PowerShot / Re: Advice for non-compact versatile camera plz
« on: February 26, 2015, 07:44:31 PM »
Film Cameras I know, Digital, basically nothing helpful.

She has an inherited OM-10 (mint condition), and uses my Pentax 645 (non-mint) from time to time. A friend of her's has a powershot sx40, and she is really liking the way it fits into her hand. Thats why I mentioned the sx60.

From what I have seen here, the 5D3 is 'best in breed ', and the 70D and SL1 seem to be well respected. But it still comes back to the $'s.

I really want to help her as much as I can, she has that 'X-factor' natural ability. Pains me to admit it, but she can out-shoot me. She does awesome Street Candids, something I have never mastered.

Maybe the T3/T5 is the better option, for now.

So nobody has faith in the PowerShot series ?

Thanks again for the opinions, etc.
Is there any reason why she cannot stay with the OM-10???
Keep your OM10 as collector's object, although it still work?
Entering the digital photography universe?
See pictures on the camera and computer without film revelation and print?
Having ISO 12800 readily available?
Have autofocus available?
Having automatic lens aperture and shutter speed available?
Have live view?

My first SLR was an Olympus OM1, and I think any current Rebel model allows all kinds of adjustments and learning possible with SLR film cameras, and more.

If she ever used Pentax 645 sometime in life, should be frustrated with any small sensor camera, as SX60. On the other hand, Rebel SL1, or T5i can make spectacular images in the hand of someone who knows how to use properly.

Cameras like the SX60 is for users who do NOT wish to learn how to manually control ISO, aperture, and speed.

Macro / Re: Playing with kenko extension tubes
« on: February 23, 2015, 08:24:23 PM »
I use a set of macro extension tubes with AF and get very good results with 50mm and 100mm lens. Some people use the modest 40mm pancake with macro extension tubes, and love it.

Yes, the Macro dedicated lens make things easier, and those who will use often do not regret buying one.

EOS Bodies - For Video / Re: A Suggestion on the EOS-1D C Replacement [CR1]
« on: February 23, 2015, 02:05:26 PM »
I sincerely hope this is true! Why? So all the morons who type 5Dc instead of 5D realize they have no business changing the name of a camera for a company.
Hopefully Canon really launch a 5D Cinema. ??? So every time someone asks for advice on the next Rebel (or 70D), people will stop responding the old 5D Classic is the best inexpensive camera for all users of this planet. :-X :P

YES! Just LOVE the idea of such a model split. Canon should bring a stills optimized 5D IV for the conservative, stills-only mirrorslapper crowd. And all those yelling for 4k in every DLSR should be asked to put their wallet where their mouth is and shell out a couple 100 or 1000 more for a "video-optimized" 4k video 5D C.

You think a 5DC would only cost $100 or $1,000?
I understand what he means $200 or $2000 more for the version that records 4K video.

Nikon tried a camera "pure photography" with the ugly Nikon DF. :-[ Sales were not good, and do not think Canon will try something like that.

The question is:
A camera for photos only, will be cheaper to produce?

The answer is:
If this camera sells fewer units, its price must be high to offset weak sales.

This is a vicious cycle:
Is it expensive because it sells too little? Or sells too little because it is expensive? ::) :-X

If we consider the rumor over a 18 megapixel camera, 12 frames per second, video 4K, double CFast card slot, it fits well in a hypothetical 5D Cinema.

Although I believe that Canon can limit it to 10 photos per second, not to eat the sales of 1D series. ::)

I'm hoping for an awesome 24MP Sensor with a big DR upgrade, -3 EV focus sensitivity and many focus points like the 5DIII/1DX but more to the corner please! And a great/better ISO quality like the 6D/1dX..  4K would be nice and 1080p/60fps please...!
Your list really looks like what the target market expected a 5D Mark iii replacement.

Lenses / Re: understanding "fastness"
« on: February 23, 2015, 08:21:37 AM »
quite possible i now write total crap, but hey - thats what i think is right and if i am proofen wrong i learned something too :) so here i go ;)

its about the FOV - a 50 has a greater FOV so there is naturally more light coming through the lens (or better - to the front element).

"The 24mm f/2 lens collects light from a comparably wider field of view than the 100mm f/2. Since they’re both f/2, they both capture light at the same “speed”. So for equal shutter speeds, they should provide the same illuminance at the sensor. So in terms of exposure value, the 24mm lens will produce equivalent brightness images for any given ISO and shutter speed because it’s pulling light from more of the scene than the narrower 100mm lens, hence the identical f/number rating" -> http://petapixel.com/2014/01/29/picking-great-lens-milky-way-photography/

as it comes for faster shutter speeds its basically the same thing - a rule of thumbs i once learned (which again can be totally wrong) is to at least double your focal lenght. for a 50 that would be 1/100, for a 200 thats 1/400... every1 feel free to correct me if i am wrong :)
Let's simplify things:

Imagine two different lenses are used in F5.6 to minimize vignetting and transmission discrepancy (T stop versus F stop), with the same framework (at different distances). In this case, the lens and 50mm to 100mm will have exactly the same exposure.

You could spend time theorizing about the pupil diameter and size of the front element of the lens, but none of that changes the fact that the exhibition will be exactly the same.

That depends on a few factors:

1 Light transmission in T stops (darker than F stop).
2 Vignettes in the image corners when the lens is used wide open.
3 Different frameworks (50mm and 70mm) cause discrepancy in the camera's metering.

This set of specifications makes no sense. It has no logic one 5D Mark iii substitute have only 18 megapixel and at the same time, powerful 12 photos per second.
A true replacement could have 20 megapixel and 8 frames per second.
The difference between 18MP and 20MP is basically undetectable.
The difference in resolution between 18 and 20 megapixel is irrelavante, but for marketing looks like a downgrade.

I do not think Canon will make a competitor to A7s.

YEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEES.

I guess it is rather obvious I agree with this specification  ;D ;D ;D

That is assuming it will be a really low light and high iso beast  ;D ;D ;D
If something sounds too good to be true, then it is not true. ::) :P

Lenses / Re: EF 50 1.8 STM
« on: February 21, 2015, 06:21:46 AM »
Sorry if I missed this somewhere, but has Canon actually announced the 50mm f/1.8 STM, or is it still a rumor? This thread makes it sound like a done deal (and maybe it is), but is it possible that we might see a 50/1.4?
For now there are only rumors about a Canon 50mm F1.8 STM. Some patents have been published about 50mm F1.4 and 50mm F1.3 lens, but not all patents result in real products.

Lenses / Re: Which Lens to buy for Portraits
« on: February 20, 2015, 08:24:27 AM »
I often do individual portraits at 2.8 (with a 70D).  Are you saying that a 24-70 would be a perfect complement to my 10-18 and 85 1.8 (and I'm sticking with crop for awhile if not forever)?
Canon 24-70mm F2.8 would be a great addition to 10-18mm and 85mm. Another good option (only APS-C) is Canon 17-55mm f2.8 Image Stabilizer.
