you should also have a good look at the new version tokina 11-16mm f2.8

Personally i'd go with this as having a fast aperture wide angle can be very usefull for things other than landscapes

I think on a 70D i would go with
tokina 11-16 f2.8 for wide
sigma 18-35 f1.8 for normal

wait for the new 50mm with is from canon or the new sigma 50mm

and you already have good glass at the longer end

Hi

I am considering buying a high MP body for landscapes. Right now Canon does not a high MP body (5DM3 is 22 MP), not quite high MP.

As i see it, there are 2 high MP 35mm bodies - Nikon D800 and Sony alpha A7R. I think both use the same sensory though there is a difference in cost - the nikon is 3300 vs 2300 for the Sony.

I think it will be easier to attach a canon lens (such as the 17mm T/S) to the Alpha as well as attach the Nikon 14-24 to the Alpha (is this true) than the Canon 17mm T/S to the Nikon. Is this true?

Other lens to consider? With the Nikon 14-24 is there any reason to use the Canon 14mm?

Other thoughts are welcome.

Thanks

i think the a7r and the canon 17mm TSE would be a pretty hard combo to beat by anything at the moment

For some reason I was expecting to see Osprey aircraft when I clicked on this thread . Nice shots of non mechanical osprey though!

I did one test: the brick wall! Trinity College's Tudor brick chimney. The 70D and the 5DIII were on a tripod for this test, both at f/8 and 600mm with the Tamron. From top to bottom; 70D scaled down to 1200x800; 5DIII scaled down to 1200x800; 100% crop from centre of the full-sized 70D; very bottom, the centre from the full-sized 5DIII upscaled by 1.5x. If you crop the centre 200x200 the 70D is slightly better, but the image is too small anyway to be of any use.

Both lenses were AFMAd 3xtimes, Dilbert.

I think the 5DIII image is better. But, it's only one example under one set of conditions.

Canon made a deal with Tamron to release the specs. for the Canon lenses, in turn Tamron had to release the first batch of lenses only with Canon mounts.

Where did you hear this? That makes no sense given that they are competitors. 3rd parties release Canon/Nikon mounts first because of sales volume (compared to Sony, for example), not because of a deal with the OEM.

I can't speak for their stock, but the last several Sony products I've bought have been junk. Two of them died on days 91 and 93 of their 90-day warranty... They Sony of my childhood seems to no longer exist.

Click to expand...

A 90 days warranty seems quite short?

In the EU those same Sony products have a 2 year warranty, and are required to do so by law.

I am not aware of any evidence to suggest that Sony products consistently fail within their warranty period.

But I bet there are lots of similar stories claiming Sony products fail on day 731... (or 732 if there was a leap year )

Forgot in my haste to mention that you guys posted some nice pictures here. The beautiful picture of 100 is something that would be way cool to take. I have even dreamed about trying for a hand held megapixelish stacked photo.. Don't know if that is possible, but will be great fun to test anyway.

I remember the image. This is the camera and lens an alligator carried off (in Florida?) which was later recovered. Someone motivated to get it all correct can look it up to get the details right. Perhaps the poster wanted people to know that a body like the advertised unit made it through something traumatic...and I don't know to which body that toothy one took a shine.

However, "making it through" might be too optimistic by half.

I was on Cocoa Beach two years ago with a shooting buddy, (shoots Nikon) We were taking some shots of seagulls taking to flight. I was using my 7D paired to my 70-200 lens. The friend was using his new $2100 Nikcor lens. We were set to shoot the flock, as the took to air, they lightened their load and crapped on us. My Canon lens got hit, but the friends lens was covered on the outer element. I removed my filter and cleaned it and went back to shooting. The friend had a real problem, seems the high acid in the gull crap ate away the outer coating on the lens. But, only in spots. After got it back to the motel, and took some photos it was plain to see the effect of the coating on the outer element. Buy either a UV filter, or clear glass in filter ring, and cover your outer element. You can remove it when shooting with a CP filter to prevent possible vignetting. I did get tree sap on my EF 100mm f2.8L IS USM Macro it was on the outer element, but came off quickly, and cleanly. I was shooting a bug in a orange tree in the backyard. Thank goodness for Zeiss wipes.

Since my last post, I found a guy on another forum who specializes in only lens repair. Since my lens is actually not of "L" quality, but just a EF lens, he suggested when the lens does fail, just toss it. Why, the parts are not available from Canon, and he would have to research where to get the parts, the parts would be from a used lens. The cost of all this would more than pay for a new lens. So, I bought a new Tamron SP 24-70mm f2.8 VC USM lens. Great lens, fast focus, and about twice or more the weight and much faster. It keeps up with the focus speed of the 7D.

In my experince, when you extend an olive branch to someone with a huge chip on their shoulder, they tend to think you plan to hit them over the head with the branch and they often respond aggressively.

It makes sense to have compact FE UWA lens instead of this.

My G.A.S doesn't call out for this lens.

Click to expand...

+1 ... the whole concept of, a7/a7R is its compactness, but the size of this lens (which is just 1 inch shorter than the 70-200 f/2.8 L IS II) defeats that purpose.

My next trip to China is 2nd week of March. My co-workers and I are planning to take a trip to Yangshuo, China. Having a UWA lens for my A7r is a MUST, plus 3-4 spare batteries ;D

cool if you go to yangshou you have to go to the big performance on the river cant remember the name but its a major attraction there its at night i took the 70-200 2.8 and had it on a tripod with 5Dmk2 it was pretty good although could have done with a bit more reach a sigma 120-300 2.8 would be the perfect weapon for shooting that.

where else are you going in china, i live here now and, i'm always in and out of shanghai and dalian if you are up my way let me know and we can grab a beer or ten

or take you to photography heaven in shanghai
with absolutely everything and prices basically the same as digital rev

Thanks wickidwombat, That one is on my list

We have suppliers in Dongguan & Shenzen areas. I usually land in HongKong Airport and take Ferry to Humen & Fuyang. Although I'm more like a red wine type of guy, but, cold beers in China, follow with foot massage - I'M IN ;D

shanghai-shanghai-shanghai.....I was there 3 months ago, quite a bit of traffic.

I recently got A7R + Zeiss FE 55mm as my travel camera. I do plan to add another lens(wider) to this system. I have stopped bringing my 5D III + L lenses to China last 3-4 trips.

actually i'm more a red wine kind of guy too so make that a few bottles of red
if you are going to the photography shop (xingguang photographics) in shanghai book to stay at the ramada peace hotel
on xietu lu its near the intersection of xietu lu and luban lu and close to heaps of other good stuff and you can walk to the bund which takes and hour or so but its a nice photo walk on the way (the ramada is right accross the road from xingguang anyway if you wanna catch up in shanghai and go take some pics pm me and we can see how our schedules look.

That is the first small camera I would love to have. But, I stopped buying Canon products about a year ago now. IMO, they are forgetting the crop sensor crowd. Been waiting for the 7D II for two years now.
I personally am buying the Pentax K-3 and shelving my Canon gear in two months. They either get something out for us crop sensor fans. Or I will sell my Canon gear.
And I love my Canon lenses, but am tired of waiting.

The 500mm lenses are made to the highest reasonable standards. Lenses can be better, At that level, you would pay 10X the price for 0,1% improvement.

Making lenses like the 500mmL is a work of art. The lenses are made to very exacting standards, but even then, there is variability.

Here are 3 videos showing manufacture of a Canon Supertele lens.

I like to set M mode so that the main dial is aperture and the quick dial is shutter speed (similar to AV mode)

So do I. But I've always shot bracketed shots in Av.

Mostly shot HDRs in Av except if I plan to stitch them to make a pan

Here's a follow-up with an example of why a C-PL can be helpful for a super-telephoto lens. Here's a shot with no polarization (top) and a second shot with about 80% polarization (bottom). Were the light any harsher, the first shot would have had way too much glare on the scales to the point on being unusable, while the second would work fine. These images are unprocessed to show the full difference between the two shots:

Another vote of confidence for CPS Irvine. I've had nothing but great service from them.

Hi Surapon,
I haven't posted in a very long time, but this seems like a nice topic.

Here's a few from my trusty 5D Mk II.

By the way - I find your posts and your attitude in general to by very positive and inspiring. Thanks!

Yes, but what I was more interested in was whether having tight restrictions on the process (tripod mounted, everything still for 20 seconds) was of potential interest to folks. I could see using it in some product, landscape, and architectural work, but it sounds very limiting.

Click to expand...

The first digital still camera software I used was called Snappy Video and was bundled with a capture card that captured analog video frames from a camcorder, and merged them together to produce a still frame. You could get 640 X 480 or 1024 X 768 this way from otherwise very low resolution video. This was about 1995, consumer level digital still cameras came shortly after, and then in a few years, the card was obsolete. There was and still is quite a bit of interest in it, and the price was not out of sight.

I think it used the same basic technique, each frame registered slightly differently due to movement and vibration of the analog video camcorder

http://www.saao.ac.za/~wpk/snappy/

That would be a stretch to be able to spot a new 7D Mark II on your Hi-Def TV but maybe if you are there, standing in the middle of a gaggle of pro photographers you could spot such an elusive camera. I think the arrival of the Sony alpha 6000, Fujifilm X-T1 and Panasonic GH4 have given Canon a serious pause. These are all very capable cameras being offered at a very reasonable price. The sluggish AF that used to be the achilles heal of mirrorless cameras is no longer a handicap. Repackaging the sensor from the 70D into a weather-sealed body and adding a few extra AF points and DIGIC 6 processor just won't cut it any more. Canon really needs a major technology breakthrough to re-establish their dominance in the advanced /serious amateur segment.

Very impressive. It is a way to justify the high price of modern lenses. Tamron 150-600 also seems quite well done. Actually, the litmus test would be to see a full version, but with metal parts replaced with clear acrylic to see the focus settings acting like a real lens.

Enjoy the weekend and your experiences with the 5DIII .

And, at the risk of sounding a little snarky, but how exactly is borrowing a 5DIII "taking the plunge"? ???

Click to expand...

I didn't take this as snarky - no worries. Yea, I probably should have worded that differently. Remember the quote "know thyself"? I do know myself and I've just started the countdown timer. So, in a way it was like "taking the plunge" - just without paying for it yet

regarding the link above

"The Canon EOS 6D may deliver lower resolution images (20mp vs 22mp), however this gives the 6D the benefit of lower noise at higher ISOs. "

NO, it means that Canon has a better way to deal with color noise and banding in 6D .

It is surprising that so many test pages do not understand the difference and think that less resolution has a positive effect on high iso

As an example, the 6D with higher resolution than 1DX has better signal/ noise ratio at 51000iso than the 1dx

Click to expand...

Well 51k look quite good in JPEG, but I'd rather see the RAWs...expsoing to the right yields usable pics at ISO 16k on the 5D3 but I hope it will improve in upcoming bodies and I strongly hope Canon keep their MPs within the 22 MP range...

Besides the general drawbacks of adapting such a non-native lens to a DSLR, you will have to focus it most probably manually (I don't know which Minolta/Canon EF adapters are available). The problem is that the focusing screens in modern DSLRs do not support manual focusing of such superfast lenses with paper thin depth-of-field anymore, says at least Ken Rockwell (read the paragraph just right over the lense's picture in http://www.kenrockwell.com/canon/lenses/50mm-f1.htm). I don't know if he is right, but I can tell from my own practical experience with my Canon EF 85mm/1.2 that I would miss most shots wide open if I couldn't rely on the (great) AF system of my 5D3. Plus, the 5D3's VF indeed does not help me much focusing this lens manually, at least if I shoot moving objects (= people), but maybe I am not skilled enough.

Such vintage Minolta glass is really intriguing, but it may make more sense to adapt such a beast to a mirrorless body that offers manual focus peaking in its EVF, which is not (yet?) available from Canon. Plus, you won't lose focusing at infinity with such a smaller body + adapter.
