since that will be a big selling point of the 7D2 over the 70D or 6D.

The choice between using CF or SD cards will be determined not only by how much this rumored camera will be positioned for professional users, but the maturity of SD cards as determined by Canon. If this camera will indeed get CF and SD card slots, this will make it comparable to 5D Mark III, which I don't expect it will be. So in my opinion this CR1 rumor is not likely to become a reality, because as you stated the 6D uses just SD cards, so the 7D will likely share that trait, if it is considered as being somewhat restricted in comparison to a 5D Mark III. This logic may not be found appealing by many, but Canon may nevertheless use such kind of a distinction in card support.

Lenses / Re: Glass is the most important?

Why don't you experiment with different subjects to take photos of? You can systematically acquire new techniques instead of new gear. I tend to experiment a lot seeking to optimize my technique like that. GAS helps in bringing in new gear to play with, but that shouldn't imply that you can't do new things with your old gear.

Actually you can look at the specs for the new Powershot G1 X Mark II sensor as an example.

According to specs it is relatively low MP (12-13 MPs depending on shooting format) and it is supposed to be good in low light. I have actually pre-ordered one of these as it also offers a very nice focal-length range. According to Canon this Powershot will offer good reaction speed and what is praised in Canon ads like it will be fully optimized no-nonsense controls. Of course this camera doesn't really qualify as a rumor. We only need to wait some time until it arrives in shops and of course in reviews, too, for those not wanting to pay for something they don't know how it will really perform.

Lenses / Re: Canon 50mm f1.2L lens focus shift
« on: January 14, 2014, 10:29:48 AM »
One of the problems with the 7D + 50mm f1.2 setup is that this camera's AF is not very well suited for this lens. When I first purchased the 50mm f1.2 it took me a significant time to learn how to properly focus this lens. I eventually learned the technique, but as soon as I switched to 1D-X and 5D Mark III, I could lay that technique to rest as with those cameras the lens focuses perfectly. This is a technical difference you cannot really make up for.

With the 1D-X acquiring focus also appears to be a bit more snappy, because it provides more power to the lens, which has an effect with large aperture lenses (the 85mm f1.2 in particular).

Regarding technique you can try two things:
1) Allow the camera more time to achieve focus. Don't shoot or avoid fast-moving, erratic moving subjects.
2) Experiment with manual focus. You might be surprised.
