- This video is all about the image quality. From field of view, to purple fringing, to detail and bokeh. yes there is a difference between these 2 lenses, and with that said, each lens is a trade off of the other. Crazy, I know, but it's true.
If you haven't seen the previous video of the design differences, you'll want to check that out as well.

At 3:24 the older lens is clearly focused on the backboard and knob of the net. The PLM is focused somewhat forward of that. the red ring lens is throwing the background out of focus thus, less contrast. There is a tighter DOF.
Ordered the old version for
Looks like I have another lens to purchase. 😃 Thanks for the comparison! 👍
I couldn't see much sharpness difference between the two lenses in this comparison. I think you were seeing micro differences in the focus accuracy, i.e. when you were referring to the fine hairs on the basketball rope, sometimes they were sharper on the old lens and sometimes on the PLM. Look at 9:22 on the video, it is much sharper on the left (old lens), this is because the area you're looking at is in sharp focus on the old lens and just out of focus on the PLM. The earlier comparisons were the other way around. I agree with your observations on the fringing. However, all in all I'm not seeing a better image on the PLM in this test.
They were pretty dead even even on that shot. The PLM picks very fine details better than the red ring 55-300. Coupled with the fringing and CA, the PLM is a better lens. At least from my experiences.
Red ring wins, better bokeh,sharpness and zoom.
The depth of field at 300mm is not that large. Some changes might be attributed to that. On the 150-450 lens the depth of field is exceedingly small at 450mm. I no longer go to the maximum telephoto immediately and try to use a shorter focal length.
thanks man. Can't wait to get my PLM.
It's an eye opening lens regarding IQ and Autofocus. It checks every box!
Nice comparison! Thanks!!
You're welcome, and thanks for watching 🙂
I'm surprised how sharp the PLM lens is considering it has 2 more elements than the non PLM one. Pentax must have upped their game with the coatings not to have any CA.
It's a shockingly good lens for the price. Every once in a while Pentax absolutely nails one right out of the park 🙂
Excellent to see the comparison, up to now I have been mainly re-using my FF lenses and using my KS2 as a second body. This makes buying more dedicated APS-C lenses compelling and when the new camera is released, a necessity, (and the prices are so much lower!). It is a shame that Ricoh do not seem to release lenses for review, (even if it was just a limited number of dedicated reviewers such as yourself), and that you are limited to reviewing what you buy. It seems such a cheap way to get lense quality showcased, you get more site hits, they get more lense sales, win win. They have Ambassadors showcasing image quality and what can be achieved with Pentax gear, right? Why not Ambassadors showcasing the gear itself? I don't see any of that. Marketing is a funny thing, I haven't seen a TV ad for ANY camera outside a smartphone for... years I would say, the budget seems to have gone, yet Ricoh are the only ones who get flack for lack of marketing, (although for Ricoh it is particularly bad I would say), none of the others or the industry in general get the same criticism ☹. One deficiency in myself videos such as this highlight is that I have never tried the focus tuning options on my camera for a particular lense, could be a good topic for a video? How effective would you say it is and how often should it be done, is it a once off exercise? How likely is it that a particular lense is out and you need to tune for that lense as opposed one universal adjustment for the camera to be aligned across all lenses?
I seem to vaguely one pentax ambassador but he seems to not upload as frequently to TH-cam.
The only one I see here and there on twitter and Instagram is Kerrick James.
That's a good idea. Ambassadors of different genres. The ones they have now showing what's achievable and other Ambassadors showcasing the products themselves. That makes sense! In a matter of speaking, every other camera brand is marketed, at least online. Landing pages of camera store websites, social media influencers, even the manufactures websites. I've even heard radio ads for Canon's annual "Best in Glass" sales event. But have yet to see Pentax represented in any of those forms.
As for the AF fine adjustment, I did do a video about it. I generally do one lens instead of the global option. Reason being, I haven't come across multiple lenses that all required the same adjustment, so doing it globally may correct a couple of lenses but then it would throw all the others off. I only check the adjustment if I'm struggling to nail focus. I have had a couple of cases where I've had to reset the adjustment back to zero for a couple of lenses. It's as though an element slightly moved or something from where it was before. Most of my lenses don't need any adjustments though.
Could the field of view differences be dictating the depth of the hood? Do they design the hood by formula or experiment? The histograms were too small to tell for sure but there appeared to be some slight differences. Of course there is possible differences between examples of the same model. This was a well worthwhile and excellent presentation. I am looking forward to the 35 v 50.
Very good points. Maybe the PLM hood needed to be wider for the field of view. But then it makes one wonder, why a different field of view on a lens with the same focal range? Hmmm
@@KobieMC maybe someone saw a positive small tweek in design, are the various glass components identical, design change based on PLM motor versus screw-drive? I would pose the question on Pentax forums but there would 100 responses covering 300 answers most of which would be well beyond my technical knowledge and ability. (almost everything is)
The lenses are 100% completely different except for the HD coating.
@@KobieMC So do you think the difference in field of view is outside normal variation? Are there industry accepted tolerances? Maybe a comparison to another brand in the same focal range? Maybe we should just have a drink and contemplate the sunset?
True enough... Like why is the sky blue if space is black and no mirror to reflect the oceans. Hmmmm. I am going to check against a Sigma 170-500 APO at 300 mm and see how that matches up. As well, my DA L 50-200 WR at 200 mm to see if the 55-300's match up at 200 mm as well. Now I'm curious as to what's going on. Maybe a rounding tolerance? Like the 5.0 Mustangs that were actually 4.9 Litres.

The WR lens looks like my Tamron lens with a softer picture than the PLM I would not upgrade to the WR lens the PLM is in a different league much sharper lens. I don't use 35mm lenses even though I have them I use 28mm lenses more.
I've coined the PLM as being the D FA 150-450's little brother. Sharp and fast silent focusing.
Wouldn't it make more sense to just keep the iso at 100 for all the tests?
Valid question...
In a completely controlled environment, yes. But by using a fixed ISO when the lighting changes doesn't work. You'd easily end up with one image being exposed completely differently than the other image. Even without changing the lens. It just takes one cloud to change it all.
@@KobieMC but you could leave it on Av and let the shutter speed change?
@@gordonblues843 I could have done that, but for the sake of consistency regarding aperture and shutter speed and my preference of locking those 2 settings when doing a comparison, I chose TaV instead of having shutter speeds varying between both lenses and each shot.
kobie, have you tried the plm lens with your k30?
Yes, but only because I have the K-50 firmware on it so the PLM does work.
@@KobieMC i also convert my k-30 to k-50 firmware too. do you having continious focusing too?
If you mean during video, no. Only the K-70 can do that because it uses a different focusing system.
@@KobieMC no, just during photographing. i don't show video!!😄😄
Continuous focus works fine 👍🏽
I here LOL
