Tamron 100-400 f4.5-6.3 Wouldn't it be nice...

**TwoUptons** · 09-15-2017, 04:12 PM

... in our favorite mount...

It seems like something that would fill a really empty place in the market... A full-frame upgrade over the 3rd party 70-300s without getting into the size or expense of the DFA 150-450.

Any hints that the Canikon exclusivity will be temporary? I noticed it's also not in Sony, so maybe?

One can hope...

Tamron has exactly one lens for E mount. Why would that change? Even partial ownership by Sony can't get them to support the A mount anymore...

What boriscleto said, plus Pentax is in the same boat as Sony, Fuji, Olympus, and Panasonic: Not that many 3rd party options, mainly all-manual options (even fewer AF options)

And the 3rd party options that are available for Pentax are pretty long in the tooth (4+ years old).

Lens mounts are not compatible between brands of cameras, that's something wanted in the ILC industry to make it difficult for customers to swap from one camera brand to another. If you'd have a Tamron lens with the Canon mount, it's like having a Canon lens. That same lens wouldn't work on Nikon, so if Nikon was making a new camera model that Canon don't have, you could ask Canon when they are going to made the same camera as Nikon so that you can use the lens you already have. That is why, it is not good to buy one lens at a time or one camera at a time, when making the choice of camera brand, it is good to consider buying the whole system.

More often than not, reading posts, I have the feeling that people are getting more pleasure out of buying things than taking photos with what they already have.

What always struck me is that 100-400 is the most useless focal length range for a zoom on full frame. It was invented by Canon in order to sell a long lens for crop DSLR (50D etc..) to the amateur without cannibalizing the sales of Canon long primes such as 400f2.8 500 f4, 600 f4. Nikon also had their 80-400 and Pentax copied many years later with sticking a DFA on it. Practically, a light weight 100-400 for landscape is mostly too long and still too heavy, and for action shots on full frame the aperture is too slow, and for wildlife on full frame 400mm is too short. Practically, that kind of 100-400 is for apsc DSLR users on a budget, but it is not the best choice, although a lot of people buy what they are told to buy. The right long zoom to have is DFA70-200 f2.8 for sports and portraiture, and light weight 70-210 f4-5.6 for landscape in addition to 24-105 f4-5.6, and then a 500 f4 (750 f5.6 when used with TC) or 600 f4 (900+ with TC) for wildlife.

Canon 100-400 zooms are very much sold, we see a lot of wildlife photography beginners who just came out of the canon shop, walking in national parks and coming back home with not even half decent bird photo. Typically, the guy buying a 100-400 will walk an scare away animal of which he'll take photos of flying away birds. Eventually, 10% of them will realize they need to get in a hide to get closer and get a decent photo, and once in the hide they'll realize 400mm is too short, then a few percent of them will bite the bullet and get themselves at 500 f4 or 600 f4, and the rest will stay home.

How I wish Pentax would have one like this but maybe, with a little faster aperture. It would be nice if it would also be like the Nikon's focal length 80-400. Probably it would be best if it will be a dedicated APS-C lens. At times I feel 300 is a little short for my needs. I'm not into bird watching but at times it just feels right to shoot at a longer distance.

Yes it would be nice. Incredible even. That lens is right up my alley.

But I don't see it happening. Ricoh want you to buy the pricey (and heavy) 150-450mm lens they produce. Tamron doesn't offer their f/1.8 SP primes or SP 70-300mm and those have been around. So there is nothing to say Tamron will make an about face and offer this 100-400mm lens in K either.

Sadly, if you want these kind of lenses you must go with Canikon.

**TwoUptons** · 09-16-2017, 07:01 AM

Well, I was thinking it would be an outstanding air show lens, where the weather is generally nice but there isn't always a good place for a tripod.

And a good partner for the 28-105 for travel...

I believe you are right in everything you said. We won't see a Tamron in the K-mount and Pentax wants us to buy the 150-450. The 150-450 is a fine lens and that's for sure. However, it's just too heavy to go around. That's why I won't get one.
