Tamron f2.8 90mm Macro Or 50-135 DA* with Marumi DHG 200 macro filter

Nice shot, especially (for me) when cropped by about 20%. As you know light is king (and lack of wind) so keen to see what you get in more favourable weather. I did take mine out at the weekend, but weather spoiled the show - being in the UK you need to be damn patient to do macros work without additional lighting !

Hope you are happy with your purchase, unless you're under studio conditions there are going to be dozens or hundreds of duff shots to every acceptable one, and my experience is that this is exactly the same when using a low to medium cost dedicated macro lens.

Please do, very keen to see them - I have to admit I've not done too much macro work since posting this ... so another reason not to keep a dedicated macro lens. Maybe your shots will give me a push to get out with it again !

18-135 mm pentax lens

If you have a family or other reason to have such a wide focal range, for occasions when changing lenses will miss the shot, then this lens rocks for the price. For me it was a no brainer kit lens, then I got a 50-135 da* plus a wide prime with the intent to sell the 18-135 ... guess what, its still in my bag, the 50-135 is superb, but with a young family there are occasions where I need more flex.

But bear in mind the quality of the body, the 18-135 is probably as low as you'd want to go for this body - selling it with the DA L 18-55 and DA 18-55 WR is just a bad joke imho.

Great images, really feeding my LBA ... although I love my da* 50-135, whenever there is subject movement there seems to be a lot of
frantic button pressing whilst the camera says "no, dont think so", fast focus its not.

Nope - had been off charge for >8 hrs when it occurred so certainly was not hot at the time or in heavy use at the point it occurred. I just mention as I normally run batteries to flat and just swap a spare then, I don't generally top up battery charge.

I didn't see any other reports and thought important enough to start a new thread. Sorry folks 1.10 is not a fix for the mirror flap lockup, not completely anyhow, it happened to me today for the first time, and I already upgraded from 1.03 to 1.10, just double checked my firmware.

Mode : P
Battery: Pentax original fully charged, no battery grip
SD cards : Pentax Flu and Integral Ultima Pro 64GB Class 10

Note : battery had been probably 2/3 and I had topped it up to full last night knowing I was doing some shooting today.

Unless you have a Pentax auto-focus adaptor, in which case the manuals will autofocus (well strictly the adaptor focusses it).

Tamron f2.8 90mm Macro Or 50-135 DA* with Marumi DHG 200 macro filter

I've been using the Marumi DHG 200. If you go down this route please do post your experience, there does seem to be CA under certain circumstances, but by and large it makes the fantastic DA* 50-135 into an excellent macro lens so long as you stay at or above a "reported" f/6.3 AT ALL TIMES (actual f-number would be around f/3.5), below this I only got garbage.

Using with a step up sounds like it should be fine, quick google for "using step up with close up lens" agrees, but maybe someone here has real experience.

Just looked back at my Iceland shots, unfortunately I had a woeful camera at the time in 2008, so very envious ... actually brought a tear to my eye thinking how good I could do now with better kit ! For me it was the most magical of holidays, with the geysers, hot tubs/springs, volcanoes, black beaches, coloured houses, whales, ice filled lagoon and Oooh the waterfalls, every few minutes it seemed we would stumble on one and you can normally walk right up and into it, and be the only soul for miles. Depending on preference you may want to pack a few ND filters for the falls ... you certainly will not need them to eliminate the people ! We drove across the south to Hofn.

If only I'd had my K3 and lenses when I came across these scenes....

Handheld, not perfect composition but this Marumi really delivers. Camera reporting f/16, so taking account of +5 close up lens thats about f/9.5

I've had a couple with CA but Pentax utility has been able to fix. This one is just saved to jpg with no adjustment at all.

A GREAT shot !

Blimey- we just don't get bugs like that here, and you have the sun over there too, sounds like macro paradise.

Glad your early impressions are good - the DA* 50-135 is such a capable base lens. Keep posting if you get shots like this.

I see you shot at f8 - remember that the effective value* would then be around 4.8 and is very wide, to get decent depth of field I would suggest not going this low, but hey you have a great shot !

* As aperture is focal length divided by diameter of "pupil", adding the Marumi changes the focal length and changes the effective aperture by one and a half whole stops (I think...).

I've been doing some experiments along similar lines, I will do a thread for it but trying the 50-135 at 135 with the old 1.7 AFA, the quality captured with the 1.7 AFA far exceeds the cropped image quality in the early test.

I would be interested if the OP could try these combinations suggested above, based on my experiments my money is going on option #2, and you get AF too.



By the way, the AF I got on the 50-135+1.7AFA was really easy to work with, setting the lens to the rough length is pretty damn easy then let the AFA do its thing. Very glad personally I got the AFA, its what I'm planning to use at kids football etc, to give me some extra reach without big investment.

Depends on priority - personally I'd keep the lens you have for general landscape (unless thats a big thing for you). Push the budget slightlly and go for a DA* 50-135, I just got a second hand one its Amazing, although not the quickest to focus for sports, I see they are selling on ebay around $700 mark plus or minus.

Tamron f2.8 90mm Macro Or 50-135 DA* with Marumi DHG 200 macro filter
Posted By SteveUK
Replies: 10

First a note on exactly how I came to do this stange test, I've invested in some equipment upgrades, a K3 and a Pentax DA* 50-135 chiefly, a DA21mm Limited to complement it. This kit solves well for my prime directive - capture the family, but I once had a nice macro lens and enjoyed it, so I was willing to spend a reasonable amount on a 1:1 macro too for those odd occasions in the garden, not a serious macro enthusiast then, a potterer.

I picked up a mint Tamron 90mm f2.8 lens, it arrives on a sunny English late afternoon, so I'm straight out in the flowerbed, and well its just not delivering, but there is some breeze so maybe its this. On a whim I try putting a Raynox 150 (+4.8) adaptor on my 50-135, results actually look much better, the shutter speeds are way way higher, despite it being a 49mm adapter on a 67mm lens (so visible vignetting) it feels like this is capturing significantly more light. This makes me wonder ... maybe with a more suitable adapter lens that fantastic 50-135 could challenge a real macros lens ... googling finds many +2 +4 +10 filters and a +5 achromatic one from Marumi, the DHG 200, which is a little more expensive at around 100 USD but hey I'm sticking this on the front of a pretty mean camera and a pretty mean lens, and thats a snip compared to the Tamron macro lens.

An online calculator I found suggested that effective f number of the DA* lens with a +5 macro lens would be (reported value) * 80.6/135, so when camera says lens is at f11 the real aperture is around 6.5, and that the magnification would be around 0.96, pretty much 1:1.

So without further nattering I start off with some shots of graph paper indoors using a tripod, flash and remote shutter release, mainly to check depth of field, I'm also adjusting AF, but this is not an AF test.

The graph paper shots (see below crops) told me a couple of things :
1. The online calculator was about right f6.3 on the Tamron is showing a similar depth of field to f11 on the DA*, so the DA* is going to need to be stopped down quite a bit to get reasonable depth of field.
2. Comparing the exposure graph, the DA* is actually delivering a stop or two MORE light than the Tamron.
3. Pixel peeping the Tamron wins, just, a little more fringing showing on the DA*, might be better if DA* had not been over exposed.
4. Working distance of the DA* is now great, just a little longer than the Tamron (normally the closest focus distance of the DA* is 100cm !)
(5. DA* is slightly back focussed and Tamron slightly front focussed before adjustment.)

Crop of DA* at f11


Crop of Tamron at f6.3


Secondly lets move on to something real, an orchid, also indoors and using tripod, flash and remote release. On the face of it both lenses are providing a good sharp pleasing image, slightly nicer colouring in the DA* shot, cropping heavily the DA* shows a little sharper.

Crop of DA* at f13


Crop of Tamron at f6.3


Bottom line for me then - 50-135 DA* with the Marumi DHG 200 keeps up with the Tamron 90mm f2.8 and seems do deliver more light, probably explaining my day 1 flower bed experience where the Tamron simply didn't have a high enough shutter speed to compensate for the image movement. So I've sold the Tamron, good lens, but surplus to requirements as I (obviously) need the DA* for other duties.

Just one persons experience at the end of the day, if I were a hard-core macro enthusiast I would probably keep the Tamron too - still food for thought for those who have invested in a great lens like the 50-135 DA*.

K-3 Mirror Flop Fix From Ricoh

To me, a firmware fix applied on fail only, normally means one of two things :
1. They want to check how it works "in the wild" with users experiencing the issue, before including in normal release.
2. The fix has some negative consequence, e.g. limited battery life.

Suggest one of you guys affected double checks before getting the fix.

Agree, and even further, in Europe I believe the position outlined above by Pentax would not be legal, items such as this are covered against design flaws for up to 6 years. Our redress under this law would be against the seller though (not Pentax directly) ... so a good reason to buy from a reliable supplier !

In reality many major manufacturers (hopefully Pentax) will seek to absolve selliers of this obligation by covering the matter themselves (otherwise they are likely to get destocked by sellers).

Nope - a printed bill from Royal Mail stating the charges that have been levied, a note below stating that they are sorry they cannot enter into ANY conversation on the charges and some (helpful) references to UK tax website for (retrospective) challenges.

I just had emailed courier documents from Japan stating clearly the correct value declared by the sender (in Yen).

Will update on how this goes, I expect resolution will be months - its the tax department after all, they aren't known to be quick at anything.

I bought a DA 21mm f3.2 from ebay for 225, its in Japan, I'm in the UK. A duty & tax bill for 247 arrived on Friday (55 duty, 178 VAT, 13 fees) - did I miss something or did they mess up big-style ? The duty checking site I used said it should be 67 ...

I had to pay the duty to release the lens from customs, apparently I need to fill in a form AFTER I have the package.

What's worse - MY WIFE OPENED THE DUTY LETTER !

For catching the kids, being kids, the DA* 50-135 is my pick. I just got it to replace the DA 18-135 (which too is good). I think I never really understood what people meant about it being about the lens more than the camera until I got the 50-135.

I just got a 1.7X AF adapter to keep in my pocket and make it that bit longer, will post some samples, first sample was equally awesome.
