A shot from the widest end of the Tamron 18-270mm.
One which shows the largest possible image size at the close focus distance (I was slightly too close with this one, pushing the focus point behind the eye).
Original file from my 365 project.
Manufacturer's Description: "Tamron's SP AF 14mm f2.8 Aspherical (IF) is an ultra wide angle lens that creates a perspective far beyond the conventional ultra wide. With its larger 2.8 aperture, the main subject practically jumps out of the image. By using two Hybrid Aspherical lens elements, this lens delivers high quality images with minimal light fall off at the image corners. To optimize handling, the lens incorporates a push/pull AF/MF Switchover mechanism on the focus ring. * AF/MF change over mechanism for focusing ring Switching between AF and MF is easily accomplished by sliding the focus ring back and forth. Manually focusing is smooth and precise with the wide focusing ring."
Manufacturer's Description: "Tamron's fast fixed telephoto lens delivers a remarkable and exacting performance, as demanded by todays professionals. Two large LD (Low Dispersion) glass elements in the front group provide high contrast and crystal-clear image quality at f2.8. and the floating focusing system improves optical performance especially at close shooting distances. 9 specially shaped aperture blades form a near perfect circle to create excellent background blur for portraits. The true value of this lens is apparent when photographing sports, low-light theatre performances and wildlife. Available in Canon, Nikon and Minolta AF fittings. The lens also features a new AF/MF switchover mechanism* * AF/MF change over mechanism for focusing ring Switching between AF and MF is easily accomplished by sliding the focus ring back and forth. Manually focusing is smooth and precise with the wide focusing ring."
Manufacturer's Description: "A standard zoom lens from a wide 28mm to a medium telephoto range of 80mm. The use of aspherical elements in the front group reduces the number of elements required and the use of strong engineering plastic in the barrel makes the body a light 237g."
Manufacturer's Description: "Tamron's conveniently small and lightweight AF28-105 is the perfect standard zoom providing medium telephoto, ideal for close ups and zooming out to true wideangle for group shots, tight indoor spaces and landscapes. Internal Focusing (IF) once only available on professional lenses, permits easy handling and practical use of filters."
Some examples shot with the Canon EF 100mm f2.8. Lens now being sold as I've switched systems and moved to M4/3 with Olympus. Lens is lovely to use and the 100mm focal length reproduces 1:1 magnification without having to get too close to the subject.
I'm not necessarily proud of my sarcastic quips in this thread, but to be honest when someone comes in with that kind of high-brow and derogatory attitude to members, what on earth did he expect? It wasn't even what he'd initially asserted, it was the way he said it and then attacked when people questioned his statement. We're not fluffy bunnies on this site, and to disparage people's expertise...
I had the siggy 150-500 for a while and was very pleased with its performance. If you go for one, note that it has a tendency to be a bit soft at 500 and using it at 475-480 gives a sharper image. I totally agree, I had one and always shot at 475mm and stopped down to F8 you can get very impressive images. I changed mine for the Canon 400mm F5.6L and the Canon 1.4x to make up for the ...
Only ever got ripped off once on ebay, about ten years ago, bizarrely the seller lived just 4 miles away, she claimed that her garage had been burgled and she'd lost everything just before she posted it. There were dozens of disgruntled buyers and police were involved.. If it's been a while since I last used my account for selling and I want to sell an item ebay will revalidate me, they will...

Thanks, I appreciate your response. Take my critics with a pinch of salt, putting your work at public discussion makes you liable to any sort of critical views. I tried to outline some ways of improving your work, it is really up to you to see them as helpful or not. There are certain standards of this sort of tests though and DxO kindly mentionrd by Chris comes at the top of them. While...
Mike - thanks for that bit of information! I've not used Kenko and didn't even know Tamron made any (I use Canon and Sigma). I based my Kenko info off what others have said and on a photo I saw of one of their line that appeared to have a protruding front element (very shallow, like a coins width in height if I recall right).
I suspect that this issue may be connected to the new focusing system that 70D uses for the live view option. There's probably been some very minor change in the way the AF communicates with the lens that the converter can't cope with hence the lock up. This is a very similar problem to that found with old Sigma lenses and digital EOS bodies, Canon changed a protocol connected with apert...
All AF systems rely on trial and error. That's not true. In PDAF the camera is able to look at an out of focus image and calculate how much it needs to move the lens focus element/s to achieve accurate focus ... Yet PDAF autofocus "hunting" for precise focus is not unheard of. Sure, it happens rather as exception at some extreme conditions, but does happen. Your description of PDAF wo...

I've been shooting Nikon digital cams for years... D300, D700, D90, D600, D7000. The Nikon D810 and D750 are both AMAZING full frame cameras that blow away the competition. Don't take my word for it... read their reviews at http://www.dpreview.com

I had a look at some YouTube videos as well and got my head round it much better. Our physics education at school was somewhat lacking.

Sounds like the brightness of your rear screen is set quite high if the blacks are greyish and it looks overexposed. If you go into the set up options in the menus somewhere there should be an option to adjust the brightness and there you can make it darker.

What i will most like the prime for is corporate portraits as they will all look the same when you do a few. having a zoom means that some people were shot zoomed, others not - processing nightmare. Big learning item. I can think of many instances were you could struggle using that fifty, small training rooms and the like. That 40 is certainly a useful focal length.

Note also that the closer distances increase the effect of body sway, so what you will typically see is not that VR has no use, but that its effect is more muted because the shake the setup is experiencing is that much greater. . This highlights the issue of either being restricted to a tripod, or some freedom when a tripod is not practicable. The effect of increased magnification on camer...
