Lenses / Re: EF-S 10-18 f/4.5-5.6 IS STM Image Samples
« on: May 31, 2014, 11:33:37 PM »
So, I'd thought I'd stop by my local store to see when these would be coming in...and to my surprise, they already had some! Long story short, I walked out with one. I do not have any experience with the 10-22, although I do have the 11-22 for the EOS M (and the 16-35 2.8 for FF).

First impressions...

- The one thing that jumped out at me immediately is how LIGHT this thing is...definitely easy on the arms - balances well on the SL1, too. Great size for traveling.

- Unlike the 16-35 (and 10-22, I believe), but similar to the 11-22, this is NOT an internal zooming lens...the barrel is slightly extended at 10mm, retracts into the body until about 15mm and then extends again SLIGHTLY until 18mm. It barely extends out, though - probably a centimeter at most.

- This has the "STM" focusing mechanism just like all of Canon's newer entry-level lenses...mainly optimized for video. It is virtually silent in a normal environment (in a super-quiet room, you CAN hear a faint, high-pitched whine as the lens focuses).

- The filter size is 67mm, and the front thread (?) does not rotate when focusing.

- For those that have the M + adapter: there is a noticeable difference in FOV between 11mm and 10mm (this lens can go wider), and this lens is light enough so this could be another UWA option to consider.

So, overall thoughts...


- Light, compact, easy for travel

- Very good center sharpness throughout the range

- IS works well (I was able to get keepers down to 1/4...for those using it with a 70D or larger camera you can likely do better)
- Very affordable at $300, and very high price/performance ratio


- Some edge/corner softness observed, particularly at 10mm

- Purple fringing showed up in a few of my shots (wide end)


So...I think that this is a great lens for the money, although those looking for top UWA performance will want to look elsewhere (and likely will, anyway). Compared to the 11-22, I found the 10-18 to be softer near the corners...but that's more of a testament to how outstanding the 11-22 is, more so than a condemnation of the 10-18. Compared to the 16-35 on FF, the difference between center and corner sharpness seems less drastic on the 10-18. Unfortunately I cannot compare it to the 10-22, so I'll leave that one to someone else...

In the end, I wasn't blown away...then again, I didn't necessarily expect to be. But it is what it is - an entry-level/travel-sized UWA lens, and for $300, I'm not going to complain too much. It is plenty good enough for vacation snapshots and casual shooting. I can be pretty demanding when it comes to IQ, anyway.

EOS Bodies - For Stills / Re: Canon 1D Mark IV or 1Dx?
« on: May 30, 2014, 07:45:38 PM »
General questions I have along the same line of the topic...

How about these two cameras (specifically a 1D IV) vs, say, a 7D? There's nothing like the 7D but on occasion I will find myself shooting at a poorly lit ice show and I find the 7D can really struggle in those conditions. Yet, I don't want to give up the reach it offers over FF (I'm willing to give up SOME quality for greater reach to put more pixels on the subject)...I'm part of that long line queuing up for a 7D II...sold my 60D thinking it would be out last year and since the 70D wasn't available in time, picked up a used 7D. Great drive, much faster but really had a tough time in the dimly-lit arena. I *could* get by with the 7D for this year but I find myself looking for alternatives.


Lenses / Re: buy the 24-70 4 IS... or wait for the 2.8 IS?

I think you could be waiting a while. Better to get what you need now and then whenever it comes out, trade up.

Only reason to wait is if you have no real need for such a lens in the near future.

EOS-M / Re: NEW 10-18 IS STM Test Shots with EOS-M
« on: May 27, 2014, 01:10:40 PM »

I recall Canon once stated about another lens, "has a silver ring for a luxury touch."   ;)


Maybe Canon should make a Blue Ring or double silver ring for their STM lenses. That would be cool.

IMO, STM lenses at the moment are too under-rated. It's my experience on the M that STM performs better than USM, but that could just be the M.

Canon's consumer kit lenses have been crap for the longest time, but I gotta say...I must admit that their newest line of entry-level STM lenses (after spending some time with them) is actually quite good. Are they "L" quality? No. But they are FAR better than the old lenses, and are actually usable now as a lightweight travel/alternative choice when one doesn't wish to risk more expensive equipment.

I've tried out the 55-250 STM and can compare it to my experience with the 70-300L (on a 7D). Sharpness seems similar(!), maybe with the 70-300 having the edge at wide-open telephoto...the biggest difference seems to be in color rendition. The 55-250 images do lack a certain punch (dull) and need more work in post...I also find the STM focus system to be slower than USM, which factors into servo performance, although the STM did just fine for the concerts I shot...wouldn't recommend for professional use or situations where IQ is critical...but it more than holds its own and when you look at price/performance ratio, it's hard to beat. My point is that Canon's newer STMs are CONSIDERABLY better than the junk they're replacing.

I'll be interested in taking a look at this new 10-18. Seems like the biggest issue is getting good corner performance so hopefully it delivers.

... a 100% view of that area. Or a user-assignable button - like on nikon dslrs.

Or some Canon dSLRs.  I have 100% review of the selected/used AF point assigned to the Set button of my 1D X.

Yes. Which other canon eos models carry that feature at the moment?

5DIII can, perhaps some other recent bodies too, not sure.

6D can do it too.

I can only speak from experience...but despite the 7D's advanced focusing system, I find it to be the least accurate/most inconsistent of all the bodies I've used, and this even includes the tiny SL1.

The variability of AF in a single framing can be dramatic from shot to shot. If I take 5 shots in a row, 1 of them will be OOF (sometimes 2, other times none). I've never experienced such variability with any of my other cameras.

However...in terms of speed and responsiveness, there's nothing like it when it comes to shooting action. Even the 5D3 means I have to sacrifice reach...the speed and buffer capacity of the 7D is unmatched in the "crop" department. AF inconsistency and poor high ISO performance are the trade offs.


As for 70D vs. 6D...best to try each of them if you can and put them through their paces.

Lenses / Re: Canon EF 16-35 f/4L IS Sample Images
« on: May 21, 2014, 03:50:00 PM »
Interesting, thanks for the samples.

Just wish it was 2.8, that's all. Maybe that's coming later. The existing 16-35 2.8 I find to be just OK, plagued by super-soft corners even stopped down (seems like this phenomenon is worst at infinity focus). In fact, the quality drop-off from center to edges can be striking sometimes...

But...at least it gets to 2.8 for usability indoors. That's enough for me to keep it for now. Although...admittedly I'd sooner grab the 24-70 for events...

I'll wait for reviews first. The thing is though, already having an M/11-22 on top of the 16-35 2.8 wouldn't make this an attractive option for me. But I am curious to see how it performs. The 11-22 is quite good. If this new lens can match that on an FF sensor, that's a good thing.


Don't see it being an upgrade path for 16-35 2.8 owners though. Now, perhaps a 14-24 might be something to look at.

Well, those 2 lenses are targeted at different markets.

The 24-70 f/4 is targeted at the lower end of the market where IS (shooting at slow shutter speeds or have shaky hands) and wants closeup/short 'macro' operation with fairly good image quality, but not top end.

You may be interested to know that I have a friend and colleague who must be one of the most financially successful photographers in recent times - we're talking $400,000 yachts here, all genuinely from photography - and he now uses a 24-70 f4 IS.

It's inaccurate to say it's not aimed at 'top end'.

I'm tempted to say the 24-70 f2.8 II is aimed as much at very wealthy hobbyists as much as professionals who want the best possible IQ straight off the camera but I don't have any hard evidence for this, so I'd better not  ;)
Or it could be that the 24-70F4 and the 70-200F4 are targeted towards outdoors shooters who have to carry their gear a long way. Realistically, there is no IQ difference between the F4s and the F2.8s,  the trade-off is weight for speed.

Sadly, in my experience that's only the case with the 70-200s (the 4 and 2.8 are both spectacular and you just pay for speed) . However, the 24-70 f/4 just isn't on the same level as the 2.8 version...sorry to say. Other than IS, I find it to be optically inferior (at least the ones I've tried) in almost every aspect (except maybe at 24mm). In particular it is quite underwhelming around 50mm. Maybe that's an optical compromise Canon had to make in order to fit the Macro feature in...otherwise I am sure they could have made it every bit as good as the 2.8, perhaps even better. This is not to say it is a bad lens...but I do think it is overpriced (I expect better at $1.5K price point - if it were $800, it would be an excellent alternative to the 24-105) and other lenses offer much better price/performance ratios.

I haven't had this exact experience, but there have been many times where people pick different shots out of a set than I would have. Or, a shot that I find to be just OK ends up being favorited. Sometimes it's fascinating. We all have different tastes ;)

Lenses / Re: 135L v 85 1.8
« on: May 03, 2014, 02:25:03 AM »
I used to have the 85 1.8, but ended up selling it (among other things) to get the 70-200 2.8. Don't regret it, although I did miss the 85 on a couple of occasions. I got a good deal on a 135 about a year ago as well.

Now I have the 100 f2 (great little lens to couple with the SL1 for "discreetness") and I find it to be a hair better than the 85, specifically in handling purple fringing. The 85 at 1.8 I think is the worst case of PF I've ever seen during my DSLR shooting days. However, both the 85 and 100 can't match the performance of the 135 or the 70-200 (can't expect them to). Softness wide open, PF hold the former 2 back. However, I find that all 4 focus VERY quickly - fast enough for sports use.

EOS-M / Re: EOS M Lens survey - your favorites, and your most wanted?
« on: March 25, 2014, 03:18:03 PM »
I have the M and all 3 of the EF-M lenses.

I find I use the 18-55 most with it (mostly work use), but paired with the 22 the M really becomes an excellent pocket companion to a DSLR setup when I'm shooting for fun - and unlike a P&S, actually provides images with comparable quality. So I'd say the 22 is my favorite.

But often times, 18mm is not wide enough for certain landscape shots...this is where the 11-22 comes in. However, I've yet to use it outside a test session I conducted when I first got the lens. I think that may change, though.

I USED to have a list of lenses I wanted, but now I just use my DSLR...picked up an SL1 on the cheap and at least I can count on those needs being fulfilled by existing EF lenses...if/when Canon decides to finally commit to the EF-M line, we'll see what happens. A macro lens should be next...

Sounds like it's only a minor upgrade anyway. It doesn't even have the 70D's dual pixel technology, so no big loss as far as I'm concerned. I do have the original M.

Lenses / Re: 70-200mm F 2.8 IS 2 VS 70-200mm F4 IS
« on: November 19, 2013, 07:49:49 PM »
I used the 4 for a couple of years and it's a great lens. Loved it.

But - there came a point where I needed that extra stop and it was time to step up. Too many events I was shooting called for a telephoto lens indoors. Struggled with ISO at f4 (on 1.6x)...traded up to the 2.8 and don't regret it one bit. In fact, that is one of my most frequently used lenses especially now with an FF camera. Yes, the extra weight can be burdensome (even somewhat painful at times) but when I look at the pics afterward, I know that it was totally worth it!
