Help me with some logic

[Martin Ocando]

I'm quite committed to get the A7R V as soon as possible. Many reasons for it. Tariffs being one of them.

So I can't cover the cost of 2.9K (average on eBay or mpb.com), so I'm willing to sell some of my gear.

My best bargaining chip is the 70-200 f/4 Macro OSS II and the 1.4x TC. I got a quote from mpb.com for $1,320 for the 70-200 and $235 for the TC. Then I can put that plus a G95 and 12-35mm to get the A7R V.

So:

- $1,320 for the 70-200 + 235 for the TC = $1,555
- G95 + 12-35 f/2.8 = $595

Total: $2,150

Cost of A7R V on mpb.com: $3,089 - $2,150 = $939, give or take $1K including tax

Once I get it, I'll sell my A7RIV, already got a quote for around $1,200, and the Tamron 50-400mm I'm eyeing is around $1K, so I'll have an extra $200 of the whole transaction.

My reasoning is that, I'm almost always using the 70-200mm with the TC, and I just got the amazing TTArtisan 75mm f/2 for portraiture, so I'm not using the 70-200 too much anymore, and I have some trips coming that I could really use the extra reach (Planning on Palouse, and maybe Yosemite).

I can consider getting the 2x TC, but that'll make a 400 f/8, while the Tamron is f/6.3. And still can't get the A7R V

Does this makes sense to you? I mean, I paid $1,425 and $415 respectively, so I'll be loosing $755 for the sale, and while it hurts I can't expect to get what I paid.

I'm open to any suggestions.

 

[Impulses]

Makes sense to me, but I'm pretty biased on the matter (the 50-400 is the only tele zoom I carry)... The kit change that is, the hit to the wallet is a very personal matter. I've thought about when to upgrade to a Mk V but haven't taken it very far, and won't rush it because of a mercurial policy or POTUS.

 

[Maoby]

And what are the real reasons for wanting to move from 7R IV to 7R V, I said the real reasons?

 

[The Ryantist]

I sell to MPB often, but there's one catch. The trade-in of your gear is done AFTER tax, so you'll pay sales tax on the full $3000 for your A7RV, not just the $900 difference. Maybe you already included that in your calculations. For this reason I don't like to "trade-in" to MPB. I treat the selling and buying as two separate transactions.

 

[Martin Ocando]

And what are the real reasons for wanting to move from 7R IV to 7R V, I said the real reasons?

Some features are considerable improvements, others good to haves:

• Much better IBIS, crucial for long lenses without tripod
• Improved tracking AF and subject recognition
• Faster SD/CF read/write speed
• Countdown timer on Bulb (this is big for me)
• Lossless RAW
• Big jump on EVF and rear screen quality
• Fully tilting and flipping screen, also big for me
• Considerable better smartphone app (The old one is painfully unstable and unreliable)
• Some say menu is better laid out and easier to follow, that's debatable

And finally: I can still get a good price for my A7R IV, so before it looses more resale value, I prefer to make the jump.

The fact that tariffs might affect the used market is a bit concerning, but not on the top of my priorities.

Agree, I'm following a few offers on eBay and I think I'm going to go with one of them.

Yeah, I think is a calculated risk, and it teaches me not to rush but research further before making decisions. I went to the 70-200 like a hawk having experienced the Canon 70-200 f/4 many years ago, but 200mm wasn't going to be enough, so instead of pilling TCs, I rather go with the 50-400 which makes so much sense.

I'll keep the 20-70 as is the perfect travel lens, the 35mm f/2.8 which is a delight to carry when going extra light, and the new acquisition of the 75mm f/2 which is such a bargain for so much that you receive. So I feel is a pretty solid kit for years to come, and for many of the intended locations I plan to visit soon.

So I can't cover the cost of 2.9K (average on eBay or mpb.com), so I'm willing to sell some of my gear.

My best bargaining chip is the 70-200 f/4 Macro OSS II and the 1.4x TC. I got a quote from mpb.com for $1,320 for the 70-200 and $235 for the TC. Then I can put that plus a G95 and 12-35mm to get the A7R V.

So:

- $1,320 for the 70-200 + 235 for the TC = $1,555

The exchange of Sony 70-200mm GII & 1.4x/2x TCs against the Tamron 50-400mm, for me, personally would be a "no brainer" (especially when using high resolution R cameras). The optical quality of the Tamron lens is at least as good as the Sony GII and with TCs (1.4x or even 2x) performance is poor compared to the Tamron at comparable focal lengths. See e.g. here by yourself:

Loading…

www.the-digital-picture.com

A consideration is whether you really "need" 50-400mm: the Tamron 50-300mm is cheaper and performs similar to the 50-400mm, which gets a bit soft at 400mm (but still much better compared to the Sony + 2xTC). On the other side, the 50-300mm does not accept TCs, so a little soft 400mm may be better than nothing...

I do not think the "macro" mode of the Sony is worth a lot: 0.5x is not really macro and with extension tubes (or diopters in front) you can make also macro with the Tamron lens at any scale...

What concerns exchange of A7R mark IV against mark V, only you yourself can know whether it is worth for you (I use my A7R5 mostly for underwater photography, where AF(&tracking) is essential for macro photography with Sony 90mm macro lens. Only mark V does this job at real satisfaction, but for my surface photos the mark IV would do it pretty as well)...

Or with the 75mm f/2.

It does. There are other improvements I'm looking forward to.

Trust me, I KNOW what you are going through... at least you are doing a parallel move withing the Sony eco system, I came from another brand altogether.

I ended up doing an Excel spreadsheet, and I had a few price columns, high, low, and what I actually got. Coming from another brand, I had to really take that leap of faith once my main body sold, and my favorite lenses, it felt like Cortez burning his ships. Scary but now that it is over with looking back a few years, I am SO GLAD I did it when I did, because my old brand is tanking on resale value now and I would have to have a huge out of pocket to do the same thing today, where as I came pretty close to breaking even.

Now, that statement could be misleading, I broke even because I had accumulated a TON of my old brand stuff, and I targeted a smaller number of essential high-quality pieces coming to E-Mount.

I suggest doing the spreadsheet and tracking as you go... Trade ins are usually not great, if they are giving you a lot, they are probably jacking on the buying side, and usually is more likely visa verse, giving you very little, then giving you a small percentage discount if applying to a new purchase. You could usually do better with individual sales rather than trade-ins. I chose to list my stuff in classifieds on one of the forums and got much better prices from people who were into that brand on those dedicated forums. But... it was a bit of work, stressful, time consuming and a lot of trips to ship stuff and hoping people were ok with the item. Not everyone might be up to the task, but if financially strapped, well, ya do what ya gotta do. FWIW, I got my RV Open Box from B&H and had them add an aftermarket warranty, which still was a lot cheaper than new.

The RV is a great camera, I hope you get some good ideas from this forum and can reach your goal!

How does using 2 separate transactions save on the tax for the a7rv?

You are talking about me, right? LOL

I sold 2 camera bodies, 3 f/2.8 Leica zooms, 4 Leica primes and 3 other zooms to get the A7R IV + 20-70 f/4+ 70-200 f/4 + 1.4TC + 35 f/2.8. I broke even since the Leica gear helped a lot. And surprisingly enough, I though the Lumix GX9 was going to be hard to sell, and it actually sold higher than the other bodies.

I still have a G95 and a 12-35mm f/2.8 that I'm going to use for the RV.

Sadly, I don't have a marketplace that I can trust here in Panama. I have to use mpb.com. I can't even use Ebay as shipping from here is a nightmare. So I have a work trip to LA on the 20th and will bring all the gear and send it to mpb.com.

Besides, I spent $1,855 for the 70-200 + 1.4TX, and I will be selling them for $1,555, so my math was wrong on my original post. Is not a $755 loss, just $300, which is not bad at all.

The RV is a great camera, I hope you get some good ideas from this forum and can reach your goal!

Thanks. Looking forward to it.

The 50-400 can do 1:2 and 1:2.5 thru a good chunk of it's short end too (70 & 100mm respectively IIRC, 1:4 at 400mm), and I still think TDP got a bad sample or had some test issues cause I've never noticed the long end to be particularly soft and other reviews don't reflect that...

For me the versatility is unbeatable, when I don't need to go very long I'm fine with a 75 or 135mm and a little cropping, keeps the bulk down... But when I do wanna go long it's for really really compressed landscapes or wildlife and 300mm is kinda no man's land for that (for my taste), 400mm and 600mm in crop mode is much nicer. Going much longer increases weight and bulk exponentially...

I won't link any reviews or samples cause I think I've already done that in the past when you've alluded to the TDP review.

It doesn't. I meant that I just think of them as 2 separate things. Sell to MPB. Then buy from MPB or anywhere.

 

[Martin Ocando]

I'm in LA, Long Beach specifically, and just sent my 70-200mm f/4 Macro OSS II, 1.4x TC, Lumix G95, Lumix 12-35mm f/2.8 and an old Olympus camera grip to MPB.com. At the end, I decided for the trading option, and the reason is that when I receive a wire from the US to my bank account in Panama, the sender takes a fee, and my bank also charges me another fee. At the end is going to be more than the tax I'll pay if I just trade.

So, if everything goes as planned, my A7R V should arrive in a couple of weeks. I already purchased the 50-300 which should arrive next week. I decided not to buy it locally in LA since online I can use PayPal Pay-in-4, which allows me to finance it interest free in 4 installments every 2 weeks, which is cool.

So I'll have to cover this visit to LA with the 20-70mm only. I think I'll be visiting the Queen Mary tomorrow afternoon or on Thursday, and I'll walk around the Aquarium.

[dcstep]

I don't see in "logic" in selling excellent lenses to buy the next, incremental body upgrade that'll be out of date in six months.

 

[SafariBob]

It makes no sense to me. The difference between the a7rv and the a7riv is fairly limited imo. It really boils down to better ibis, slightly better af in certain circumstances and the 8k - if you use it. Both the ibis and the af improvements are not that relevant in use cases where the r series excels, and the a7riv is already good enough for any situation short of something that requires a stacked sensor.

 

[SafariBob]

And what are the real reasons for wanting to move from 7R IV to 7R V, I said the real reasons?

Some features are considerable improvements, others good to haves:

• Much better IBIS, crucial for long lenses without tripod

the ibis is better, but not to an extent where I think you can get 61mp with long lenses and no tripod.

• Improved tracking AF and subject recognition

yes. This is very use case specific. Most use cases you won’t notice.

• Faster SD/CF read/write speed

agree that would be nice to have, but hardly a reason to upgrade.

• Countdown timer on Bulb (this is big for me)

ok. Cool. But a reason to upgrade?

• Lossless RAW

doesnt the a7riv already have this? In any case, who cares?

• Big jump on EVF and rear screen quality

you’ll get used to whatever and never notice

• Fully tilting and flipping screen, also big for me

Interesting.

• Considerable better smartphone app (The old one is painfully unstable and unreliable)

I agree the old one is crap. Is the new one better? The old one works thigh.

• Some say menu is better laid out and easier to follow, that's debatable

sure. But again, you will get used to whatever.

And finally: I can still get a good price for my A7R IV, so before it looses more resale value, I prefer to make the jump.

you are still topping up with nearly $2k and selling a lot lenses to finance it.



i could maybe understand it if the 8k was a big deal to you, and you shot a lot of environmental portraits at low depth of field where the increased af accuracy might make it worth while for 61mp. Otherwise, I think you would be much happier upgrading to something more modern, like an a1 or a1ii. Just the no blackout feature is more useful than all of the stuff you list above.

The fact that tariffs might affect the used market is a bit concerning, but not on the top of my priorities.

It makes no sense to me. The difference between the a7rv and the a7riv is fairly limited imo. It really boils down to better ibis, slightly better af in certain circumstances and the 8k - if you use it. Both the ibis and the af improvements are not that relevant in use cases where the r series excels, and the a7riv is already good enough for any situation short of something that requires a stacked sensor.

I should get the A7R V by the end of next week, and I have a 14-day return window, so I'll have both the A7R IV and A7R V with me. I might try to get to Yosemite at least for half a day, still a long shot but it might happen. After thoroughly testing and comparing both and if I truly decide is not worth the update, I can return it as I'll be in LA for the next 3 weeks.

makes sense! The difference always appears larger when you use cameras side by side but, to my recollection, the riv is also meaningfully smaller
