Changes to My Photography



Hey!
So, since getting my hands on the Sigma 10-20mm f/3.5 I have noticed a fundamental shift in the way I approach my landscape photography. Take a look at this first shot:
This is one of the first landscape shots I took. The colours are nice, the composition is okay... it’s a nice photo, I like it. 
Now have a look at this shot:
This is one of the shots I’ve taken with my Sigma ultra-wide. Do you see anything different? Yeah! I’m paying a hell of a lot more attention to my foreground. There are a number of reasons for this:
1.      With a lens this wide, if you have nothing in the foreground the image just seems to fall flat. For example:
2.      With a foreground element you can create leading lines that guide the eye into the image. It would be nice if there were really interesting things in frame to lead the eye to, but when I’m out practicing there isn’t always something interesting to put in the frame. This is a good photo for demonstrating my point, though, even if it isn’t the best shot I ever took:
3.      If I don’t pay attention to my foreground, all of my foreground, I wind up with some unexpected and unwelcome foreground elements:

I am really enjoying my new lens and I think I’ve figured out where G.A.S. comes from.  You see, I have always enjoyed my photography; I love getting out there and looking for the shot, finding the composition, trying to do something different so that my images will stand out. I don’t know if I’ve done that yet, probably not, but I still love trying! Then came the Sigma 10-20 and, oh my god! Not only am I still enjoying going out and shooting, but I am excited to go out and try new stuff with this new glass! My photography has been reinvigorated by acquiring this new piece of gear. See my point? Get what I’m talking about?
Yup. A new piece of gear injects new life into your photography. But what do you do at the end of the honeymoon period - when you’re comfortable with the lens, you know what it can do and what you can do with it? It’s still a great piece of kit, and it still expands your photography, but the thrill is gone. You need something else to get you excited again.
Solution?
Get more gear! You begin to fall into a cycle; you need new gear and you need it more and more often. You have G.A.S! But this is where being a limited-income photographer comes in handy.
It took me a long time to get my ultra-wide glass and it took a lot of thinking; a lot of considering my lens needs, my life needs and my budget before I decided I could get the lens. Then, with my limited budget, I really needed to consider which lens I should get. I narrowed then range down to four choices. The table below gives you the lenses, their pros and their cons.
 
Lens
Pros
Cons

Nikkor AF-P 10-20mm f/4.5-5.6G

Low Price - A$539
Vibration Reduction
Native glass
Low price my arse!*
Variable Aperture

Tamron 10-24mm F/3.5-4.5

Vibration Compensation
Comparatively high price - A$799
Variable Aperture

Tokina 11-16mm f/2.8

Fast constant aperture – f/2.8
No stabilisation
Comparatively high price - A$788

Sigma Lens 10-20mm f/3.5

Fast constant aperture – f/3.5
Cheaper than Tamron &Tokina - A$612
No stabilisation
More expensive than the Nikon – No it ain’t!*

I’m not sure if you noticed – did you see the asterisks in the table? How about the red text? You did? Good! I was afraid I was being a bit too subtle. So what’s my problem? Why is the Nikkor getting the “special” treatment?
The Nikkor has Nikon’s new AF-P autofocus system. The new system uses a pulse drive motor to get focus faster and more precisely than the old AF-S system. Which is great... for some. For others, Like we limited-budget shooters, it means that we are slowly going to run out of new lens options. Why?
Because the new AF-P lenses are not compatible with our older bodies (check out Ken Rockwell’s review of the lens in question for a run-down on compatibility). That means that, if you want to get the Nikkor 10-20mm, you have to buy a new body at the same time. Right now, the best price I can find on a refurbished body (I’m reluctant to go second hand because I’ve done that with other things and yikes!) is A$448 for a Nikon D3400. This means, in turn, that to get a fully functional Nikkor 10-20mm AF-P you have to pay more in the region of A$987. And that’s if there is a refurbished body available. Otherwise you are looking at a minimum of A$1054 for the lens and a new D3400. And, from my perspective, I still wouldn’t be able to use the lens with my loaner D7000.
And it’s just going to get worse as more and more lenses get the new AF-P system. I now find myself having to decide whether to save up for more and better glass or for a new body which will take that new glass. Hmm...
Hang on! I’ll just go with Sigma! The lenses are cheaper, the quality is the same and I can use them with my D3200 and D7000. Sorted!
So... Umm... Bye Bye, Nikon!

I hope you enjoyed the read!

Sigma 10-20mm Learning Curve



So! Shooting ultra wide angle with my Sigma 10-20mm f/3.5.If you didn’t catch my post last Monday, I was talking about challenges I was facing when shooting with this ultra wide glass. Take a look at the shot to the left to see what I mean. Somehow I managed to get a shot where, as you can see, only the centre third of the centre third is really sharp. I could not for the life of me figure out why that was when I first looked at the image. I hadn’t done anything different from any other time I’d taken this sort of shot, except use the new lens.
 
But then I thought about it for a bit. In all my good (i.e. not blurred to all hell) shots with the 10-20mm I had put focus either in the middle or far distance. Like in the waterfall shot to the right; the red dot shows where I was focused and you can see how clean the image looks. With the forest picture I had placed focus, once again, on the red dot. In this case, the red dot was only about 300mm away. I started to suspect that focusing on my foreground element was somehow compressing my depth of field. I know - that doesn’t make sense, right? But I was at f/8 for both of these shots and look at the difference. 


Reinforcement for this conclusion came from examination of this shot:
 I shot this on the same day as the forest photo, and I again went for close focus (red dot). Can you see the ugly corners, particularly the top right? It’s the same effect as the first image. Less pronounced, perhaps, but still there.
So, to test my theory, I took my new lens out in the wrong kind of light again to see what sort of results I got if I stuck to longer focussing distances. Here are some examples of what I got:






What do you think? From what you’ve seen above, does my first theory hold water? Does close focus harsh the background? Let me know your thoughts. 
If you have this lens, I’d love to know your experiences, and if you know where I’m going wrong please tell me!
Another short one, gang. I think this might be the norm moving forward, especially with uni going back soon. As always, I hope you enjoyed the read and I hope you’re checking me out at:

What's News 4



No mucking about, let’s just get straight into the news!
Sigma News
Sigma 14-24mm f/2,8
Sigma has announced their new 14-24mm f/2.8 ART lens for Sigma, Nikon and Canon mounts (anyone got a Sigma camera? If you do, or you know someone who does, let me know, I have questions!). Featuring 17 elements in 11 groups, a 9 blade rounded aperture, a max aperture of f/22 and weighing in at 1150 grams (exactly the same as their 12-24mm f/4 ART lens) this promises to bring the heat to Nikon and Canon. Neither the release date nor price for this new ART lens has been released yet, but as soon as I know, you’ll know. Watch out, Nikon and Canon, because if Sigma start doing their ART, Contemporary and Sport lines for Sony FE mount, I think you’re going to see a mass exodus! Just my opinion.
DJI News
DJI have introduced their DJI Knowledge Quiz to the drones in Australia. The 9 question quiz is designed to test a pilot’s knowledge of “simple safety rules”, and each question must be answered correctly before the pilot can fly. There is no indication of how the pilot might be prevented from flying in the press release, so I’ll make contact with DJI and see what they can tell us.
New DJI Mavic Air
Video News

Red Digital Cinema, in conjunction with Foxconn (an iPhone manufacturer) are getting set to make 8k video cameras available to the consumer market. A spokesperson for the project is quoted as saying that these new caeras will be “a third of the current prices and a third of the current size.” This has got to be big news for the budget videographer, but keep in mind that when they say “a third of the current prices”, what they mean is a third of between $29,000 and $80,000. So 'woohoo' on the 8k cameras, but take it with a grain of salt.

I’m keeping it brief this week, but I’ll keep you up to date on DJI’s potential response to my enquiries, and of course on any other quick snippets of news that that I think are share-worthy! And don’t forget next Monday’s post. Or last Monday’s post! Or any of last year’s posts! And don’t forget tell your friends not to forget my posts!
And let me know what you think of this short-form news. Do you like it? Would you like this sort of quick news summary all the time? Tell me your thoughts!

 
Happy Photography, I hope you enjoyed the read!
