Review: Canon EF-S 10-18mm f/4.5-5.6 IS STM

5 Jun

This is a quick review of the new Canon EF-S 10-18mm f/4.5-5.6 IS STM with some “random” test footage I shot on my way to a client-meeting. Overall a pretty impressive Lens (especially for the Money) on a APS-C sensor like the CANON EOS 70D but also the Canon C100 since the Autofocus really work quite nice and super silent as well. It seem Canon had video shooting in mind by crating that lens.

Its sharp and has a nice overall look, there are no noticeable real nasty unsharp edges or corners like the Canon 10-22mm or the Tamron 10-24mm. The non-constant aperture is not really a big issue it seems, the iris works kinda smoothly. The lens just is not made for low light … thats all 😉 Zoom-range is OK, I liked the Tamron 10-24mm for the 24mm but its nothing that i really miss on a super wider angle lens.

– makes optically nice & sharp pictures
– great wide-angle look
– great & silent Auto-focus works smooth in Video-mode
– good Images stabilizer (IS)
– good close focus range … almost macro feel to it
– works good for taking stills
– good price (around 270 EUR in Germany and $299 in the US)

– manual focus ring is small and has no hard stops or markings on it so its a bit hard to manually focus
– non-constant aperture
– built quality is not the best / its not exactly weather sealed
– does not come with a Lens Hood

But thats it … it might not work as good on non auto focus cams and is not as super cinematic as a wide open Tokina 11-16mm f2.8 but then again the Canon EF-S 10-18mm is a pretty nice lens for the money after all.

It also is pretty great for taking stills:

Review: Studio Speakers – Samson Resolv A6 vs. M-Audio BX5

20 May


I’ve used quite a few Speakers in the last 12 years (or so) I’ve been working on Audiostuff. I started with some passive Tannoy’s (not so much a fan of those) but over the years i also used:

Yamaha MSP 7 (great speakers) – around 1000 EUR for a pair

EMES Black TV HR Active (unique / rare / kinda good but you really have to get used to them / technically a good concept tho’) around 1400 EUR for a pair

Genelec 1032a (they are good / really analytic – don’t like the overall sound tho’)  around 1800-2000 EUR for a pair

ME-Geithain RL 904 (unique german brand but quite common / really analytic / don’t like the overall sound tho’ you really have to get used to them) around 2500-3000 EUR for a pair

Dynaudio BM6A (really loved them , great speakers) around 1300 EUR for a pair

Fostex pm 0.5 (meh … not so good but better than any common, random plastic PC speaker) around 150-180 EUR for a pair

KRK RP6 RoKit G2 (one of best speaker I’ve used esp. in that price range … great over all sound / powerful, quite balanced, good low-end, analytic but not too much, you actually can kinda enjoy listing to stuff) around 400 EUR for a pair

and i also used some KRK RP5 RoKit G2 on smaller workstations and as Surround speakers – around 290 EUR for a pair

So i really loved the last setup i had: a KRK 5.1 setup with 3x RP6 ‘s and 2x RP5’s. I used that the longest time and really got familiar with it … enjoyed using it.

But then I changed my Job, I did go freelance (as you might know I work for all kinds of projects and people now – like for ScruffyTV (a lot of Podcast work there in addition to other stuff) and even more so on more audio based / orientated stuff) So anyway, I kinda had to leave my beloved KRK setup at my old workplace.

Anyway … now i thought, well lets see how good the cheaper stuff really is – since i got asked a lot what cheap Studio-Speakers people should get, people who just get started. I did quite some research and it seemed that most small and “cheap” speakers (like most 5″ speakers) are not so good for accurate and have not so good sound reproduction for any sound stuff, esp. if you have a pro’ish approach to / for your work. At the end of the day I was kinda left with really only two “low-priced” options:

The quite common M-Audio BX5 and the Samson Resolv A6 both of which got good some notes (so to say) for the low price they go for.

So i got both for a test-run


First of the Samson Resolv A6. The price in Germany is around 175 EUR for a pair, which is actually quite cheap for a pair of 2-way 6.5″ speakers. And for that, they are actually surprisingly good. Keep in mind of a pair of KRK RP6 (same size, almost same spec’s) you pay around 400 EUR (and even that is considered a lower priced speaker). Now they have a lil bit of a lower end issue in terms of not quite power full and precise in that range (so really not like the KRK’s) But if you have a not so good room that actually can be good (if u have a good listing spot and get used to it)

also they are missing a bit in the higher mid range and maybe a little bit of too much emphasized in the 150-300 Hz area but that really shows only in a few tracks (and if u don’t have a perfect placement of the speakers). Over all they are quite good sounding. They have an open sound. For the price range analytic enough to get pro work done. The Stereo-filed is ok, actually good for a Studio-speaker in that price range. I actually was surprised how much really i can hear single instruments in some tracks / mixes.

They have a lil issue with some white noise in “Standby” but that actually should be not a big issue for mixing at all. You only will notice that when you have nothing playing. And if you want to dial in stuff like “noise reduction” on some audio recordings you always could use headphones to make sure its it ok, but really it’s not that bad at all – really just a little bit white noise.

Now, these speakers are quite big and kinda heavy, so for smaller rooms and for people “on the road” a bit too much maybe.

So for a common Edit-Suite setup it might e bit tricky to get a good placement. They are not as uncomplicated to place to get a good sound out of them. I always had the feeling the placement of the KRK’s was less “complicated”. It kinda was like the KRK’s sounded good everywhere. Anyways, sometimes its better to get smaller speakers (like the KRK RP5 RoKit’s – in that size really nothing comes close in the price range). But I did read that the smaller Samson Resolv A5 are not as good as the these bigger Resolv A6. So that is not really an option.

So, over all quite good speakers for the money. Are they as good as KRK RP6 RoKit’s? …not really. But the Resolv A6 are really usable esp. if you just get stared and have to keep your start-investment costs low. If you get experience with them, get to know them – so to say – you really can get work done!

Technical specs are good: a 2-way 6.5″ woven carbon fibre woofer with 75W, 1″ silk dome tweeter with 25W, (so overall 100W) frequency response is in the 40Hz-30kHz, there are XLR and 1/4″ balanced inputs and unbalanced RCA inputs its AV / magnetically  shielded and solid MDF case construction. There is a High Frequency adjustment knob that can be helpful if needed and actually is rare in that price range of speakers. The volume knob is a bit tricky to adjust in lower volume levels so it might take a lil while to get both speakers set to the same level but in the end it works. Oh BTW the low frequency port is on the front … what in my experience is better esp. if you don’t have “perfect” placement of the speakers. (too close to a wall / in a corner)


The other candidates are the M-Audio BX5 – 177 EUR for a pair – (i got the older version so the newer BX5a might be a bit better but overall these are the same). The BX5’s are well made and actually have a good size for smaller rooms and the usual editing suite setup.

In terms of Sound, I’m not so sure. Even though they are quite powerful for the size and have a good strong low-end for the size, they really have a noticeable lag in the mid-range, so they really don’t sound open at all. if you have an orchestral track (movie score) for example there really is all the “wood” and open sound missing… you really have a hard time getting the room and clearness of a mix.

The high range is actually good, maybe a bit too “fine” but quite analytic with a somehow odd “rolloff” tho’. It sounds too sharp in a way.

So in the end I have to say they are not as good as the Samson Resolv 6A. One good thing is tho’ that these speakers are quite common in home studios and even edit suits so people are used to them and it might be possible that you “have to” / might use them at some point.

Technical specs are ok: it’s a overall 70W speaker with a 5″ woofer and 1″ tweeter, magnetically shielded, balanced XLR and balanced/unbalanced TRS inputs, volume control (that actually works good and smooth). The low frequency port is on the back of the speaker  … what in my experience is tricky / not so ideal esp. if you don’t have “perfect” placement of the speakers. (too close to a wall / in a corner) so i kinda noticed a bit of a low end “overload” for some tracks i played … not too bad just something you might keep in mind.

In conclusion: If you don’t have the funds, have to save some money you really could get away with the Samson Resolv A6. They really sound good/ok for the money. If you have the funds go with the KRK RP6 RoKit G2 tho’.

I really would not recommend the M-Audio BX5(a) even though they are common (oddly ;-))  and small they really just sound not right / not good enough to compete with the SAMSON’s or even more so with the KRK’s at all.

At the end of the day – if you really want to deliver a good mix – you really should check speakers for yourself – listen to your reference tracks on them.

As for all speakers  – even the expensive ones – you have to get to know them, you have to get experienced with them (so to say). But don’t get any random audio speaker that doesn’t sound “right” for you.
