Preference On Lens Brand

I was wondering, do you lads have any preference on specific brands for your lenses?

I notice the products list on the right mentioned lenses and there are a few brands mentioned there. Saw it was missing Kowa which I occasionally see passing by.

I usually get annoyed with those brands who advertise with Megapixel lenses, yet fail to state how many pixel it actually supports!

If you go by the revealed preference of the biggest camera manufacturers, Fuji looks to be the most common choice.

We did a lens test with 720p cameras. Fujinon and Tamron overall did the best. I think it's time to do a new test with 1080p cameras and whatever new lenses are available.

Beyond that, the easiest to use varifocal lens I have ever tried is the Pentax Plus (see our test). I do not know if it is that their marketing or sales structure is weak but, despite the technical advances in focusing, rarely do I see people use it.

Good topic!

I regularly test among Fujinon, Tamron, Theia, Pentax, and Computar. Overall, Fujinon has been the best overall for producing image quality in 1-3MP cameras in well lit and low light scenes. Their non Day/Night lenses still perform very well in low light and there is minimal focal shift when using a day/night camera.

Tamron lenses always test ok, but like Computar, I see more trouble with depth of field in these lenses to keep an entire scene in focus. Image quality is good out of these two brands, but Fujinon lenses are competitive on price and have given me better results.

Theia lenses have been the best overall from my testing but they have a gap in their offering with a 1.8-3mm option but then jump to 9-40mm. But they are rated for up to 5MP resolution so you have a lot of flexibility in cameras to use them with and they do offer the ultra wide options without lens distortion. Depth of field is also very good with Theia. If we could get customers to pay the price every time, we would probably use Theia in every project if the mm range works.

As John pointed out, the Pentax lens is the easiest lens to deploy because of the unique focus mechanism. It's just limited to 1.3MP resolution and from my testing still has some trouble using cameras with auto backfocus. They have a similar focus option in a 8-40mm that is rated up to 3MP but it is a massive lens and has a constant f-stop so you will get some depth of field issues.

Kowa still produces great lenses, but their MP lenses are 2-3x in price from everyone else which may be why you don't hear about a lot of people using them.

I hope that helps.

Thumbs up, Keith. Thanks.

Very informative and helpful, thank you!
