Lenses / Re: Travel lens\es on crop body
« on: October 25, 2012, 06:57:28 PM »
A good two lens setup for travel (other than safari) is the 10-22mm lens and the 15-85mm lens. If you need anything beyond 85mm, you can always shoot in RAW and crop.

For the same reason, a good one lens setup is just the 10-22mm lens, unless you're really sure you don't need the 10-14mm range.

If you plan to take more telephoto photos than normal field of view photos, then substitute the 70-200mm f/4.0L IS lens for the 15-85.

15-85 + 70-200mm f/4.0L IS. Each are very sharp across its entire zoom range.

Could it possibly be that DxOMark is wrong???   :o

That's one possibility. Another is that the resolution may be better on the old lens even though the contrast and chromatic aberration are better on the new lens.

Lenses / Re: Should I sell my 70-200L vii for the 85mm 1.2?
« on: October 19, 2012, 02:04:47 PM »
I shoot wedding, portraits, street photography... etc. etc.  The 70-200 is great and all, I just never use it... Should I sell it and get the 85mm 1.2 and then have the 35L, 85L & 24-70mm? I'm shooting a 5DMKii & 1vHS.

Of the 35L, 24-70mm, or 70-200mm, which is the one you use for portraits now?

Maybe you would prefer the 135mm f/2.0L for portraits.

If you set your focus to the hyperfocal distance, or if you use a tilt/shift lens, you'll be able to use a lower f-stop and get more resolution. Also, I'd use the numbers for the green wavelength (0.55um). At f/5.6, that yields 60MP for 35mm.

Lenses / Re: No compact 'standard' L zoom?

The whole point of FF is that it offers better quality but only when lenses resolve that detail.

Do lenses with smaller apertures resolve less detail? Or lenses with variable apertures?

Nothing interests me less than another average zoom lens that doesn't have a constant aperture.....  :(  If you're spending that much on a body, why compromise on a crappy lens?
Why would the lack of constant aperture make a lens crappy? Are the 100-400 and 70-300L lenses crappy?

Lenses / Re: 70-300mm For my 5DM2

If you replace the 70-200mm 2.8 non-IS with the IS version of the lens ($2200 new/$1600 refurb), you won't need the 70-300.

Can you crop out the chain links? Maybe a micro-4/3 system would be a better choice for shooting through fences, because the lenses are smaller. How about a nice 24 megapixel Sony NEX-7?

The 70-300 non-L appears to have very poor image quality.

When the 5D3 downscales the raw image data from 22MP to 2MP for video, I wonder if it's throwing away information that could be used to increase the dynamic range. Removing 91% of the pixels creates bigger "virtual pixels" and that ought to add at least a few stops of dynamic range.

So if the 5D3's processor is fast enough, maybe we'll see a new firmware that improves the dynamic range of video.

I would highly recommend the IS version of the 70-200mm f/4L lens over the non-IS version. Besides having image stabilization, it's also sharper wide open.

I can understand avoiding a car or a floor number with the number 4 in it, because plenty of people are killed in cars and buildings. But when was the last time someone was killed by a camera?

I'm sure every manufacturer would produce just one model of anything if they could be confident it would sell and if they had no competition.

No, they would always be looking for ways to lower manufacturing costs that would allow them to keep the price the same or higher, in order to maximize their profits.

Lenses / What's the most you would pay for a Canon EF 500mm f/5.6L IS USM?
« on: September 05, 2012, 04:18:24 PM »
This thread got me thinking. As Don Haines mentioned, there's a huge price gap between the 400mm f/5.6L USM and longer lenses, and surely there must be a market for something in-between. I think Canon could fit a 500m f/5.6L lens into that void. So what's the most you would be willing to pay for such a lens?

Lenses / Re: A New EF 400 f/5.6L Before Photokina? [CR1]

The 400 F5.6 sells for $1350 in Canada. To get a longer Canon lens you have to be ready to shell out $9690. That's a HUGE jump in price.... and I'd be willing to bet that there is a market for something in between, like a 600 F5.6.

A 600mm f/5.6L would cost at least US$7,500. But a 500mm f/5.6L might come in under US$4,000.

Here are some photos taken with the T2i (similar sensor as the 7D) + 70-200mm f/2.8L IS II USM + 2x TC II (not III). The "original size" is pixel for pixel but cropped.
